Omron E2B-M30KN20-M1-B2 Proximity Sensor
Omron E2B-M30KN20-M1-B2 is an M30 unshielded inductive proximity sensor with a 20 mm sensing distance, 0 to 16 mm setting distance, and short-body construction. It provides a DC 3-wire PNP output with NC operation through an M12 connector and operates from a 10 to 30 VDC power supply. Ferrous metal is the specified detection target, with a 60 × 60 × 1 mm standard sensing object. Response frequency is 100 Hz, and the control output is rated 200 mA max. at 30 VDC max. with a 2 V max. voltage drop. The E2B-M30KN20-M1-B2 is part of the M30 unshielded proximity sensor family from Omron sensing and control products.

The Omron E2B-M30KN20-M1-B2 Proximity Sensor uses an M30 cylindrical unshielded inductive sensing body with a 20 mm sensing distance, 0 to 16 mm setting distance, and short-body construction. It provides a DC 3-wire PNP output with NC operation through an M12 connector and runs from a 10 to 30 VDC supply. Ferrous metal is the specified detectable object, paired with a 60 × 60 × 1 mm standard sensing target. Response frequency is 100 Hz. The control output is rated 200 mA max. at 30 VDC max. with a 2 V max. voltage drop. A yellow operation LED is provided, together with reverse-polarity, surge, and short-circuit protection.
Operating and storage conditions for the E2B-M30KN20-M1-B2 cover -25 to 70°C, with IP67 protection according to IEC 60529 and EMC according to EN60947-5-2. Its M30 unshielded design provides the stated 20 mm detection distance while the short body helps reduce rear mounting depth. PNP NC operation provides a sourcing normally closed signal, and the M12 connector simplifies cable removal during maintenance. This combination is suited to applications requiring a larger sensing distance for ferrous-metal targets. For an M18 connector model with 16 mm sensing distance and NPN NO switching, see E2B-M18LN16-M1-C1.
