LB4000 Ultrasonic Displacement Sensor with NPN/PNP Switching Output
Product Description
LB4000 Ultrasonic Displacement Sensor with Switching Output
The MANORSHI LB4000 series is an ultrasonic displacement sensor with a detection range of 200–4000 mm. Its NPN and PNP switching output options support object presence detection and position monitoring across an operating range of up to four meters.
Teach-in configuration allows switching points to be set according to target position. Built-in temperature drift compensation supports measurement consistency. Red and green LEDs display target detection and teach-in status, while IP67 protection and a 5-pin M12 connector support industrial installation.
