WLL11G-2B2531P04_SICK_PRODUCT_吉林易择科技技术发展有限公司

The SICK WLL11G-2B2531P04 is a compact retro-reflective photoelectric sensor featuring autocollimation optics, enabling object detection without a reflector from zero to four meters. It emits a visible red light via an LED, ensures high-precision sensing with a small light spot, and supports both PNP and NPN outputs with selectable light/dark switching. The device incorporates an 11-turn potentiometer for fine adjustment, rugged ABS housing rated IP66/IP67/IP69K, and robust electrical protection, making it ideal for detecting transparent objects in industrial environments
