Special devices

The special devices from DOLD include emergency stop monitors as well as buttons and magnetically coded safety switches.

Special devices from DOLD include emergency stop monitors for the fast localisation of actuated emergency stop buttons, emergency stop devices and magnetically coded safety switches. The DOLD emergency stop monitors help to quickly and easily located actuated emergency stop buttons. This can significantly reduce the standstill times of machines and systems. Emergency stop devices from DOLD deactivate machines and/or place them in standstill. This thus reduces dangers to persons or damage to machinery as well as the manufactured products. With the coded magnetic switches from DOLD, the position of movable, rotatable or removable safety doors is monitored. The contactless devices can also be used for doors that are difficult to move or that are imprecisely positioned.
