Technical Overview
The Omron TL-Q5MC1 2M is an unshielded rectangular inductive proximity sensor for detecting ferrous targets at a nominal 5 mm sensing distance. It uses a DC three-wire NPN open-collector normally open output, a 12 to 24 VDC rated supply and a 2 m pre-wired cable. OMRON specifies IP67 protection and operation from -25 to 70 °C. OMRON's exact TL-Q5MC1 2M product page reports the item as currently sold and a standard-stock model, updated 2026-09-11.

Suggested applications
Engineering suggestions require suitability checks for your installation.
1. Ferrous target position sensing
A machine may need a discrete input when a steel target reaches a defined position.
Potential use
The NPN normally open output can signal a compatible DC control input as the target enters the sensing zone; verify mounting gap and input load.

2. Metal part detection on a conveyor
A material-handling station may need to detect a passing ferrous component without contact.
Potential use
Install the sensor with a suitable target within its 0 to 4 mm set distance and route the 2 m cable to a compatible input.
