Why Choose the IMO AB1/AN-3A Inductive Proximity Sensor?
The IMO AB1/AN-3A is a miniature M4 inductive proximity sensor designed for precise, non-contact detection of metallic objects in industrial machinery and automation systems. As part of the IMO AB1 miniature cylindrical inductive sensor series, its compact threaded stainless-steel housing provides an effective sensing solution where installation space is limited.
This sensor features an NPN normally open (NO) output and a nominal sensing distance of 1 mm. Its shielded construction allows flush installation into surrounding metal, making it particularly suitable for precision positioning, component detection, machine sequencing and automated production equipment.
Operating from a 10–30 V DC supply, the AB1/AN-3A supports load currents up to 100 mA and a fast switching frequency of 3.5 kHz. A durable 2 m PUR cable, AISI 303 stainless-steel housing and IP67 protection rating provide dependable performance in demanding industrial environments.

Precise Non-Contact Detection for Industrial Automation
Inductive proximity sensors such as the IMO AB1/AN-3A detect metallic targets without requiring physical contact. When a suitable metal object enters the sensor's electromagnetic detection field, the sensor changes its output state, allowing a PLC or industrial controller to accurately determine the presence or position of the target without the mechanical wear associated with contact-based switching.
The AB1/AN-3A combines its miniature M4 threaded housing with a 1 mm nominal sensing distance and fast 3.5 kHz switching frequency. Its shielded construction, robust electrical protection and stainless-steel body make it particularly useful for compact automated machinery and precision mechanisms requiring dependable high-speed sensing.
Typical Applications
- Precision machine positioning and detection.
- Compact automated production machinery.
- Robotics and robotic gripper systems.
- Component presence and position monitoring.
- Electronic assembly equipment.
- Packaging and processing machinery.
- High-speed counting and detection systems.
