Why Choose the IMO AB1/CN-1A Inductive Proximity Switch?
The IMO AB1/CN-1A is an ultra-compact M4 shielded inductive proximity switch designed for reliable non-contact detection of metallic targets in industrial machinery and automation systems. Featuring an NPN normally closed (NC) output, a 0.6 mm nominal sensing distance and an integral 2 m PUR cable, it provides precise sensing where installation space is extremely limited.
As part of the miniature AB inductive sensor range, the AB1/CN-1A combines a threaded M4 × 0.5 stainless steel housing with a shielded sensing configuration for flush installation. Its robust AISI 303 stainless steel body and PBT active sensing head make it well suited to repetitive position and presence detection in industrial equipment.
Operating from a 10–30 V DC supply, the AB1/CN-1A supports load currents up to 100 mA and switching frequencies up to 3 kHz. Integrated short-circuit and reverse-polarity protection, a yellow output-state LED and an IP67 protection rating help provide dependable performance in demanding machine environments.

Precise Non-Contact Detection for Industrial Automation
Inductive proximity switches detect metallic objects without mechanical contact, allowing machine control systems to monitor component presence and position while avoiding the wear associated with mechanically actuated switches. The AB1/CN-1A's miniature M4 construction makes this sensing principle available in particularly confined machinery and automation installations.
The shielded sensor can be installed flush within suitable metal surroundings while its NPN normally closed output provides a defined switching configuration for compatible control inputs. Fast switching, integrated electrical protection and robust stainless steel construction make the AB1/CN-1A suitable for repetitive industrial sensing duties.
