This ON time and OFF cycling can be repeated continuously over total life of the solenoid. As the ON time decreases and the OFF time increases, more current can be applied to the solenoid without causing coil overheating. An intermittent duty unit with extremely short ON time. This is maximum input power for that size solenoid. All coils for our standard solenoids are wound to order on demand.
Coils can be wound for any DC voltage.
For the very small size units operating at the higher voltage levels, special coils may be required. In operation, the coil resistance will increase due to the heating of the coil wire. The actual temperature of wire in the coil winding. It is the combination of ambient coil temperature plus heating due to current flow through the coil. The stable coil wire temperature with no electrical power to the solenoid.
