Telemecanique XCKN2902P20 Limit Switch 2NC Plastic Roller Plunger M20

The Telemecanique XCKN2902P20 is an XC Standard limit switch with a plastic spring return roller plunger head and two NC snap action contacts. The plastic body is rated IP65 and takes a single M20 x 1.5 cable gland entry. Both NC contacts have positive opening operation, so the switch can be used in a safety interlock circuit.
