SICK WL12-3P2461 Photoelectric Sensor - High Reliability and Easy Setup

sick WL12-3P2461

Selling Points

1High immunity to ambient light and crosstalk ensures fewer false readings and less downtime.
2Quick and easy setup due to highly visible PinPoint LED light spot.
3Rugged metal housing (optional Teflon coating) resists high-pressure cleaning and requires fewer maintenance costs.
4Increased reliability in harsh wash-down environments with IP66, IP67, and IP69K ratings.
5Easy installation using SICK accessories for seamless integration.
