Omron TL-W3MB1 2M Proximity Sensor
Omron TL-W3MB1 is a flat inductive, unshielded proximity sensor with a 3 mm sensing distance and a 0 to 2.4 mm setting distance. Its output is DC 3-wire PNP with NO operation, using a pre-wired 2 m cable and a 12 to 24 VDC supply. Ferrous metal is the specified detectable object, with an iron 12 × 12 × 1 mm standard sensing object. Response frequency is 600 Hz minimum, current consumption is 15 mA max. at 24 VDC, and differential travel is 10% max. of sensing distance. A red detection indicator, reverse-polarity protection, surge suppression, and IP67 protection are specified. The TL-W3MB1 is listed under flat proximity sensors from Omron flat sensing products.

The Omron TL-W3MB1 2M Proximity Sensor is a flat inductive, unshielded model with a 3 mm sensing distance and a 0 to 2.4 mm setting distance. Its electrical configuration is DC 3-wire PNP with NO operation, using a pre-wired 2 m cable and a 12 to 24 VDC supply. Ferrous metal is listed as the detectable object, with an iron 12 × 12 × 1 mm standard sensing object. Response frequency is 600 Hz minimum, current consumption is 15 mA max. at 24 VDC with no load, and differential travel is 10% max. of sensing distance. A red detection indicator is provided, while reverse-polarity protection and surge suppression form the listed protection circuit.
Operating and storage temperature is -25 to 70°C without icing or condensation, with humidity from 35% to 95%. Temperature influence is ±10% max. of sensing distance at 23°C over the stated temperature range. Insulation resistance is 50 MΩ min. at 500 VDC, dielectric strength is 1,000 VAC for 1 minute, and voltage influence is ±2.5% max. within rated voltage ±10%. The model is rated IP67. For another TL-W sensor keeping the 3 mm sensing distance and 2 m pre-wired connection but using NPN output with NC operation, see TL-W3MC2 2M.
