Product Description

The Keyence LR-TB2000C is a self-contained Time-of-Flight (TOF) laser displacement sensor designed for precise distance measurement in industrial automation applications. Utilizing a red laser (660 nm) light source, it offers a detection range from 60 mm to 5,000 mm with a spot diameter that varies with distance. The sensor features a Class 1 laser classification, ensuring safety in operation. It supports IO-Link v1.1/COM2 communication, enabling seamless integration into smart factory environments. The LR-TB2000C is housed in a compact, robust casing with an IP65/IP67 rating, making it suitable for deployment in harsh industrial settings.​
