Sealed switches guard against ESD

S Series miniature toggle, rocker, and pushbutton switches have ratings that satisfy dry circuits as well as moderate power applications while protecting circuitry against electrostatic discharge (ESD). UL-recognized for 4A, 125V ac or 2A, 250V ac applications, all switch types are available with a selection of actuator configurations and PC-board mounting styles. Other options include gold-plated contacts, tin-plated terminals, and crimped mounting bracket terminals for self-fixturing during assembly and soldering. For electrostatic protection, actuators are made from high-insulation plastics. Insulating heatshrink tubing and spacing pads that fit between the switch body and PC board provide terminals with additional ESD protection. Pricing for a right-angle-mounting toggle switch is $2.45 each in 1000-piece volumes. APEM Components, http://www.apem.com

Solid-state relays make assembly easy

Designed with the OEM assembler in mind, the new Quick Mount line of solid-state relays replaces screw terminals with 1/4-in quick connects. The relay package is 2x2x1 inch and has a molded-in heat-transfer plate to improve thermal dissipation. The NIF Series of latching relays provides a flip-flop function. Each time a control voltage is applied, the output changes state and latches. Operating voltages of 24, 120, and 230V ac, 50/60 Hz, are standard. The triac output can be normally open or normally closed; ratings are 6, 10, or 20A steady (60, 100, or 200A inrush) with zero voltage or random-on switching. SSAC Inc., http://www.ssac.com

Relay does it all

Omron's G3VM line of MOSFET relays just debuted at the Electronics Industries Forum of New England this spring. This flexible line is available in 4-, 6-, and 8-pin configurations and in industry standard surface-mount and through-hole mounting configurations. Relay specs include output voltages up to 350V dc, 50-mA input, -350 to 350V output load voltage, and maximum output ON resistance of 35{OMEGA}. Plus, the relays handle a variety of continuous load current connections--ac, dc series, and dc parallel--at 120, 150, and 200 mA. Pricing starts at $1.80 each in quantities of 1,000.

High capacity, long life in a pushbutton

SCB Series panel-mount pushbutton switches offer high capacity and long life with the precise actuation and reliability of a snap switch, say NKK engineers. This feature combination suits heavy industrial and other applications requiring precision switching and high reliability. Long-life models provide a guaranteed minimum of 5 million operations and are rated at 10A and 1/3 hp at 125 or 250V ac. High-capacity types deliver at least 1 million operations and are rated at 15A and 1/2 hp at 125 or 250V ac. Both versions are UL recognized and CSA certified. Termination choices include 0.187-in quick connect, 0.250-in quick connect, solder lug, and screw types; and three cap diameters are available in eight colors. NKK Switches, FAX (602) 998-1435.

Automotive relay handles flasher loads

A new power relay from Fujitsu handles the high inrush currents of automotive flasher lamps used in turn signals and emergency flashers. Contacts of silver-indium-tin oxide let the relay provide more than 4 million operations at 16V dc, 28A inrush to meet the flasher lamps' long-life requirements. The unit itself measures 15.5x12.1x13.7 mm and weighs 6g. The FBR51-WR can also be used for any low-voltage dc lamp load, as outlined in the part's spec. Coil power is rated at 600 mW, and the part is available in 9, 10, and 12V dc coil ratings. Pricing is $1.19 each in 1000-piece quantities. Fujitsu Takamisawa America, http://www.fujitsufta.com

Sensitive relay offers low thermal EMF

With thermal EMF as low as 0.15 muV, NAiS(R) brand TXS polarized relays suit high-accuracy test and measurement applications. The 2 Form C devices measure 15x7.4x8.2 mm and consume only 50 mW, which extends battery life in portable test equipment. In addition, they eliminate the need for the IC drivers conventional relays require. Models are available for 1.5 to 24V dc operation with single-side-stable, one-coil, and two-coil latching operating functions. Nominal operating power for one-coil latching is as low as 35 mW. Switching capability with resistive load is 1A, 30V dc, maximum switching voltage is 110V dc, maximum switching current is 1A, and minimum switching capability is 10 muA, 10 mV dc. At 20C, operate and release times are 5 msec max. TXS2 12V relays cost $2.41 each in 1,000-piece quantities. Aromat Corp., http://www.aromat.com

DIP rotary switch saves board space

CD Series ultra-miniature DIP coded rotary switches from C&K Components withstand surface-mount process temperatures and are sealed for immersion cleaning. The 8-mm square units protrude 4 mm from a PC board and come with surface-mount, through-hold, or right-angle through-hole terminals. Features include a crisp detent, O-ring actuator seal, and flush or extended actuators. Typical life is 20,000 position changes; contacts are gold plated, and terminals are tin plated. Models come in 10-position BCD and 16-position hexadecimal with real and complement codes available. The devices suit applications that require programming, including communications products, peripherals, computers, and industrial controls. Prices start at $2.40 each in 1000-piece volumes.

Reed relay for high frequencies

Capable of passing up to 1-GHz signals with minimal distortion, ATE Series reed relays from CP Clare suit such applications as IC tester load boards, high-frequency communications products, and mixed-signal testers. Typical operating time is 0.5 msec--faster than most electromechanical armature-style relays. High-speed switching results in faster test times, increasing throughput and decreasing testing costs. Magnetic shielding allows for high-density packing, which custom load boards require. The relays have a typical life expectancy of 500 million operations and a stable contact resistance of 150 m{OMEGA}.They also feature insulation resistance between all isolated pins of 10and a dielectric strength ¹¹{OMEGA} of 1,000V dc/peak ac between switch to coil and shield. Eight different package styles meet most custom designs for existing footprints. Price is $2 each in 10,000-piece quantities. Div., CP Clare Corp., Reed Relay Products http://www.cpclare.com
