SICK WTB4-3N1362 Overview
Photoelectric Proximity switch WTB4-3N mm BGS, NPN, Teach-In, 2 m cable, 3 wire
SICK WTB4-3N1362 Description
- Intensive light spot thanks to PinPoint technology for precise detection with a high level of repeat accuracy
- Sensor with IR light on request
- Scanning distance 4 - 150 mm
- BGS sensor available with linear laser-like light spot
- Adjustment either via teach-in button, 5-speed potentiometer, cable or IO-Link.
-
Second emitter LED for suppression of critical reflective backgrounds
Your benefits
- Reliable detection of objects of all types
- Low-cost integration in a machine as, unlike other types, the WTB4-3 can be integrated optimally in cramped installation conditions so it is closer to the process
- The WTB4-3 enables smart machine design as reliable object detection is possible in the tightest space situations and with close-by critical backgrounds.
- Reliable detection thanks to best-in-class background suppression and high resistance to extraneous light
- Robust mounting due to M3 threaded metal sockets for a long service life.
