Omron E2A-S08KN04-M1-B1 Proximity Sensor
Omron E2A-S08KN04-M1-B1 combines an M8 unshielded inductive sensing head with a 4 mm sensing distance, 0 to 3.2 mm setting distance, and short-body construction. It uses a PNP output with NO operation through an M12 connector and works from a 12 to 24 VDC supply. Ferrous metal is the specified detectable object, with a 12 × 12 × 1 mm standard sensing object. Response frequency is 1,000 Hz, current consumption is 10 mA max., and differential travel is 10% max. of sensing distance. A yellow LED provides operation indication, while stainless steel construction and IP67 protection are specified. The E2A-S08KN04-M1-B1 is listed under M8 proximity sensors from Omron industrial sensing products.
