Open Frame Solenoids

Our range of Open Frame solenoids are a cost effective solution for high volume applications.

In terms of volume, the open frame solenoid is probably the most commonly used type. It has the advantage of many sizes and shapes being available, with plunger diameters from 3mm to 16mm and strokes from 1mm to in excess of 30mm. It is therefore chosen as a low cost effective solution for many applications. There are however, application circumstances which would deem open frame unsuitable. For example, demanding operation or harsh environments, such as secure parcel collection points.

Manufactured by our partners in the Far East, economics and logistics suggest that a minimum annual volume requirement of 3,000 pieces makes this option appropriate. For applications requiring lower quantities, please consider our Tubular and Low Profile linear products.
