TopWorx™ 52M is a low profile, dry contact, proximity sensor with a 316L sensing face in an industry standard 12mm package. The 52M does not require power to operate and is polarity insensitive with zero need to specify NPN or PNP circuits and maintains the ability to be a plug-and-play replacement for inductive proximity sensors. Also, the 52M can handle a wide current range from 5mA to 2A @ 24VDC and a wide temperature range from -40°F to 212°F (-40°C to 100°C).
