About Intermittent (Int.) SU280 Solenoids

 Intermittent contactors by design are predominantly used for hydraulic functions on vehicles, they have a stronger coil which allows them to make and break quicker than continuous solenoids.

 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.

 Magnetic Latching: The contact position is secured with the use of a permanent magnet within the assembly. The coil requires a pulse to close the contacts and a reverse polarity pulse to operate the armature and open the contacts, but otherwise remains in the last energised state without the need for power. It should be noted, therefore, these are not failsafe.

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).
