Omron E2A-M12LS04-M1-B1 Proximity Sensor
Omron E2A-M12LS04-M1-B1 pairs an M12 cylindrical long body with shielded inductive sensing for a 4 mm detection distance and 0 to 3.2 mm setting range. It provides DC 3-wire PNP NO switching through a 4-pin M12 connector and operates from 12 to 24 VDC. Response frequency is 1,000 Hz, with control output rated 200 mA max. at 32 VDC max. and a 2 V max. voltage drop. A yellow LED indicates operation, while reverse-polarity, surge, and short-circuit protection are specified. The E2A-M12LS04-M1-B1 belongs to the shielded proximity sensor range available from Omron automation products.

The Omron E2A-M12LS04-M1-B1 Proximity Sensor uses an M12 cylindrical long body with shielded inductive sensing, a 4 mm detection distance, and a 0 to 3.2 mm setting range. It provides DC 3-wire PNP output with NO operation through a 4-pin M12 connector and operates from 12 to 24 VDC. Response frequency is 1,000 Hz. Control output is rated 200 mA max. at 32 VDC max. with a 2 V max. voltage drop. A yellow operation indicator is provided together with output reverse-polarity, power-source reverse-polarity, surge, and short-circuit protection. These characteristics suit Omron M12 shielded proximity sensor applications requiring PNP NO switching.
Operating conditions for the E2A-M12LS04-M1-B1 cover -40 to 70°C, while storage extends from -40 to 85°C. IP67 according to IEC 60529, IP69K according to DIN 40050, and EMC according to EN60947-5-2 are specified. Brass-nickel-plated or stainless-steel housing options and PBT components are included in the construction information. Shielded sensing supports mounting close to surrounding metal, while the long threaded body provides additional positioning adjustment. Its M12 connector enables detachable cabling during maintenance. The 4 mm range and connector arrangement also fit Omron M12 PNP proximity sensor requirements. For a short-body M12 E2A alternative with the same sensing distance and a pre-wired 2 m cable, see E2A-M12KS04-WP-B1 2M.
