Typical properties for CHO-SEAL 1310 and 1273 materi-al are shown on pages 33 and 32respectively.High Shielding PerformanceCHO-SEAL 1310 material provides more than 80 dB of shielding effectiv-ness from 100 MHz to 10 GHz, while CHO-SEAL 1273 material provides more than 100 dB.Low Volume ResistivityBoth materials have exceptionally low volume resistivity, which makes them well suited for grounding appli-cations in which a flexible electrical contact is needed.Low Compression GasketSpacer gaskets are typicallydesigned to function under low deflec-tion forces. Chomerics uses design tools such as Finite Element Analysis (FEA) to accurately predict compres-sion-deflection behavior of various cross section options. Refer to page16.LCP Plastic SpacerLiquid crystal polymer (LCP)spacers, including those made with Vectra A130 material, provide aCHO-SEAL ®1310 or 1273Conductive ElastomersWith EMI spacer gaskets, shielding and grounding are provided by Chomerics’CHO-SEAL 1310 and 1273 conductive elastomers, specifi-cally formulated for custom shape molded parts. They provide excellent shielding and isolation against electro-magnetic interference (EMI), or act as a low impedance ground path between PCB traces and shielding media. Physically tough, these elas-tomers minimize the risk of gasket damage, in contrast to thin-walled extrusions or unsupported molded gaskets.Silicone-based CHO-SEAL 1310and 1273 materials offer excellent resistance to compression set over a wide temperature range, resulting in years of continuous service. CHO-SEAL 1310 material is filled with silver-plated-glass particles, while 1273 utilizes silver-plated-copper filler to provide higher levels of EMI shielding effectiveness.EMI Spacer GasketsThe unique design of Chomerics’EMI spacer gaskets features a thin plastic retainer frame onto which a conductive elastomer is molded. The elastomer can be located inside or outside the retainer frame, as well as on its top and bottom surface. EMI spacer gaskets provide a newapproach to designing EMI gaskets into handheld electronics such as dig-ital cellular phones. Board-to-board spacing is custom designed to fit broad application needs. Customized cross sections and spacer shapes allow for very low closure forcerequirements and a perfect fit in any design or device.Robotic InstallationSpacer gaskets can be installed quickly by robotic application. Integral locater pins in the plastic spacer help ensure accuratepositioning in both manual and pick-and-place assembly. Benefits include faster assembly and lower labor costs.The integrated conductive elastomer/plastic spacer gasket is a low cost,easily installed system for providing EMI shielding and grounding in small electronic enclosures.Figure 1Single Piece EMI Gasket/Locator PinsCHO-SEAL 1310 or 1273 Conductive Elastomer (Inside)Plastic Spacer Around Outsideor InsideApplications for EMI Spacer GasketsThe spacer gasket concept is especially suited to digital and dual board telephone handsets or other handheld electronic devices. It provides a low impedance path between peripheral ground traces on printed circuit boards and components such as:•the conductive coating on a plastic housing•another printed circuit board •the keypad assemblyTypical applications for EMI spacer gaskets include:•Digital cellular, handyphone and personal communications services (PCS) handsets •PCMCIA cards•Global Positioning Systems (GPS)•Radio receivers•Other handheld electronics, e.g.,personal digital assistants (PDAs)•Replacements for metal EMI shield-ing “fences” on printedcircuit boards in wireless tele-communications devicesstable platform for direct, highprecision molding of conductive elas-tomers. The Vectra A130 material described in Table 1 has excellent heat deflection temperature character-istics (489°F, 254°C). For weight con-siderations, the LCP has aspecific gravity of only 1.61. This plas-tic is also 100% recyclable.Typical EMI Spacer Gasket Design ParametersThe EMI spacer gasket concept can be considered using the design parameters shown in Table 2.

This unit specializes in elastomer finite element analysis (FEA) using MARC K6 series software as a foundation for FEA capability.Benefits of FEA include:•Quickly optimizing elastomer gasket designs•Allowing accurate predictions of alternate elastomer design concepts •Eliminating extensive trial and error prototype evaluationTypical use of FEA in EMI spacer gasket designs is to evaluate the force vs. deflection requirements of alternate designs.For example, onespacer design features a continuous bead of con-ductive elastomer molded onto a plastic spacer. An alternative designemploys an “interrupted bead,” where the interrup-tions (gaps left on the plastic frame) are sized to maintain the requiredlevel of EMI shielding. Figure 4illustrates these alternative designs.Gasket DeflectionFigure 5 compares the effect of continuous and interrupted elastomer gasket designs in terms of the force required to deflect the conductive elastomer. This actual cellular handset application required a spacer gasket with interrupted bead to meet desired deflection forces.Chomerics Designand Application ServicesChomerics will custom design a spacer for your application.

