LU Series
Capacitive Proximity Sensor
LU series inductive proximity sensor is a slot shape proximity sensor with 3-4mm detection distance , and 3-4mm setting distance. LU series proximity sensors have the advantages of cost-effective, simple to operate, long life and high reliability, and can adapt to complex working environments. LU series proximity sensors are equipped with power reverse protection, short-circuit protection, etc., and can be directly connected with PLC device. The operating status of the sensor can be directly observed through the red LED, LU series proximity sensors are IP67 protected (IEC standard). Depending on the control output, proximity sensors can be divided into NPN type (N type), PNP type (P type), AC type (A type), and DC type (D type).
