Photoelectric Through-Beam Sensor GSE10-N1221 SICK 40 m NPN 2m Cable
Overview:
The GSE10-N1221 from SICK is a through-beam photoelectric sensor from the G10 series, consisting of separate sender and receiver units. It offers a maximum sensing distance of 40 m (recommended 35 m), NPN output, 850 nm infrared LED, and a 2 m cable. With its compact design, fast response time (≤ 500 µs), and switching frequency of 1,000 Hz, the sensor is ideal for high-speed conveyor systems, logistics, automated warehouses, and industrial production lines.
The sensor features an IP67 protection rating and a wide operating temperature range (-30 °C to +60 °C), making it suitable for dusty, humid, and high-vibration industrial environments.
Product Overview of the Photoelectric Through-Beam Sensor
The GSE10-N1221 operates on the through-beam principle. The sender and receiver are mounted opposite each other. When an object interrupts the infrared light beam between the two units, the sensor output changes state to indicate object detection.
Thanks to its separate sender-receiver design, the GSE10-N1221 provides very high excess gain and excellent immunity to interference, delivering stable detection over long distances. It significantly outperforms retro-reflective and diffuse sensors in range and reliability. The sensor is equipped with a 270° sensitivity adjustment potentiometer, allowing easy optimization for different installation conditions.
With its compact dimensions (20 × 50 × 39 mm), robust ABS/PMMA housing, and strong resistance to vibration, the GSE10-N1221 is a reliable solution for demanding industrial applications requiring high accuracy and durability.
