WKA-AX - Limit switch

You will stop the monorail exactly where you need to, or find out where it is at a given moment—one sensor, two operating modes.

WKA-AX, czujnik krańcowy do sterowania napędami kolejek podziemnych w strefach zagrożonych wybuchem metanu

// DESCRIPTION

What it is

The WKA‑AX limit switch operates in the ATUT‑NET intrinsically safe network and controls transport system drives in rooms at risk of methane and coal dust explosions.

You choose one of two operating modes. The WKA‑AX/B version switches off and interlocks the monorail drive when the train runs over the switch protecting the route, for example, at the beginning or end of the route. The WKA‑AX/S version informs the control system about the train's position on the route, for example, to correct the distance travelled.

You can order each version with a WAT/M22 cable gland, designation /W, or a ZAT/4/G cable connector, designation /Z, depending on the installation.
