Omron E2S-W22 1M Proximity Sensor
Omron E2S-W22 1M combines a compact square body with unshielded 2.5 mm sensing and a 0 to 1.9 mm setting distance. The sensor uses a DC 2-wire output with NC operation, a pre-wired 1 m cable, and a 12 to 24 VDC supply. Ferrous metal is the listed detectable object, with an iron 15 × 15 × 1 mm standard sensing object. Response frequency is 1 kHz minimum, leakage current is 0.8 mA max., control-output current is 3 to 50 mA, and differential travel is 10% max. of sensing distance. An orange operation indicator, output short-circuit protection, surge suppression, and IP67 protection are specified. The E2S-W22 1M is listed under compact square proximity sensors from Omron industrial sensing.

The Omron E2S-W22 1M Proximity Sensor uses a compact square, unshielded sensing body with a 2.5 mm sensing distance and a 0 to 1.9 mm setting distance. It provides a DC 2-wire output with NC operation through a pre-wired 1 m cable and operates from 12 to 24 VDC. Ferrous metal is the specified detectable object, with an iron 15 × 15 × 1 mm standard sensing object. Response frequency is 1 kHz minimum, leakage current is 0.8 mA max., control-output current is 3 to 50 mA, and differential travel is 10% max. of sensing distance. An orange operation indicator is provided, while output short-circuit protection and surge suppression are included in the listed protection functions.
Operating conditions for the E2S-W22 span -25 to 70°C, with storage from -40 to 85°C. Humidity is specified at 35% to 90% during operation and 35% to 95% during storage. Polyarylate resin is listed as the construction material, and the sensor carries IP67 protection. The 1 m cable is combined with DC 2-wire NC switching and the stated 2.5 mm sensing range. For another E2S model retaining 2.5 mm sensing, NC operation, and a 1 m cable but using a DC 3-wire NPN output, see E2S-W24 1M.
