ifm electronic KT5101 Series Push Button Switch, Panel, 22 mm Cutout Green, SPST, IP65, IP67, IP69K

This range of panel mount capacitive push buttons from IFM offers a contactless solution to applications where a traditional mechanical push button may have been used. The contactless Push buttons are designed to meet an IP69K ingress protection rating and a wide temperature range of -40 °C to 85 °C making them highly versatile and suitable for use in industrial environments. Due to the capacitive sensing technology no physical contact or mechanical pressure is needed to actuate the button which reduces the wear and ultimately decreases maintenance cost for the end user.

Easy installation with M22 thread
IP69K ingress protection rating
Operating temperature of -40 °C to 85 °C
Wear free button actuation
M12 connector versions available

Actuated by sensors using patented Field Effect Technology which converts the touch of the operators hand into an electrical output. The two sensors have to be touched within 0.2 seconds of each other and can differentiate between a person's hand and most solid objects/substances, as well as resistance to accidental actuation via clothing, fluid, splashes etc.,There are built in diagnostic safeguards for power-up protection, foreign object intervention and film/deposit interference which all result in LED indication.
