SICK WL27-3R2631 Overview
Photoelectric reflex switch WL27-3R2631 red light, relay, rectangular plug, 6 pins, time delay
SICK WL27-3R2631 Description
- 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
- 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
