MIGHTY MULE 571W/572W GATE OPENER
Technical Specifications
NOTE: Ball bearing hinges should be used on all gates weighing over 250 lb.
The Gate Capacity Chart below shows the recommended maximum gate length to weight. The minimum
recommended gate length is 5 ft.

DRIVE
_____________________________________
• Low friction screw drive (linear actuator) rated for -5 °F to +160 °F (-20 °C to +71 °C).
• Powered by a 12 V motor with integral gear reducer. Motor speed reduced to 348 rpm at 12 V.
• Maximum opening arc of 110°. Approximate opening time (90°): 18 seconds, depending on weight of gate.
_____________________________________ POWER _____________________________________
• The system is powered by a 12 Vdc battery (included). A second Mighty Mule battery may be used (not included).
• Battery charger is on the control board and maintained by a 120Vac to 19VDC output transformer or by
optional Solar Panels; the panel should generate minimum of 10 Watts (600 mA/20 watt max.). A diode on the
control board prevents battery discharge.
IMPORTANT:
Never use
both
transformer and solar panel— this will
damage the battery and control board.
• Three (3) Mini blade-style fuses rated for 25A.
•
NOTE: The transformer should not be directly connected to any battery. Do not replace fuses with higher
ampere rated fuses; doing so will void your warranty and may damage your control board.
_____________________________________ CONTROL _____________________________________
• Microprocessor-based control board is set for single or dual leaf, pull-to-open or push-to-open installations.
• Control board has temperature compensated circuits.
• Learn based digital transmitter technology provides millions of codes for enhanced security.
• Receiver is tuned to 318 MHz
• Opener length with push-pull tube fully retracted is 40 1/4", mounting point to mounting point.
Maximum stroke is 20".
• Adjustable auto-close timer (OFF to 3–120 seconds), and Dual Sense Technology™ stall force.
• Power terminal block accommodates a transformer or solar panels.
• Accessory terminal block fully compatible with all Mighty Mule access controls.
• Control board allows connection of edge sensors and photoelectric sensors.
• Audio entrapment alarm sounds if unit encounters an obstruction twice while opening or closing.
