The moving coil and termination is simply plugged in via any length of tail. This makes the device neater and because the flex is terminated directly onto the coil, less stress is created at the joint making it resistant to damage or disconnection through constant movement and material stress.
This connection method makes the motors perfectly suited for use in pick and place machines and pressure or position sensitive control valves. Similarly, the cover reduces noise and prevents ingression by airborne contaminants.
