Spring-return roller lever, 1NC+1NO, IP66/IP67
The XCPR2121P20 is a general duty limit switch from the Osisense XC range, with a spring-return roller lever plunger actuated by lateral approach in one direction. It carries one normally-closed and one normally-open contact pair, giving you a positive-break NC for safety circuits and a NO for status feedback. Rated IP66 and IP67 per IEC 60529, the switch body and actuator seal against hose-directed water and temporary immersion — suitable for washdown zones and outdoor enclosures where the switch sees direct spray or standing water.
Standards compliance and mounting
Vibration resistance is 25 GN at 10–500 Hz (IEC 60068-2-6) and shock resistance is 50 GN for 11 ms (IEC 60068-2-27). Mounting is by the body, with screw-clamp terminals accepting 1 x 0.34 mm² up to 2 x 1.5 mm².
