SW85-50 single-acting Normally Closed (NC) 48V solenoid contactor for intermittent use.
- The SW85 series of SPST contactors has been designed for direct current loads, particularly motors as used on small electric vehicles such as light industrial trucks, powered invalid cars, etc., they have double-breaking contacts with Silver-alloy contact tips, which are weld resistant, hardwearing and have excellent conductivity.
- Contact replacement kit part number 2070-388 is available for this unit.
- Height including terminals and coil base cap: 90mm.
- Coil width: 40mm.
- Cap width: 50mm.
- Cap depth: 39mm.
About Intermittent (INT.) SW85 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 SW85 features single pole double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity. The SW85 has M8 stud main terminals and 6.3mm spade coil connections. Mounting is via M4 tapped holes for mounting brackets supplied as separate items. Mounting can be horizontal or vertical, when vertical the M8 contact studs should point downwards.
Please note: Normally Closed contacts are not suited to make and break load.
|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). |
