Omron E2A-M12KS04-M1-B1 Proximity Sensor
Omron E2A-M12KS04-M1-B1 uses an M12 shielded inductive sensing body with a 4 mm sensing distance, a 0 to 3.2 mm setting distance, and short-body construction. It provides a PNP output with NO operation through an M12 connector and operates from 12 to 24 VDC. 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 operation LED and IP67 protection are specified. The E2A-M12KS04-M1-B1 is listed among M12 proximity sensors from Omron industrial sensing products.
