Photoelectric reflex switch WL27-3S3731 red light, relay, pigtail with rectangular plug, 7 pins

High scanning range, high operating reserves
Faster alignment with red light
Reliable operation in industrial environments and when devices are mounted opposite one another
Front screen heating, time functions
Operating temperature: -40 C - +60 C
UL approval

Your benefits

Less downtime plus resistance to contamination due to high operating reserves
Flexible usage due to extended functionality e.g. time functions
Extremely vibration resistant and therefore largely independent of ambient conditions
For use at temperatures as low as 40 C
Highly stable housing due to offset fixing holes
