SICK WTB27-3P3741 Overview
Photoelectric proximity switch WTB27-3P3741 red light, PNP, pigtail with rectangular plug, 7 pins
SICK WTB27-3P3741 Description
- Precise background suppression with no scanning distance drift
- PinPoint technology: light-intensive red emitter LED with homogenous light spot
- Reliable operation in industrial environments - with ambient light, optical reflections and when devices are mounted opposite one another
- Scanning distance setting with potentiometer or easy teach-in
- Operating temperature: -40 C +60 C
- UL approval
- Very precise detection with no scanning distance drift in case of vibrations
- PinPoint technology can replace laser photoelectric proximity sensors in some applications, eliminating the need for laser safety measures, and the service life of the PinPoint LED is double that of conventional laser diodes
- Less downtime due to ASIC chip technology by SICK
- Reliable in operation with ambient light, optical reflections, and when devices are mounted opposite one another
- Reduces setup costs e.g. in case of format adjustment by IO-Link sensor communication interface
- Highly stable housing due to offset fixing holes
- For use at temperatures as low as 40 C
