Threaded-barrel inductive sensor

The Turck NI40-G47SR-VN4X2 is a 15750 inductive proximity sensor with an NPN complementary contact output. It has a threaded barrel construction sized G47 and a chrome-plated brass housing. The sensor operates on 10 to 65 VDC and provides a rated switching distance of 40. It mounts non-flush and connects through a terminal chamber with two cable entries.

Industrial maintenance and automation engineers

This sensor suits engineers who need a metal-housed inductive switch for non-flush mounting on machinery or conveyors. The DC 4-wire design fits control circuits that require a complementary NPN output. Buyers who need a flush-mountable sensor or a PNP output type should look at alternative models.

40 rated switching distance

The single specification that decides fit is the rated switching distance of 40. This figure determines whether the sensor will reliably detect the target at the required gap in your application. Verify this distance against your mechanical layout before ordering.

Questions about this item

Will the Pg36 threaded barrel or the chrome-plated brass housing need routine replacement under normal operation?

The sensor uses a solid chrome-plated brass barrel with Pg36 threading and has no moving parts, so no scheduled replacement of the housing or threads is required.

What is the maximum operating voltage before the NPN complementary output stage reaches its limit?

The DC supply range is 10 to 65 VDC; exceeding 65 VDC will push the output stage beyond its rated limit.

How much heat does the 282 g brass housing dissipate when the sensor runs continuously at 65 VDC?

The metal housing acts as a heat sink for the internal electronics; at the rated 10…65 VDC supply the unit stays within its thermal design without external cooling.
