1) What voltages are available?
Although 24VDC is the most frequently requested we do manufacture a full range of DC voltage and AC is possible using a silicon bridge rectifier.
2) Can the solenoid push, or pull?
The majority of types feature either a push version or a pull version. For some a push/pull type is available.
3) Is it available with a return spring?
All rotary solenoids are available with a return spring. The HL series linear solenoids also can be obtained with an internal return spring.
4) What effects do differing duty cycles have?
100% allows the coil to be continuously energised. Below 100% restricts the time a coil can be energised but it does increase the force output.
