About Intermittent (Int.) SU280 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 contactors have double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity. They are easy to install, with M5 tapped holes in the switch frame together with a range of available mounting brackets. Mounting can be vertical or horizontal, when vertical the M10 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). |
