Omron E2B-M12KS02-M1-B1: Inductive proximity sensor, M12, flush, Sn 2 mm, PNP NO output, M12 connector, 4-pin.
Status: In production
Brand: Omron
Product: Inductive proximity sensor, M12, flush
Rated sensing distance (Sn): 2 mm
Output: PNP, NO
Connection: M12 connector, 4-pin
Power supply voltage: 10 to 30 V DC
Degree of protection: IP67
The Omron E2B-M12KS02-M1-B1 is an E2B-series inductive proximity sensor with an M12 short housing in nickel-plated brass and a PBT sensing face, built for flush (shielded) mounting. The rated sensing distance (Sn) is 2 mm ±10% and the setting distance 0 to 1.6 mm. Omron recommends shielded models for better noise immunity. The standard sensing object is a mild steel (ST37) plate of 12 × 12 × 1 mm; the average response frequency is 1,500 Hz and the differential travel at most 10% of the sensing distance.
Supply voltage is 10 to 30 V DC (including 10% peak-to-peak ripple) and current consumption 10 mA max. The PNP open-collector NO output switches up to 200 mA with a residual voltage of 2 V max. Reverse polarity, surge and short-circuit protection are built in. The sensor connects via a 4-pin M12 connector and has 4 yellow LEDs at 90° intervals. It is rated IP67 and operates from −25 to 70 °C. Overall length is 51 mm, thread length 31 mm and tightening torque 12 N·m.
