Keyence LR-TB5000C LR-T Series Self-contained TOF Laser Sensor 5m M12 Connector Class 2

Keyence LR-TB5000C is a self-contained TOF (Time of Flight) laser distance sensor for long‑range detection up to 5 m, using a red 660 nm laser (Class 2). Detection range 60 mm to 5000 mm. Adjustable spot diameter (≤40 mm). Five selectable response times (1 ms to 1000 ms). Rugged zinc die‑cast metal case rated IP65/IP67, IO‑Link V1.1/COM2 (38.4 kbps) compatible, with NPN/PNP open‑collector and analog output (4‑20 mA / 0‑10 V). M12 4‑pin connector type. Suitable for material handling, assembly automation, packaging machinery and high‑precision positioning systems.

Applications:

• Long‑range presence detection on conveyor and sorting systems (up to 5 m)

• Distance measurement and positioning in automated assembly lines

• Object detection in packaging machinery and palletising systems

• Fill‑level monitoring and positioning in material handling equipment

• High‑speed counting and inspection in industrial automation

System Integration:

• This sensor belongs to the Keyence LR‑T series of self‑contained TOF laser sensors.

• M12 4‑pin male connector mates with standard industrial M12 female cables.

• IO‑Link V1.1/COM2 (38.4 kbps) is supported for parameter setting and diagnostics. Setup file can be downloaded from the KEYENCE website.

• I/O configurations can be selected during initial settings; independently isolate unused I/O wires.

• For detailed wiring diagrams, time charts, and setting methods, refer to the instruction manual.

• Optical installation guidance: for mirrored target surfaces, install the sensor at an angle to prevent specular reflection from entering the optical receiver.
