Proximity switches

series RZT7 and MZT8

These proximity switches are produced as reed switches or electronic switches. Advantage of these switches is that they can be used with all types of Stránský a Petržík‘s cylinders. It means, that there can be used not only several diametrs but also more types of cylinders (VDMA, compact, DIN ISO, etc.) in pneumatic circuit and for all cylinders only one type of switch can be used (it is necessary to select proper bracket for various types of cylinder - see table bellow). It brings cost savings at designing electrical cirquits, at connection as well as at cirquit maintaining.
Switch can be used with cylinders with T-slot made by other producers.

How to fix shitch on cylinder

1) We recommend to use bracket for tube with cylinder with guide unit, to provide sensing in section, where the guide unit is mounted.
The guide body inhibits using of bracket for tie rod / profile. On the other side, or in the area out of guide body, bracket for
tie rod / profile can be used.
Pneumatic cylinder type	Switch can be used
	directly	with bracket	with bracket for dovetail groove	With bracket for tube
	directly	with bracket	with bracket for dovetail groove	up to Ø25	up to Ø63	up to Ø125
