Pullkey Switch
By Austdac Pty Ltd
Catalog ID:
PKEY001
The Austdac pullkey or cable-pull limit switch type ESS3 finds many applications in controlling distributed plant such as conveyors or belts used in the mining or materials handling industries. The pull key is used to provide controlled stop functions for distributed plant or conveyors. The pull key can be operated using the front centrally located knob or each of the two side located flexible cable-pull actuators. The side cable-pull actuators can be used in tensioned and non-tensioned systems.Each of the cable-pull actuators is fitted with an eyelet to allow easy attachment of the lanyard or pull wire using some of the accessories described in section 7 of this manual. The ESS3 provides six independent uncommitted voltage free changeover or SPDT contacts for use in controlling the conveyor. The contacts can be configured to handle low voltage mains circuits up to five amps or extra low voltage circuits with currents as low as 100uA. The pull cord operated pull key measures 270mm (W) x 100mm (H) x 115mm (D) including its convenient mounting feet that allow the ESS3 to be mounted on a gear tray or conveyor structure with two M10 (3/8”) bolts. The large centrally located knob provides indication of the switch status through its position and through two reflective ‘cats eyes’ that can only be seen from a long distance when the switch is in the stop or lockout position.
