WL4S-3P3132_SICK_PRODUCT_吉林易择科技技术发展有限公司

The SICK WL4S-3P3132 is a compact retro-reflective photoelectric sensor featuring autocollimation optics so it can detect objects without the need for a reflector. It uses a visible red PinPoint LED light source and includes a single teach-in button for easy setup. The sensor offers fast, light-only switching (PNP), operates over a wide supply range, and delivers high-speed response—all within a rugged, IP67-protected plastic housing suitable for industrial environments.
