About Continuous (CO.) SW85 Solenoids
Continuous contactors by design are predominantly used for drive functions on vehicles, they make and break slower than intermittent solenoids and are 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). |
