The sensors sit in 316 stainless steel and have weld-field immunity for use in harsh- duty environments.

An integrated predamping protection function reduces the sensor’s metal-free mounting area, which lets traditionally flush-mounted sensors be recessed by half a turn for more mechanical protection. Nonflush-mounted sensors can be embedded in metal up to the outer edge of the thread on barrel-style sensors and on all four sides of rectangular-style sensors.

The sensors are available with extended 2-mm sensing ranges for flush-mount versions or 6-mm ranges for nonflush applications. All sensors are three-wire dc, 10 to 30 Vdc, with pnp normally open or closed, or npn normally open versions.
