No limit switch – smart processor auto- detects open and close position for higher accuracy. Combination of unique lever design and smart motor control allow swift arm movement that reduces bouncing at end position.

Optimal speed.
Able to fully lift up a 3 meter arm in between 1 to 6 sec depends on the models. This allows smoother and more efficient traffic flow.

Heavy Duty.
AC based motor is stronger and maintenance free (no need to change carbon). Compressed counter balance spring avoids possibility of spring over-stressed and break due to high volume continuous open/lose cycle.

Arm will auto-reverse when hitting an obstacle during closing. Photo beam can be added to auto-reverse the arm ahead of time before hitting approaching vehicle or human. BR510, BR518 and BR530’s arm will auto-fall out if hit by vehicle to avoid breaking the arm and minimize damage to the vehicle. Traffic light (red & green) can be added to indicate permission to pass through and further enhance safety usage. Built-in MSB to protect against any electric hazard.

Housing is polished, phosphorized and further finished with plastic coating to ensure long lasting bright colors.

Arm is self-locked in any position to avoid unauthorized person to manually open/close arm. All internal parts inside housing is protected by cam lock to avoid tampering.

User Friendly.
Clutch can be conveniently released without opening casing. Arm can be easily lifted or closed by hand after clutch is released. More intuitive control – 3 separate input for arm up, stop and down.

Easy maintenance.
Damaged barrier arm can be replaced easily. Epoxy powder paint will keep the unit looking clean and new for years.
