Technical Overview
The Omron TL-Q5MD1 2M is an unshielded rectangular inductive proximity sensor with a 5 mm nominal sensing distance. Its DC two-wire output is normally open, with a 12 to 24 VDC rated supply and a 2 m pre-wired cable. OMRON specifies IP67 protection, an operating range of -25 to 70 °C and a 3 to 100 mA load-current range; current supply status was not explicitly confirmed.

Suggested applications
Engineering suggestions require suitability checks for your installation.
1. Two-wire machine state sensing
A control system may need to detect a ferrous target without adding a separate three-wire sensor output.
Potential use
The DC two-wire normally open output can be placed in a compatible series input circuit; verify load current and leakage requirements.

2. Metal target counting
A compact station may count steel parts passing near a fixed sensing point.
Potential use
Use the 500 Hz response capability within the manufacturer's specified target and mounting conditions and check the input circuit load.
