Product Description

The Keyence LR-TB2000CL is a compact, self-contained Time-of-Flight (TOF) laser sensor designed for precise distance measurement in industrial automation applications. It features a cable with an M12 connector, offering a detection range from 60 mm to 2000 mm. The sensor utilizes a red laser (660 nm) and provides a spot diameter of approximately 4 mm. With selectable response times of 2 ms, 20 ms, 50 ms, 200 ms, and 2000 ms, it offers flexibility to meet various application needs. The LR-TB2000CL supports both NPN and PNP open collector control outputs and features a mutual interference prevention function, allowing up to four units to operate simultaneously when alternate frequencies are set. It boasts robust environmental resistance with an IP65/IP67 rating, making it suitable for harsh industrial environments. This model is part of the LR-T series and is designed for applications requiring high precision and reliability.
