Open Frame Solenoids

Like other linear solenoids, open frame solenoids are on/off type actuators that develop force in one direction when energized. The return force must be provided externally, e.g. by a return spring.

They are used in many versions in a myriad of applications; this can cause issues with some manufacturers regarding quantities, delivery time, quality and, last but not least, price. That’s why Geeplus works directly with three distinct production lines, all in different locations and with differing manufacturing equipment. 

Standard open frame solenoids are pull type solenoids, but push type versions can be custom made. We also offer latching solenoids, where one position is held by a permanent magnet with no electrical power applied.

NOTE: Because each application is different, requiring varying levels of resistance, a spring is not included with these parts. Our engineers recommend a simple spring kit to choose the correct spring for each application. We can include them in volume if we have the specifications.

Basic Characteristics of Open Frame Solenoids:

• Holding force up to 30N (in end position, energized)
• Stroke up to 15mm (depending on type)
• Life expectancy up to 5 million cycles
• Miniature versions available: standard versions from 8 x 10 x 15mm
• Many mechanical options
• Rapid delivery service for RD series (4 weeks)
