SW61-14 series 80V miniature single pole double throw solenoid contactor.
- The SW61 is a miniature series single pole, free standing, compact contactor. It is designed to fill the gap between 30 ampere relays and 100 ampere contactors.
- Devised for both interrupted and uninterrupted loads, the SW61 is suitable for switching Resistive, Capacitive and Inductive loads. Typical applications include switching small traction motors, hydraulic power packs and small electric winch motors.
- All contactor builds are to a very high standard and employ best quality materials: phenolic contact housings, Silver-alloy contacts and class H (180℃) winding wire for the coils.
- Repair kit: not available on this unit.
Dimensions
- Height including terminals and coil base cap: 81.0mm.
- Coil width: 37.0mm.
- Depth including fixed contact bar: 47.0mm.
About Continuous (CO.) SW61 Solenoids
Continuous contactors by design are predominantly for drive functions on vehicles; they make and break slower than intermittent solenoids, and are recommended for prolonged contact periods.
The SW61 features single pole, double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity. The SW61 has M6 stud main terminals and 6.3mm spade coil connections. It can be mounted via M4 tapped holes or mounting brackets, supplied as separate items. Mounting can be on the side or base of the contactor.
Interrupted Current: The opening and closing on load with frequent switching (resulting in increased contact resistance). |
Uninterrupted Current: No or infrequent load switching requirements (maintains a lower contact resistance). |
