Why Choose the IMO AB1/CP-1A M4 Inductive Proximity Switch?
The IMO AB1/CP-1A is a miniature M4 shielded inductive proximity switch designed for precise non-contact detection of metallic objects in compact industrial automation equipment. Its small threaded cylindrical body makes it particularly suitable for machinery where installation space is restricted and dependable position or presence sensing is required.
The AB1/CP-1A provides a nominal sensing distance of 0.6 mm and features a PNP normally closed (NC) output. Operating from a 10 to 30 V DC supply, the sensor supports load currents up to 100 mA and a switching frequency of up to 3 kHz, making it suitable for rapid detection in automated machinery.
Designed for demanding industrial use, the sensor combines an AISI 303 stainless steel M4 × 0.5 housing with IP67 environmental protection and a PBT active sensing face. A yellow LED provides clear output-state indication, while the integral 2 m PUR cable provides a durable pre-wired connection for machine installation.

The IMO AB1/CP-1A uses an electromagnetic field at its active sensing face to detect nearby metallic objects without physical contact. When a suitable metal target enters the sensing zone, the sensor changes the state of its PNP normally closed output, providing a dependable signal to a compatible PLC, controller or machine input circuit.
Its compact M4 × 0.5 housing, shielded installation design and 0.6 mm nominal sensing distance make the AB1/CP-1A particularly useful for precise detection of small machine components. With a 3 kHz switching frequency, IP67 protection and comprehensive electrical protection functions, it provides a robust sensing solution for high-cycle industrial automation.
