About Continuous (CO.) SW82-4 Solenoids
Continuous contactors, by design, are predominantly for drive functions on vehicles; they switch slower than intermittent solenoids and are recommended for prolonged contact periods.
The contactors are compact and fully serviceable, with a full range of spare parts available. The SW82 has M8 stud main terminals and 6.3mm spade coil connections. It can be mounted via M4 tapped holes or by purchasing mounting brackets. Mounting can be horizontal or vertical. When vertical, the M8 contact studs should point upwards.
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). |
