In Pull type solenoids, the standard test conditions: is available in three plunger is pulled into the ambient temperature Ledex tubular solenoids diameters and five solenoid coil when the of 20C, 65% relative are rated for various sizes. Both push and coil is energized. In Push humidity. duty cycles ranging from pull types are available. type solenoids, the same is continuous to 10% duty. Additionally, each size true, however, the plunger and type is available with Starting Force has a shaft extension Note that maximum ON a choice of two plunger When determining which then pushes out time for a particular configurations: flat face an applications force through a hole in the application can be a factor and 60, as well as with or requirement, apply a 1.5 end of the solenoid case. which overrides the duty without an anti-rotation safety factor. For example: Please note, however, that cycle rating. For example, flat on the mounting a load requiring 4.5 lb the magnetic field cannot at 25% duty cycle, the bushing.
