Engineered for maximum accuracy over long distances, the Sick WSE4SL-3P2237 is a through-beam photoelectric sensor that offers a sensing range of up to 60 meters. Its core advantage lies in its laser light source with a wavelength of 650 nm, which generates a highly focused 1 mm light spot at 500 mm. This sharp beam ensures precise detection even of small or fast-moving objects, making it suitable for complex industrial setups. The sensor incorporates a simple teach-in button for easy calibration and setup in the field.
Built with robust industrial-grade materials like Novodur plastic housing and a PMMA front screen, the WSE4SL-3P2237 is rated for IP66 and IP67 protection. It withstands harsh environments, offering reliable operation between –10 °C and +50 °C. The unit supports PNP digital output and both light/dark switching modes. Its supply voltage range of 10 V DC to 30 V DC, low current consumption of 30 mA, and fast response time of ≤ 0.5 ms make it highly compatible with PLC-controlled systems. With a 1,000 Hz switching frequency, it ensures seamless integration into high-speed production lines.
The sensor's compact size (12.2 mm × 41.8 mm × 17.3 mm) and M12 4-pin male connector simplify mounting and maintenance. Trusted by OEMs and factory automation specialists worldwide, the Sick WSE4SL-3P2237 Photoelectric Sensor offers unbeatable precision, durability, and ease of use.
