Technical Overview
The Omron TL-Q5MD2 2M is an unshielded rectangular inductive proximity sensor with a 5 mm nominal sensing distance. Its DC two-wire output is normally closed, 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. Normally closed metal target monitoring
A machine may need an input that changes state when a ferrous part leaves a monitored location.
Potential use
Use the D2 normally closed switching mode in a compatible two-wire DC input circuit and check the specified load and leakage current.

DC 2-wire
Normally closed
IP67
2. Machine travel limit sensing
A fixture may need a compact inductive device to monitor movement of a metal component.
Potential use
Position a ferrous target within the 0 to 4 mm set distance and verify the input current range before commissioning.
