Brake Option (E, F, G, H)
A brake option is available on the ER Series size 50 and 80
rodless actuators to prevent back driving of the bearing
carriage when power is removed from the motor. The brake
is a spring loaded, friction disc type that requires a separate
power signal (24 VDC or 115 VAC) to the solenoid that
releases the brake. The brake option attaches directly to the
rear of the ball or Acme screw, preventing movement of the
bearing carriage for static conditions. Options which mount
to the rear of the actuator are not available with the brake
option.
Ordering Information
Specify brake option, voltage, and connector style within
complete actuator part number.
E: 115 VAC with flying leads and cable gland
F: 24 VDC with flying leads and cable gland
G: 115 VAC with Brad Harrison and 4 m cable
H: 24 VDC with Brad Harrison and 4 m cable
Notes:
• Brake option available on ET/ER50, ET/ER80, and ET/ER100.
• To be used as static brake only! Not intended for
dynamic braking.
• Contact factory for use with inline or reverse parallel
motor styles.
