Conveyor Safe-T-Pull Switches (South Africa)
Tripping occurs under the following conditions:–
(a) The trip wire is removed
(b) The trip wire is over tensioned
(c) The trip wire is activated
(d) Manual trip via reset knob.
The switch cannot be reset unless the trip wire is attached and correctly tensioned, Manual reset via the external reset knob is required after a trip has occurred.
Tamper Proof Switch Plate Mechanism.
Absolute simplicity in initial setup and adjustment.
Robust non-metallic enclosure.
Simple design ensures low maintenance.
Stainless steel internal compression type springs.
Pull rods 316 stainless steel.
Pull rods have spring loaded external dust protecting boots so the pull rod is always covered for extra seal protection.
Double lip oil seals on pull rods and reset operator for secure dust and weather protection to IP 67.
Non-metallic pull rod bushings.
Positive drive action switching contacts provides mechanical forcing of the trip contacts.
Complies to AS/NZS 3947.5.5: 2000 IEC 60947-5.5: 1997
Three fail safe trip mechanism to ensure safety.
Internal switch connections are fully shrouded for added safety during inspection.
Switches have forced open double break, double make Gold Flashed/Silver contacts for reliable low voltage signaling.
Cam design compensates for pull wire expansion/contraction up to 30mm either side of the set point.
Eliminates nuisance tripping due to vibration.
Pull forces to actuate trip @ 60Nm (6Kg) 90° to pull wire axis and 90Nm (9Kg) along pull wire axis.
Padlock facility provided as standard.
