Omron E2S-W25 1M Proximity Sensor
Omron E2S-W25 1M is a square proximity sensor with an unshielded structure, 2.5 mm sensing distance, and 0 to 1.9 mm setting distance. It uses a DC 3-wire PNP output with NO operation and a pre-wired 1 m cable. The power-supply range is 12 to 24 VDC. Ferrous metal is specified as the detectable object, with an iron 15 × 15 × 1 mm standard sensing object. Response frequency is 1 kHz minimum, current consumption is 13 mA max. at 24 VDC with no load, and control-output load current is 50 mA max. at 30 VDC. An orange operation indicator and IP67 protection are specified. The E2S-W25 belongs to the Proximity sensor family from Omron sensing products.

The Omron E2S-W25 1M Proximity Sensor uses a compact square, unshielded format with a 2.5 mm sensing distance and a 0 to 1.9 mm setting distance. Its output is DC 3-wire PNP with NO operation, and connection is through a pre-wired 1 m cable. Supply voltage is 12 to 24 VDC. Ferrous metal is specified as the detectable object, with an iron 15 × 15 × 1 mm standard sensing object. Differential travel is 10% max. of sensing distance and response frequency is 1 kHz minimum. Current consumption is 13 mA max. at 24 VDC with no load, while control-output load current is 50 mA max. at 30 VDC. An orange operation indicator is provided.
Protection includes power-supply reverse-polarity protection and a surge suppressor. Operating temperature is -25 to 70°C and storage temperature is -40 to 85°C without icing or condensation. Operating humidity is 35% to 90%, while storage humidity is 35% to 95% without condensation. Polyarylate resin is specified for the case, and degree of protection is IP67. For a closely matched E2S compact square model with the same PNP NO output, 2.5 mm sensing distance, 12 to 24 VDC supply, and 1 m connection, see E2S-Q25 1M.
