Keyence LR-TB2000C Self-contained TOF Laser Sensor 2m M12 Class 2

Keyence LR-T series LR‑TB2000C is a self-contained TOF (Time of Flight) laser sensor designed for stable detection of a wide range of targets regardless of colour, surface finish or material. 60 to 2000 mm detection range with visible red laser light source (660 nm, Class 2). Equipped with M12 connector cable (5‑core) for industrial connectivity. 5 selectable response times from 1 ms to 1000 ms. NPN/PNP open‑collector output selectable, IO‑Link V1.1/COM2 (38.4 kbps) support, and IP65/IP67 zinc die‑cast housing.

Applications:

• Part presence detection on conveyor systems

• Height verification and dimension measurement in automated assembly

• Small part detection and positioning for pick‑and‑place

• Object detection in packaging, automotive and electronics manufacturing

• Distance‑based detection where target reflectivity may vary
