products / linear solenoids

Geeplus offers a great variety of solenoid actuators including rotary solenoids, linear solenoids, open frame type solenoids both as simple on/off type actuators, as latching solenoids and bistable solenoids.

Our solenoids are „high performance“-products designed for industrial applications although in principle they are simple.

In case you cannot find the right product for your application within our standard products we are happy to adapt existing design with respect to electrical or mechanical properties or develop completely new products for you.

We differentiate the following main product groups for our solenoid actuators:

• Push-Pull Solenoids: robust linear on/off type actuators; optimised for high holding force
• Tubular Solenoids: robust linear on/off type actuators; optimised for long stroke
• Open Frame Solenoids: linear on/off type actuators in costeffective open frame version linear latching solenoids
• 3-Position Solenoids: linear on/off type actuators with 3 positions as costeffective open frame version or as tubular version
• Proportional Solenoids:controllable in force for very limited strokes

For all these actuators a so called Pick& Hold-circuit may be a good additional component. Pick& Hold circuits supply a higher peak current - and therefore force - for a limited time. In some applications this allows for a smaller actuator which might help to overcome size and weight constraints.
