Product Description

The Keyence LR-ZB250CP is a self-contained CMOS laser sensor designed for precise distance measurement in industrial automation applications. It features a compact rectangular form factor with an M8 4-pin connector, offering a detection range from 35 mm to 250 mm. The sensor utilizes a red laser (660 nm) and provides a spot size of approximately 2.4 × 1.2 mm at 250 mm. With selectable response times of 1.5 ms, 10 ms, and 50 ms, it offers flexibility to meet various application needs. The LR-ZB250CP is equipped with a 3-digit 7-segment display for easy monitoring and supports PNP open collector control outputs. It boasts robust environmental resistance with an IP68/IP69K rating, making it suitable for harsh industrial environments. Please note that this model has been discontinued; the recommended replacement is the LR-ZB250AP sensor.​
