Safety Barrier Loop Detector | Dual Channel, Prevents Pinching & Durable & Secure Entry/Exit

Automated barriers and gates are essential for controlling access and managing traffic flow in countless facilities, from parking garages to industrial sites. However, their operation must prioritize safety above all else. Accidental closures can lead to vehicle damage, injuries, and costly liabilities. The JUTAI Dual Channel Safety Barrier Loop Detector is specifically engineered to mitigate these risks, providing enhanced safety features, robust durability, and reliable control for secure entry and exit points.

Prevent Pinching Accidents with Advanced Dual Channel Logic

The core safety advantage lies in the dual-channel technology. Unlike basic single-loop systems, this detector utilizes two independent inductive loops and sophisticated logic. One channel typically manages the primary activation or opening of the barrier, while the second acts as a dedicated safety presence loop. This configuration allows the system to reliably detect if a vehicle remains within the barrier's path, actively preventing the gate or barrier arm from closing prematurely. This crucial anti-pinching function, powered by JUTAI's precise detection technology, significantly reduces the risk of accidents and enhances user confidence at your access points.

Built for Longevity: Durable Performance Day In, Day Out

Access control points often face heavy use and exposure to varying weather conditions. The JUTAI Dual Channel Loop Detector is constructed with durability in mind. Its robust design ensures reliable operation even in demanding outdoor or industrial environments. Built from quality materials and engineered for resilience, it withstands the rigors of daily operation, minimizing downtime and maintenance requirements. This focus on durability ensures your safety system remains operational and effective long-term, providing consistent protection and uninterrupted access control.

Secure Entry and Exit: Reliable Control Where It Matters

Beyond preventing accidents, this dual-channel detector contributes to overall site security. The two-loop system provides a more reliable confirmation of vehicle presence and passage compared to single-loop setups. This enhanced detection accuracy helps ensure that barriers operate correctly for authorized entries and exits, preventing issues like tailgating or unauthorized passage attempts. By providing dependable vehicle detection logic, the JUTAI detector integrates seamlessly into your access control system, reinforcing secure operations and giving you greater control over who enters and leaves your premises.

Invest in Safety and Security with JUTAI

Don't compromise on safety at your automated barriers and gates. The JUTAI Dual Channel Loop Detector delivers the anti-pinch protection, long-lasting durability, and secure access control logic you need. Protect people, prevent damage, and ensure reliable operation with a trusted solution.

Feature

• 3. Diagnostic Capabilities & LED Indication
  • Comprehensive diagnostics capabilities enable accurate diagnosis of loop and installation problems and shows through the LED state, ensuring optimal performance and reducing downtime.

• 4. Selectable Presence Time
  • The output of the presence relay can be selected to limit a detect output to a fixed time (greater than 30 minutes) while a vehicle remains on the loop, providing flexibility in traffic management.

• 5. Automatic Sensitivity Boost (ASB)
  • This feature reliably detects large truck-trailer combinations and high-bed vehicles by automatically boosting the sensitivity to maximum upon vehicle detection, ensuring accurate identification.

• 6. Automatic Environment Drifting Compensation
  • Loop detectors (or other sensors) automatically adjust and calibrate themselves to changes in environmental conditions, maintaining detection accuracy and stability despite varying weather and environmental factors.

• 7. 17 Dip Switch Setting
  • The dip swich design on the shell makes the setting of loop detector easier and clearer, which is very user-friendly for users. Users can set all the functions first and then install the loop detector.

• 8. Dual Channels work Cooperatively or Independently
  • Dual channel loop detector can be used as two single channel versions, Supports two independent detection channels.
  • Also allowing for the simultaneous monitoring of multiple loops, loop detector has the ability to recognize direction in single-channel applications. enhancing the flexibility and accuracy of vehicle detection.

• 9. Anti-crosstalk interference.
  • Through the dip Switch, the frequency of the loop detector can be adjusted to prevent crosstalk interference caused by the installation of two loop coils too close.
