Heat Sink
|
In order to reduce coil heating and to enable a larger ampere turn to be employed, a heat sink should be attached to a solenoid. Coil data of rotary solenoids, push-pull solenoids and tubular solenoids are measured and tested with a standard heat sink attached. Without a heat sink, a lower voltage than specified on the coil data charts, or lower duty cycle, must be used to avoid thermal damage to the coil. The coil data of small push-pull solenoids, self-holding solenoids and open frame solenoids, is shown without use of a heat sink. |
