Turck Bi1-EG05-AN6X-V1331 M5×0.5 inductive sensor NPN

Threaded barrel inductive sensor

The Turck Bi1-EG05-AN6X-V1331 is an M5 × 0.5 inductive proximity switch designed for flush mounting in metal structures. Its NPN normally-open output suits DC control circuits that require a sinking signal. The 1 mm rated switching distance targets precise presence detection in tight machine cavities. Automation engineers and maintenance technicians specify this sensor for compact positioning tasks.

Stainless steel housing under continuous operation

The 1.4427 SO stainless barrel resists coolant, cutting oil and cleaning agents encountered in machining cells. Rated for 10 to 30 VDC supply, the three-wire amplifier maintains stable switching behaviour across temperature cycles without derating. The sealed construction prevents ingress during high-pressure wash-down, so signal integrity persists shift after shift. No moving parts mean mechanical wear does not degrade repeatability over time.

M8 connector and flush mount practicality

The M8 × 1 male connector enables quick cable exchange without rewiring the sensor body. Flush mounting lets the sensor face sit level with surrounding metal, protecting the active face from impact by passing workpieces or tool changers. At 10 g the unit adds negligible mass to moving brackets or end-of-arm tooling. Buyers needing a larger sensing range or a PNP output must select a different model.
