Proximity switches
series KT-21 and KT-50 |
|
KT-xxP series of electronic (PNP) proximity switches eliminates negative features of reed relays. Those switches are fully electronic, which brings excellent properties, long lifetime and integrated protections. We also offer reed switches, series KT-xxR. Series KT switches can be used with all types of Stránský a Petržík‘s cylinders. For various types of cylinders the right bracket must be used. Switches KT-50 can be used with cylinders with T-slot made by other producer. |
