Honeywell TL-Q5MC1 Inductive Proximity Sensor

Product Description

The TL-Q5MC1 is a rectangular, unshielded inductive proximity sensor engineered for precise non-contact detection of ferrous metal targets. Manufactured by Omron, this sensor is designed for reliable operation in demanding industrial environments where dust, moisture, vibration, and temperature fluctuations are present.

With a compact square-type sensing head and robust IP67 enclosure, the TL-Q5MC1 provides stable detection performance, fast response, and long operational life. Its DC three-wire NPN open-collector output makes it compatible with a wide range of PLC and control system inputs used in factory automation and machinery control.

Key Functional Characteristics

The TL-Q5MC1 employs an unshielded sensing structure to achieve an extended detection range of up to 5 mm when detecting standard ferrous metal targets. This design allows greater sensing distance compared to shielded sensors, provided adequate clearance from surrounding metal surfaces is maintained.

A built-in red LED indicator provides clear visual confirmation of detection status, supporting fast installation, adjustment, and maintenance.
