Omron E2S-W23 1M Proximity Sensor
Omron E2S-W23 1M is a compact 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 NPN output with NO operation and a pre-wired 1 m cable. Power-supply voltage is 12 to 24 VDC. Ferrous metal is the specified detectable object, with an iron 15 × 15 × 1 mm standard sensing object. The sensor provides a 1 kHz minimum response frequency, 13 mA max. current consumption at 24 VDC with no load, and 50 mA max. control-output load current at 30 VDC. An orange operation indicator and IP67 protection are specified. The E2S-W23 belongs to the Proximity sensor range from Omron sensor products.

The Omron E2S-W23 1M Proximity Sensor is a compact square, unshielded sensor with a 2.5 mm sensing distance and a 0 to 1.9 mm setting distance. Its electrical configuration is DC 3-wire NPN with NO operation, connected through a pre-wired 1 m cable. Power-supply voltage is 12 to 24 VDC. Ferrous metal is the specified detectable object, and the standard sensing object is iron measuring 15 × 15 × 1 mm. Differential travel is 10% max. of sensing distance, while response frequency is 1 kHz minimum. Current consumption is 13 mA max. at 24 VDC with no load, and the control-output load current is 50 mA max. at 30 VDC. An orange operation indicator is included.
Protection includes power-supply reverse-polarity protection and a surge suppressor. Operating temperature is specified from -25 to 70°C and storage from -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 listed for the case and degree of protection is IP67. For a closely matched Q-series model carrying the same 2.5 mm sensing distance, DC 3-wire NPN output, NO operation, 12 to 24 VDC supply, and pre-wired 1 m cable, see E2S-Q23 1M.
