The SICK WL2S-2N1330 (Part No. 1064595) is a high-precision, miniature photoelectric sensor engineered for demanding industrial applications where space is limited and rapid, reliable detection is essential.

Employing a retro-reflective design with autocollimation, it offers flexible sensing capabilities—starting from 0 m without requiring a reflector, yet extending its full reach up to 1.2 m when used with a suitable reflector. This makes it ideal for a broad range of installations, from compact assembly lines to longer-range detection tasks.

Illumination is provided by a visible PinPoint red LED at 640 nm, generating a focused Ø 12 mm light spot at 250 mm, which simplifies alignment and delivers consistent detection accuracy even for small or subtle targets.

The WL2S-2N1330 features a fast NPN light-switching output, turning on when the light beam is unobstructed. With an impressive response time of less than 0.5 ms and a switching frequency reaching 1,000 Hz, this sensor meets the high-speed requirements of modern automation systems—ensuring minimal latency in detection-critical processes.
