The TCI® solenoid motor is only 1.025" long, the most compact, space-saving solenoid available. The conical face design is able to handle higher forces than standard flat-faced solenoids with .180" to .200" strokes. The high-efficiency, precision wound coil maximizes the amount of copper in the allowable space for maximum force, and the two-wire set-up ensures a good quality ground can be established.
