The physical size of the solenoid is also a big factor in the force vs. stroke relationship. A larger solenoid is going to have a greater number of possible wire turns in the coil, enabling it to create much more force for the armature than a smaller solenoid. Pontiac Coil offers a wide selection of standard solenoid sizes as well as custom sizes that may be available upon request. Additionally, these parts are available in chassis or panel mount with either quick connects or flexible wire leads for termination. Custom options may also be available for mounting and terminations upon request.
