Omron E2A-M12LS04-M1-B3 Proximity Sensor
Omron E2A-M12LS04-M1-B3 is an M12 shielded inductive proximity sensor with a 4 mm sensing distance, 0 to 3.2 mm setting distance, and long-body construction. It provides a DC 3-wire PNP output with combined NO and NC switching through an M12 connector and operates from 12 to 24 VDC. Response frequency is 1,000 Hz, while control output is rated 200 mA max. at 32 VDC max. with a 2 V max. voltage drop. Output reverse-polarity, power-source reverse-polarity, surge, and short-circuit protection are specified. The E2A-M12LS04-M1-B3 is part of M12 shielded proximity sensors from Omron automation sensing products for industrial positioning and metal detection.

The Omron E2A-M12LS04-M1-B3 Proximity Sensor uses a cylindrical M12 shielded inductive sensing body with a 4 mm sensing distance, 0 to 3.2 mm setting distance, and long-body construction. It provides a DC 3-wire PNP output with both NO and NC switching through an M12 connector and operates from 12 to 24 VDC. Response frequency is 1,000 Hz, while control output is rated 200 mA max. at 32 VDC max. with a 2 V max. voltage drop. A yellow LED indicates operation. Output reverse-polarity protection, power-source reverse-polarity protection, surge suppression, and short-circuit protection are specified for the electrical circuit.
Operating conditions for the E2A-M12LS04-M1-B3 cover -40 to 70°C, with storage from -40 to 85°C. Environmental protection includes IP67 according to IEC 60529, IP69K according to DIN 40050, and EMC according to EN60947-5-2. The shielded sensing format supports installation close to surrounding metal, while the long body provides additional threaded length for adjustment through machine brackets. The combined NO and NC output offers two switching states from one sensor configuration. Brass-nickel-plated or stainless-steel housing options and PBT components are listed for the E2A construction. For an M18 E2A model with PNP NC switching and a longer 16 mm sensing distance, see E2A-M18KN16-WP-B2 2M.
