HySecurity MX3705, ARM MNT ASSY, BREAKAWAY, SA
The HySecurity MX3705 breakaway arm mount assembly is a mechanical protection component for supported StrongArm barrier arm systems. Its job is to connect the arm to the operator while allowing controlled release during an impact or excessive force event. This helps reduce damage to the arm, mount, and operator structure, especially in parking, access-control, and perimeter security lanes where vehicle contact can happen. A breakaway mount should not be ignored after it trips; the arm, bracket, pivot hardware, stop switch if present, fasteners, and alignment need to be checked before returning the lane to service. Fitment depends on the arm style and StrongArm assembly, so do not substitute based on appearance alone.

Technician Note
This is an OEM HySecurity service part. Match the part number, operator model, original assembly, and current parts diagram before ordering. Similar HySecurity parts can look close but may use different dimensions, wiring, connectors, handing, or operating functions.
Before Ordering Checklist
- Confirm the HySecurity operator model and product family.
- Compare the original part number or parts diagram to MX3705.
- Check related components for wear, damage, corrosion, fluid leaks, heat damage, or misalignment.
- Verify voltage, wiring, connector style, mechanical size, handing, and hardware where applicable.
- Do not bypass safety devices, circuit protection, or required entrapment protection while diagnosing the operator.
Professional Advisory
Gate and barrier operators can move heavy equipment and may include stored energy, hydraulic pressure, battery power, and high-voltage circuits. If the system is damaged, leaking, repeatedly tripping a breaker, moving unpredictably, or missing required safety devices, have it inspected by a qualified gate technician before returning it to service.
Product Questions and Answers
What is the purpose of MX3705?
MX3705 provides a breakaway mounting point for supported HySecurity barrier arms to help reduce damage during impact.
Can the arm be reused after a breakaway event?
Possibly, but the arm, mount, pivot hardware, stops, fasteners, and alignment should be inspected before reuse.
Is MX3705 the same as an articulating arm pivot?
No. MX3705 is a breakaway arm mount assembly. MX3670 is an articulating arm pivot reference.
Does it fit every StrongArm model?
No. It should be matched to the specific StrongArm or SA arm assembly and parts diagram.
Is this a safety device that prevents vehicle damage?
It helps reduce operator/arm damage during impact, but it is not a substitute for traffic control, signage, safety devices, or proper lane design.
