Magnetic AutoControl Barrier Arm Buyer's Guide
What Is a Barrier Arm?
A barrier arm is a motorized gate that rises and lowers to control vehicle access at entry or exit points. You can find these barriers in parking garages, surface lots, toll plazas, gated communities, government facilities, airports, and ports. Businesses utilize them to manage traffic flow, prevent unauthorized access, and enhance overall site security. Magnetic AutoControl is a leading name in the barrier arm industry, offering a comprehensive range of openers, arms, and accessories designed for commercial and high-traffic applications.
Choose the Right Opener for the Job
Every site has unique demands, and Magnetic AutoControl provides three distinct categories of openers to ensure you select the right equipment for your specific application. Understanding the differences between toll, parking, and access openers will save you time and money before you place an order.
Toll / High-Speed Openers
Built for highways, toll plazas, and high-volume lanes where cycle speed is the top priority. These units open in as little as 0.3 to 0.6 seconds and handle constant traffic without wearing down.

Designed for garages, surface lots, and commercial properties with steady daily traffic. The Parking Pro is rated at a 100% duty cycle with a 1.3-second open and close time.

The right fit for gated communities, private roads, ports, government buildings, and lower-traffic entry points. Select configurations support 24V solar power for off-grid installations.
Shop Access OpenersChoose Your Arm Type
Once you have the right opener selected, the arm type matters as much. The arm is what vehicles see, what takes the wear, and what determines how well your lane is secured. Magnetic AutoControl offers three main arm types to cover the full range of installations.
MicroBoom
A highly visible octagonal arm available in straight and articulated configurations from 10 to 20 feet. Works with skirts for added security, and the MicroBoom-AT soft foam version is built for toll applications.

Shop MIB / MBE ArmsKey Features to Consider
Beyond the opener model and arm type, a handful of features will determine how well your barrier arm performs day-to-day. These are the options most worth evaluating before you finalize your order.
Straight vs. Articulated Arms
Straight arms are the standard option for open-air or full-height entry points where overhead clearance is not an issue. In contrast, articulated arms are preferable when ceiling height is restricted, as they fold upward at a joint when raised to minimize the vertical space required. Depending on the model and configuration, passage height options include 84 inches and 98 inches.
- LED Lights: These enhance visibility at night and in low-light conditions. Options include static or flashing lights on the housing, plus LED strips under the boom that illuminate green when the arm is open and red when it is closed.
- Foam Edge and Breakaway Flange: The foam edge protection helps reduce damage to vehicles and equipment upon contact. The breakaway flange lets the arm detach cleanly on impact and reattach without hardware damage, lowering repair costs in high-traffic areas.
- Skirts: A boom skirt hangs below the arm to prevent pedestrians from slipping underneath. Over-climb skirts provide additional protection above the arm in higher-security locations. Both options come in varying lengths and can be paired with a support post.
- Pendulum Support: This feature is recommended for booms that are 15 feet or longer, helping to prevent arm sag. It folds flat against the boom when raised and remains out of the traffic path during normal operation.
Important Specs to Know Before You Buy
Getting these details confirmed before you order will prevent delays and make sure the equipment fits your site from day one.
- Lane Width: Determines how long the arm needs to be. Standard options are 10, 12, 15, and 20 feet.
- Clearance Height: Tells you whether a straight or articulated arm is necessary. Passage heights are available at 84 and 98 inches.
- Cycle Speed: Ranges from 0.3 seconds on the fastest toll units to around 4.0 seconds on standard access openers. Match the speed to your expected traffic volume.
- Duty Cycle: How frequently the arm cycles without rest. The Parking Pro is the benchmark at a rated 100%.
- Power Source: Standard AC or a 24V solar package, depending on what is available at the installation site.
- Housing Color: Orange, white, light grey, and dark grey are available across most models.
Safety and Installation Basics
Magnetic AutoControl barrier arm openers are designed to comply with UL 325, the industry standard for commercial gate and barrier operators. Most units include an integrated dual-channel inductive loop detector that senses vehicles in the lane, preventing the arm from closing on a car. Equipped with infrared obstacle detection and photo eyes, these systems stop or reverse the arm's movement if the beam is interrupted mid-cycle. The Parking Pro model also utilizes induction loops for tailgate detection, identifying following vehicles before they accidentally trigger a closure.
For installation, all current MicroDrive openers can be easily configured for either right-hand or left-hand mounting in under 10 minutes. To ensure long-term reliability, develop three maintenance habits: keep housing connections clean, periodically inspect the foam edge and flange hardware, and confirm the loop detector's sensitivity at least once a season.
