Albright SW61-128 series 8VDC sealed miniature single-pole, double-throw (SPDT) solenoid contactor, intermittent.
- Albright SW61 series contactors have been designed for a compact DC contactor application. Typical applications include switching small traction motors, hydraulic power packs and small electric winch motors.
- These contactors have closed contact housings and are sealed to inhibit moisture ingress or other contamination.
- All contactor builds are to a very high standard and employ the 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.
- Special sealed build, as a "P" type with rubber gasket.
- 2070-776 bracket mounted on the left-hand side of coil terminals, negative side with bracket extensions pointing upwards.
- Very Intermittent coil, 10% duty cycle.
Dimensions
- Height, including terminals and coil base cap: 81.4mm.
- Coil width: 35.9mm.
- Cap width: 35.9mm.
- Depth: 32.8mm.
About Intermittent (Int.) SW61 Solenoids
Intermittent contactors, by design, are predominantly used for hydraulic functions on vehicles; they make and break quicker than continuous solenoids and are not 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, either supplied fitted or 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). |
