Electromechanical Safety Switches With Electrical Monitoring
From DOLD
Electromechanical safety switches monitor safety
guards, safety gates and other safeguarding equipment. Only
after successful input of the key the access can be opened.
Electromechanical safety switches are used in
different safety areas. Often they are used in safety applications
in which the safe protection and monitoring of movable separating
protection devices must be ensured.
The locking unit can only be opened and unlocked after insertion
of the key. When opening the access (safety guards, safety
gates etc.) hazardous machines or systems must immediately
be switched off and a restart must be prevented. Only when
the access has been closed and the locking been returned in
its starting position, the key can be removed again and the
interlock will be activated. Only in this condition the machine
can be switched on again.
RXK01M / RX10A
Mechanical
guard lock with actuator position monitoring
The actuator can be removed and the
contacts are switched after the key has been inserted
on top. The RX10A variant offers electric monitoring
of the key
RXK11M / RX11A
Mechanical
guard lock with key exchange and actuator position
monitoring
After the first key has been inserted above, the
second key and the actuator can be removed, thereby
operating the contacts; The RX11A variant offers electric
monitoring of the first key
RX10K01M
Mechanical
guard lock with monitoring of second key
After the first key has been inserted above, the
actuator and the second key can be removed, thereby
operating the contacts; depending on system coding,
this function can be inverted and the first key is
electrically monitored
RX11M
Key
exchange unit with monitoring
The second key can be removed after the first key
on top has been removed; this switches the contacts
