Inductive proximity sensor · 8 mm barrel 3 mm sensing range PNP NO M12 connection · Eaton E57-08GE03-GDB
What this product is for
This inductive proximity sensor is used for non-contact detection of metal targets in industrial automation, machine building, and material handling equipment. It is suited to installations where a compact 8 mm threaded barrel sensor is needed.
Use for
- Detecting metal machine parts, brackets, and actuators
- Position sensing on automated equipment
- Compact sensor mounting in tight spaces
- PLC and control panel inputs using a PNP normally open signal
Avoid for
- Applications requiring detection of non-metallic targets
- Safety-rated sensing functions
- Installations that need a longer sensing distance than 3 mm
Best for
Best for OEMs, maintenance electricians, and automation contractors who need a compact M8 cylindrical inductive sensor with M12 quick connection and DC PNP output.
Installed in
Commonly installed in packaging machines, conveyors, assembly equipment, fixtures, and automated production cells. The 8 mm diameter body is approximately 0.31 in, and overall length is approximately 2.79 in (71 mm).
Why this product exists
This sensor provides reliable metal target detection where mechanical limit switches would wear or where space is limited. The M12 4-pin connection helps simplify replacement and field wiring in machine environments.
Compared with similar products
Compared with larger barrel sensors, this 8 mm model fits tighter mounting locations but offers a shorter 3 mm sensing range. As typical guidance, smaller inductive sensors are commonly chosen where mounting space matters more than extended sensing distance. Actual performance depends on target material, mounting, and installation conditions.
