Description:
The ZQ900 is designed to provide continuous emergency stop control along exposed areas of machinery and conveyors which present hazards to operator/maintenance personnel. Unlike E-Stop pushbuttons, emergency cable-pull systems can be actuated at any point along the “trip wire”. The unit features a double-break contact block offering a choice of five contact variations which change state when the cable is pulled or goes slack. Thus the switch can be actuated if an operator falls into, is pulled into, or leans on the trip wire. In addition the unit features an optional integrated E-Stop pushbutton, a position indicator for easier installation, a button reset, three cable entries, and an optional signaling lamp. The unit is capable of spanning lengths of up to 50 meters. Its rugged, metal housing and watertight design (up to IP67) make it ideal in hostile environments. control along exposed areas of machinery and conveyors which present hazards to operator/maintenance personnel.