It can also time the width of a single pulse.Highest resolution is 0.2 µs, since timing is achieved by counting5.5 MHz clock pulses. For long intervals, the display is updatedcontinuously during timing. Laureate™ stopwatch timers use theFR dual-channel signal conditioner and Standard counter mainboard.• A-A Stopwatch Mode. Time can be measured between astart pulse and a stop pulse, both on Channel A, from eitherthe positive or negative edges.•A-B Stopwatch Mode. Time can also be measured betweena start pulse on Channel A (positive or negative edge) and astop pulse on Channel B (positive or negative edge). Thismode allows inputs from different sources. In addition, the Aand B inputs can be tied together to start the stopwatch withone polarity and stop it with the other polarity.•Rate Based on 1/Time Mode. Highly accurate rate can bedisplayed by taking the inverse of time. Extensive arithmeticcapabilities allow display in engineering units, such asmeter/sec. This mode requires use of an Extended counter.Display. The event time (Item #1) may be displayed H, M or Sformat with six-digit resolution. The longest single-event timinginterval is 999,999 hours. The highest resolution is 0.2 µs. Theevent time may also be displayed in HH.MM.SS clock format with1 s resolution. The stopwatch display is updated during timingat a rate controlled by a gate time, up to 25/s. It is reset to zerowhen the next start pulse occurs. Accumulated time from multipleevents (Item #2) is also tracked and may be displayed up to999,999 hours.Inputs to the FR dual-channel signal conditioner can beproximity switches with PNP or NPN output, TTL or CMOS logic,magnetic pickups, contact closures, low-level outputs fromturbine flow meters down to 12 mV, and high-level AC line inputsup to 250 Vac.

Duration of a single wave shape can be measured by tying the A and B channels together. Timing Process DynamicsThe start and stop pulses used for timing can be generated by the dual relay board in a Laureate analog panel meter or digital counter. For instance, the start and stop pulse edges can be created as temperature passes two alarm setpoints, or as temperature cycles in a hysteresis control mode. Rate Based on 1 / TimeThe Extended stopwatch meter can be programmed to display highly accurate rate based on elapsed time. A pulse or switch closure can initiate timing, while another pulse or switch closure stops timing. The meter can be programmed with multipliers to display rate in appropriate engineering units, such as meters/sec, for any time duration.Replacing an Oscilloscope with a Laureate MeterAn oscilloscope is great for viewing and timing pulses in a lab. However, in fixed installations where digital timing accuracy and control outputs are required, a low-cost Laureate time interval meter will be the instrument of choice. Resolution to 0.2 µs is feasible.Instrumenting a Pulsed Laser SystemSome of the many possibilities in instrumenting a pulsed laser system with Laureate dual-channelcounters: elapsed time, number of pulses, pulse width, pulse separation, duty cycle, and pulse rep rate.Ordering GuideCreate a model number in this format: L50000FR, IPCMain Board L5 Standard Main Board, Green LEDsL6 Standard Main Board, Red LEDsL7 Extended Main Board, Green LEDsL8 Extended Main Board, Red LEDsNote: Use of the Extended Main Board makes this counter also suitable for A-B time interval,frequency, rate, period, square root of rate, up or down total, arithmetic functions, simultaneousrate and total, phase, duty cycle, batching, and custom curve linearization.Power0 Isolated 85-264 Vac1 Isolated 12-32 Vac or 10-48 VdcRelay Output (isolated) 0 None1 Two 8A Contact Relays2 Two 120 mA Solid State Relays3 Four 8A Contact Relays4 Four 120 mA Solid State RelaysAnalog Output (isolated) 0 None1 Single isolated 4-20 mA, 0-20 mA, 0-10V, -10 to +10V2 Dual isolated 4-20 mA, 0-20 mA, 0-10VDigital Interface (isolated) 0 None1 RS2322 RS485 (dual RJ11 connectors)4 RS485 Modbus (dual RJ45 connectors)5 USB6 USB-to-RS485 converter7 Ethernet8 Ethernet-to-RS485 converterInput Type FR Dual-Channel Pulse Input Signal ConditionerAdd-on Options CBL01RJ11-to-DB9 cable.
