Linear Actuator Swing Gate Operator for Residential and Light Commercial Installations The Maximum Controls MAX Ultra Arm is a heavy-duty 24V DC linear actuator swing gate operator designed for residential and light commercial applications. Made in the USA, the actuator uses a direct gear drive with a 2 in tubular stainless steel output shaft, built-in mechanical limit switches, and a powder coated aluminum housing. Stroke extends from a minimum of 39.1 in to a maximum of 60.3 in. Gate capacity scales with leaf length: 1,600 lbs at 8 ft, 1,200 lbs at 12 ft, 800 lbs at 16 ft, and 600 lbs at 18 ft. Both push-open and pull-open installation orientations are supported. The operator is UL 325/991 Class I, II, III, and IV compliant, meets the UL 2018 standard, and is ETL listed and CSA approved. The built-in two limit switch system uses adjustable mechanical limit switches and independent slow-down switches to control gate position and deceleration at both the open and close endpoints. DSP motor control with adaptive obstruction sensing and intelligent ramp-up and ramp-down governs gate movement, with two independently adjustable closing speed controls at 16 positions each, enabling asymmetric closing synchronization for bi-parting installations where gate leaves open to different angles. Mechanical and electrical gate release functions are built in, with key-activated manual release for power failure scenarios. Security features include a Tamper Alert relay that activates on forced gate movement, a Gate Disable function that blocks all standard open commands except Fire Department and Max Open inputs, advanced anti-tailgate detection, and magnetic lock relay outputs with selectable delay times. The operator is rated for continuous duty operation from -4°F to 165°F (-20°C to +74°C) without a heater, and lightning protection covers all 35 input, output, and communication channels at up to 20,000V and 10,000A. Key Features Made in USA; 24V DC direct gear drive with 2 in tubular stainless steel output shaft and powder coated aluminum housing. No internal chains, belts, or pulleys. Built-in two limit switch system with independently adjustable mechanical limit switches and slow-down switches for precise open and close positioning. Gate capacity scales to 18 ft leaf length: 1,600 lbs at 8 ft, 1,200 lbs at 12 ft, 800 lbs at 16 ft, and 600 lbs at 18 ft. Stroke range 39.1 in to 60.3 in. Two independently adjustable closing speed controls at 16 positions each, enabling asymmetric closing sync for bi-parting installations with unequal opening angles. Tamper Alert relay activates on forced gate movement; Gate Disable blocks all standard open commands from tampered keypads or exit loops, activatable by key-switch or timer. Continuous duty rated from -4°F to 165°F (-20°C to +74°C) without a heater. Lightning protection across all 35 channels rated up to 20,000V and 10,000A, guaranteed to withstand any strike beyond 50 ft. Optional Max Cloud App supports cellular remote operation, virtual transmitter management for over 10,000 users, time-restricted access, guest pass issuance, and remote diagnostics retrieval. Technical Specifications Model: MAX Ultra Arm Manufacturer: Maximum Controls LLC (Made in USA) Gate Type: Swing gate (linear actuator) Application: Residential / light commercial Motor: 24V DC Drive System: Direct gear drive; 2 in tubular stainless steel output shaft Housing: Powder coated aluminum Actuator Stroke: Min 39.1 in (993.5 mm) / Max 60.3 in +/- 0.39 in (1,531 mm +/- 10 mm) Nominal Thrust: 5,500 N Maximum Operating Current: 6A for max 10 seconds Gate Capacity: 1,600 lbs at 8 ft / 1,200 lbs at 12 ft / 800 lbs at 16 ft / 600 lbs at 18 ft Installation Options: Push open (outside property) or pull open (inside property) Limit System: Built-in two mechanical limit switches with adjustable slow-down switches Input Power: Switchable 115V AC or 230V AC Battery Backup: Two 12V 7Ah AGM batteries (via AC Control Box); approximately 500 cycles; three selectable modes Battery Warranty: 1 year Operating Temperature: -4°F to 165°F (-20°C to +74°C) Lightning Protection: Up to 20,000V / 10,000A; 35 channels Actuator Shipping Weight: 27 lbs AC Control Box Shipping Weight: 38 lbs (sold separately) Compliance: UL 325/991 Class I, II, III, IV; UL 2018; CSA; ETL listed Warranty: 2 years or 100,000 cycles, whichever comes first; 1 year on batteries Condition: New Conclusion The MAX Ultra Arm is sold as a standalone actuator. The MAX AC Control Box is required for operation and is available separately. For bi-parting installations, a second MAX Ultra Arm actuator and the MAX 40 ft. Cable are required for secondary communication. Adjust limit switch positions after installation and cycle the gate open and closed several times to confirm positioning before finalizing the limit and slow-down settings. The optional Max Cloud App is not compatible with the Phantom F6 or 2000 Plus models. Warranty coverage applies only to products purchased through authorized distributors.
