  • Conducting and non-conducting sensing

  • Non-contact sensing

Proxistor proximity switches.

The adjustable sensitivity of these capacitive proximity switches allows them to be tuned to differentiate between various materials or cope with different installations. Applications include non-invasive content detection through non-metallic containers; level detection or flow indication of solids or liquids; bottle counting with content detection; packaging counting; band loop controlling or breakage indication; use as non-contact switches; and wire-winding break detection. There are fixed lead or connector versions with an operating range of -30 to 100°C. They offer reverse polarity and short circuit protection. All switches are available as normally open or closed.

0200ee2Voltage selector. The SE 1022 voltage selector switch eliminates unnecessary circuitry and components that are otherwise required for gear to be used in international service. Applications include computers and peripherals, power supply circuits, medical equipment and electronic data communication equipment. Electrically, the voltage selector is a double-pole, double-throw (DPDT) slide switch rated for service up to 10A at 125 VAC and 5A at 250 VAC. It can be clip- or bolt-mounted.

0200ee6Tiny series.Recognizing that surface mount devices are subject to more stringent constraints of temperature, sealing, solderability and space savings, the TP Series pushbutton switches, the TL Series toggle switches, the TR Series rocker switches, and the TG Series slide switches incorporate the latest advances in this technology. The company also offers an LED indicator in a compatible package size. Numerous momentary and maintained electrical configurations are available in these single pole models that also feature optional positioning pins. Their small size is exemplified by a toggle selection that measures just 0.218-in. w x 0.378-in. l x 0.397-in. deep. Ratings are 0.4 VA at 20V max with up to 60,000 cycles of electrical life.
