Touch sensors and push buttons

Sensor	Housing	Electrical design	Sensing range	Operating principle	Points to consider
KT50	Ø100 mm	DC PNP	normally open	dynamic static	Non-contact switching without pressure LEDs for visual feedback Oil-resistant, impact and scratch resistant Surround available in different colours Simple installation on walls or rear panels
KT5 / KT6	M22	DC PNP DC NPN	• normally open • normally closed	bistable dynamic static parameterisable	Ergonomic working by softly touching the sensor Start-up delay prevents unintentional switching Plant condition indicated via RGB LEDs Various setting options such as colour, NO/NC or triggering via IO-Link Adjustable brightness and sensitivity in wet environments or when operators wear gloves
