Omron TL-N20MD2 2M is an unshielded 20 mm DC 2-wire NC proximity sensor with a 2 m cable and IP67 protection.
The Omron TL-N20MD2 2M is an unshielded rectangular inductive proximity sensor with a 20 mm nominal sensing distance, DC 2-wire normally-closed output and a 2 m pre-wired cable. It operates from 10 to 30 VDC (rated 12 to 24 VDC) and detects ferrous metal targets; non-ferrous targets reduce sensing range. The sensing head measures 40 x 41 x 53 mm. Omron lists IEC IP67 protection and its internal oil-proof standard. Omron listed this exact model as selling and standard-stock on 2026-10-05, with stock indicator －.

Engineering suggestions require suitability checks for your installation.
The sensor detects ferrous metal at a nominal 20 mm distance.
Position the ferrous target within the 0 to 16 mm setting distance and verify detection with its actual size and orientation.
The NC DC 2-wire output can signal a machine part entering the sensing zone.
Connect to a compatible 10 to 30 VDC circuit, account for sensor leakage current, and maintain Omron clearance recommendations.
