Application fit

The Turck BI25-G47SR-VN4X2 is a flush-mount inductive proximity sensor with a Pg36 threaded brass barrel. Its NPN changeover output and 10…65 VDC supply range suit industrial control panels and machine-level automation where a metal-target detector is required.

Upgrade path

The sensor replaces older limit switches or lower-range inductive units that lack a complementary contact or a terminal-chamber connection. The jump is worthwhile when wiring simplicity and a chrome-plated CuZn housing rated for harsh environments are specified.

Sustained operation

A 25 mm rated switching distance and metal housing maintain consistent detection through vibration, coolant exposure and temperature cycling. The terminal chamber and dual cable entries keep terminations secure during continuous duty cycles.

Questions about this item

What thread size does the G47 threaded barrel require for mounting?

The sensor uses a Pg36 threaded barrel for flush mounting in a metal housing.

How do the two cable entries connect during installation, and which wiring step is often missed?

The terminal chamber accepts axial or radial cable entry; the step often missed is wiring all four DC conductors for the complementary NPN changeover contact.

Which part of the sensor will need replacement after extended use in a 10…65 VDC application?

The chrome-plated brass housing and internal switching element are rated for long service; no user-replaceable wear parts are specified for this inductive sensor.
