Types of Limit Switch Units
In our own enclosures (optionally of polyamide, polycarbonate, polyester or aluminium) different sensors, according to customer's requirements, are installed. Standard possibilities are:
Intrinsically safe slot-type sensors
Intrinsically safe cylindrical sensors
Intrinsically safe printed circuit board (pcb-)sensors
Final position indication with microswitches
In addition to the standard versions we are able to offer special solutions, e. g. additional cable entries, power supply via plug-in connectors, triple sensors a. o.
|Technical data||BS 65*|
|Max. voltage||1000 Volt|
|Max. amperage||13 Ampere|
|Max. conductor cross-section||16 mm²|
The values are maximum values, the actual electrical values are determined by the components installed. Within these limit values the manufacturer determines the design values and, thus, ensures observance of the maximum surface temperature and the permitted operating temperature of the components.
In order to be able to establish an interface between the limit switch unit and the actuator mounting brackets according to VDI/VDE 3845 are required.
These mounting brackets, manufactured by BöSha - of superior high-grade steel - are fitted to the actuator by means of screws.
