Inductive Proximity Sensor A0C 8 mm barrel, 1 mm range, NPN NO, shielded, M12 connector A0C Eaton E57-08GS01-CDB

What this product is for

This inductive proximity sensor is used to detect metallic targets without physical contact in automated equipment, fixtures, and machine assemblies. The 8 mm threaded barrel suits compact mounting locations where a short sensing distance is acceptable.

Use for

Use for presence detection of metal parts, position sensing on automated machinery, indexing systems, and OEM equipment. It is commonly used where an NPN normally open output is required and where an M12 quick-disconnect sensor connection helps simplify replacement.

Avoid for

Avoid using this sensor for non-metallic target detection, safety-rated functions, or applications needing a longer sensing distance than 1 mm. Confirm controller input compatibility before ordering, since this model uses an NPN NO output.

Best for

Best for compact industrial sensing points, automated manufacturing equipment, and machine builds that need a shielded flush-mount style sensor body. It is a practical choice when space is limited and repeatable short-range metal detection is needed.

Installed in

Typically installed in machine frames, brackets, tooling stations, conveyors, and automated assembly equipment. The 8 mm diameter body is approximately 0.31 in, and listed product length is about 69-71 mm (approximately 2.7-2.8 in), depending on source listing format.

Why this product exists

This sensor provides reliable non-contact metal detection in a small cylindrical format with standard 10-30 VDC operation. The M12 4-pin connector supports faster service replacement than hard-wired cable styles in many panel and machine applications.

Compared with similar products

Compared with larger inductive sensors, this 8 mm model fits tighter mounting spaces but offers a shorter 1 mm sensing distance. Compared with cable-exit versions, the M12 connector version can be easier to service. As typical guidance, shielded flush-mount sensors are commonly selected where the sensor must sit close to surrounding metal; actual sensing performance depends on target size, material, mounting, and installation conditions.
