Sick WSE12-3P2431 Photoelectric Sensor

The Sick WSE12-3P2431 Photoelectric Sensor is built around a through-beam sensing system that delivers a robust sensing range of 0 m to 15 m, with a maximum capability of up to 20 m. Its visible red LED light operates at a wavelength of 640 nm and produces a focused Ø 220 mm light spot at 15 m, ensuring precise object detection even at extended distances. Fine-tuning is made simple with a 5-turn potentiometer, giving installers full control over sensitivity adjustments to match specific industrial setups.

With a supply voltage range of 10 V to 30 V DC and a minimal current consumption of ≤ 30 mA, the sensor is both energy-efficient and compatible with most automation power systems. It offers a complementary PNP digital output, along with light/dark switching functionality, making it highly adaptable to a variety of logic circuits. Built for speed, the response time is ≤ 330 µs and the switching frequency reaches 1,500 Hz, enabling fast detection in dynamic applications. Housed in a compact rectangular metal enclosure (15.6 mm × 48.5 mm × 42 mm) with an M12, 4-pin male connector, this sensor is ready for harsh factory environments. It holds IP66, IP67, and IP69K protection ratings, making it suitable for use in dusty, wet, or washdown zones. Trusted by engineers for its reliability and precision, the WSE12-3P2431 is a go-to sensor in high-demand industrial facilities. .

The Sick WL4S-3F2130 Photoelectric Sensor is ideal for compact machines, miniature conveyors, and robotic arms where space is limited and precision is essential. It accurately detects the presence or position of components like bottles, labels, or caps, even in low-reflective environments.

This sensor is especially useful in industries such as electronics, pharmaceuticals, and food processing, where quick and reliable object detection is critical. Maintenance engineers appreciate its simple setup, while engineering students find it a perfect example of how advanced sensors streamline modern automation systems. Every feature is designed to ensure smooth, error-free operation across various applications.
