Quick Connect Option for Switches/Sensors
An optional connector is available for all styles of switches.
The male plug can be a snap-in or a threaded type connector.
The following table provides part numbers for a mating 5 m (16 ft)
polyurethane covered cable connector. The manufacturers are

Brake Option
The brake option (only available on ET Series size
50, 80, and 100) prevents back driving of the
cylinder rod when power is removed from the motor.
The spring loaded, friction disk-type brake requires
a separate power supply (24 VDC or 115 VAC)
provided to the solenoid. This power keeps the
brake disengaged allowing motion. When this
power is removed (when the unit is at rest or during
a power failure), the brake engages preventing
back-driving. The brake mounts directly to the rear
of the screw. For servo systems, the brake option is
only available in the parallel mounting configura-
tion. For stepper systems, the brake may also be
applied to the rear shaft of the motor. Refer to
ordering information (p. 7) for coding of options.
Consult factory for details concerning this option.
