The external diagram in the catalogue shows the energized ON position. The plunger is in contact with the body and has a stroke of 0. The return spring equipped push solenoid shows both the ON position, the magnetically held retracted position, and the return OFF position.

The life expectancy varies depending on how it is put to use. Loads perpendicular to the plunger action especially shorten a solenoid’s life. It also depends on things such as the surface treatment applied to the plunger, so please send us life expectancy inquiries including the type of solenoid and usage specs, i.e. voltage, load, mounting direction and so on.

Because solenoids are electromagnets, the further away from the coil the weaker the magnetic force and therefore the less stable the plunger is. The range displayed in the graph is the range of stable plunger retraction when horizontal. The operating range goes beyond this but the longer the stroke the less correctly the pull force operates.

Yes, we can recommend solenoids based on your needs. We recommend solenoids based only on the information we receive from the customer, however, so the final decision ultimately must be made by the customer.

Unfortunately we have no water-resistant or waterproof products. Please take care to avoid exposing solenoids to water or excess heat during use OR storage, as solenoids are electronic components.

We can build custom solenoids whether based on a small change in specs or on large changes in specs that require custom die machining. We purchase and manufacture in lots so please inform us of the expected order size when sending specs.

Our minimum order size is 1 unit.

The date of shipment for products in our catalogue may vary based on order size but we generally ship small orders on the same business day. Please see the Products page for detailed shipping information for individual products.

Springs, screws and other fittings are necessary to mount solenoids but unfortunately we do not sell these items.
