Single-button switches, available in 1/2-, 3/4-, and 11/4-inches, control the current level from microamps to amps and activate dc or ac systems. With no moving parts, the switches have an operational life of up to 50 million cycles. Hermetically sealed, they are impervious to chemicals and temperatures operating in the range of -40 to 125C. They are suited for use in medical applications and are available with or without lighted faces and in a wide array of colorful housings with illumination.

EMIshielding gasket installation is easier with Easy-Peel release liner, featuring an easy-to-grasp design. Available on all FoamTite EMI gaskets, the liner is extra-wide, allowing for faster removal of the liner from the adhesive strip and increasing the ease of product placement. The low-compression force EMI gaskets are offered in a range of performance levels from 50 to 100 dB.

Model 7600 Snub-Nose DeltaTM photoelectric sensor features cable placement that allows for storage in tight spaces without obstructing the LED visibility. Measuring 18 mm wide, the 7600 fits into a standard 18 mm cutout and may be ordered with thru-beam, polar, retro- or diffuse-sensing options and FET, NPN, or relay outputs. It operates on ac or dc voltage with either cable or connector, and can be customized to meet special requirements.

PicoDotTM Class II convergent laser sensor measures 40 x 45 x 12.7 mm. A precise convergent point size of 0.25 mm at its focal distance makes this laser suitable for applications such as semiconductor wafer mapping, miniature parts detection, and connector-pin counting. An overall sensing distance of 50 to 115 mm exists with a focal distance of 100 mm. Fixed-field sensing ensures that any object beyond the maximum sensing distance is ignored. A response time of 0.2 msec allows the sensor to work effectively in high-speed applications such as lead or pin counting. The sensor operates from 10 to 30V dc and is available with either NPN (sinking) or PNP (sourcing) output.

RUBRGLASTM transparent seals fit snugly around the unit's bezel to protect it from harmful contaminants such as lubricants, rain, dust, dirt, and washdowns. Their perimeter-sealing rib seals the panel cut-out in which the component is mounted, protecting the internal electronic system from the hazardous environment. Units are available for popular switches/circuit breakers from Carlingswitch, Arrow-Hart, Airpax, Cutler Hammer, and Potter & Brumfield's W33 Series. Applications include use in boat control panels, portable test equipment, communications equipment, floor/carpet cleaning equipment, and medical instruments.
