Omron E2A-M12KS04-M1-B2 Proximity Sensor
Omron E2A-M12KS04-M1-B2 is an M12 shielded inductive proximity sensor with a 4 mm sensing distance, 0 to 3.2 mm setting distance, and short-body construction. It uses a PNP output with NC 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 indicator, electrical protection functions, and IP67 protection are specified. The E2A-M12KS04-M1-B2 is listed under PNP proximity sensors from Omron industrial sensing products.

The Omron E2A-M12KS04-M1-B2 Proximity Sensor 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 NC 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 indicator is provided, while output reverse-polarity protection, power-source reverse-polarity protection, surge suppression, and short-circuit protection are specified.
Operating conditions for the E2A-M12KS04-M1-B2 cover -40 to 70°C, with storage from -40 to 85°C and humidity from 35% to 95%. Temperature influence is ±10% max. of sensing distance at 23°C from -25 to 70°C and ±15% max. from -40 to 70°C. Insulation resistance is 50 MΩ min. at 500 VDC, dielectric strength is 1,000 VAC for 1 minute, and voltage influence is ±1% max. within rated voltage ±15%. Brass is listed for the body and IP67 for protection. For another PNP E2A sensor with the same 4 mm sensing distance but NO operation and an M8 body, see E2A-M08KN04-M1-B1.
