DRIVE
• Low friction screw drive (linear actuator) rated for -5 ºF to +160 ºF (-21 ºC to +71 ºC).
• Powered by a 12 V motor with integral case hardened steel gear reducer. Motor speed reduced to 260 rpm.
Generates 520 inch lb. of torque at 12 V.
• Maximum opening arc of 110º. Approximate opening time (90º): 18 seconds, depending on weight of gate.
POWER
• The system is powered by a 12 Vdc automotive or marine battery.
• Battery charge is maintained by a 120 Vac, 18 Vac output transformer [rectified to 14.5 Vdc (40 VA) through
the GTO control board] or by optional GTO Solar Panels [the panel should generate minimum of 10 W at
600 mA]. 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.
• One (1) blade-style control board fuse is rated for 15 A.
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
• GTO microprocessor-based control board is set for dual leaf, pull-to-open gate installations. DIP switches can
be adjusted to accommodate an optional kit for push-to-open gates (see Accessory Catalog).
• Control board has temperature compensated circuits.
• A circuit on the control board regulates charging. "Sleep draw" is 25 mA; "active draw" is 2 to 5 A.
• Auto-memorization of digital transmitter code.
• GTO remote-mounted RF receiver tuned to 318 MHz.
• Opener length with push-pull tube fully retracted is 37 1 /
4 ", mounting point to mounting point. Max stroke 19".
• Adjustable auto-close timer (OFF to 120 s), and obstruction sensitivity.
• Power terminal bock accommodates a transformer or solar panels.
• DIP switches simplify setup of gate opener.
• Accessory terminal block fully compatible with all Mighty Mule access controls.
• Control board allows connection of safety edge sensors and photoelectric sensors.
• Audio entrapment alarm sounds if unit encounters an obstruction twice while opening or closing.
OPERATIONAL CAPACITY
• The Gate Capacity Chart shows approximate cycles, per day, you can expect from the Mighty Mule 352 Au-
tomatic Gate Opener when powered with a transformer. Actual cycles may vary slightly depending upon the
type and condition of gate and installation.

NOTE: BALL BEARING HINGES SHOULD BE USED ON ALL GATES WEIGHING OVER 250 LB.
To determine the number of cycles the gate opener will perform using solar panels, please see the specifications
listed on page 22 or call (800) 543-1236 or (850) 575-4144 for more information.
* An operation cycle is one full opening and closing of the gate.
NOTE: "NR" indicates
