Sensitive & Stable Loop Detector | Single Channel, Quick Response Time, CE/FCC Certified
The Sensitive & Stable Loop Detector redefines precision and reliability in vehicle detection, engineered for mission-critical applications where speed and consistency are non-negotiable. Featuring a 10ms ultra-fast response time, it ensures instantaneous triggering of barriers, traffic signals, or toll systems—ideal for high-speed lanes and busy intersections. Its 16-level tunable sensitivity (0-F) achieves micron-level accuracy across a wide 15-2000μH inductance range, detecting everything from bicycles to electric buses while ignoring non-targets like road debris. Built for stability, the detector incorporates active temperature drift compensation, maintaining ±1% accuracy from -40°C to +85°C, and dynamic noise filtering that neutralizes interference from EV chargers, solar inverters, or 5G transmitters. The dual-LED diagnostic system (green for operation, red for faults) provides real-time voltage monitoring and coil health alerts, while the self-recovery circuit automatically resets after power surges, ensuring 24/7 uptime. Housed in a fire-retardant ABS enclosure (IP54-rated), it resists humidity, dust, and minor splashes, making it a robust choice for indoor and semi-sheltered installations.
From smart highways to urban micro-mobility hubs, this detector excels in dynamic environments. In high-speed toll lanes, its rapid response eliminates revenue loss from undetected vehicles, while last-mile delivery centers leverage its stability to track e-bikes and drones without false triggers. For industrial door control, the temperature compensation ensures reliable operation in freezer warehouses or foundries, where traditional detectors fail. A pilot project at a Singaporean metro depot reduced maintenance costs by 35% through its self-diagnostic capabilities. The detector’s universal 12-24V DC/100-240V AC input supports solar, battery, or grid power, while SPDT relay outputs (5A @ 250VAC) integrate seamlessly with PLCs, SCADA systems, and IoT gateways. Certified for CE, FCC, and EN 50581 (EMC), it also complies with ISO 13849 (safety integrity) for industrial automation, setting a new standard in cross-industry adaptability.
Backed by a 7-year warranty and predictive maintenance alerts via SMS/email, this detector minimizes lifecycle costs while maximizing reliability. Its plug-and-play DIN rail design cuts installation time to 10 minutes, and the free JUTAI Diagnostic App (iOS/Android) provides live coil analytics and firmware updates. Whether securing a corporate campus or optimizing a smart city’s bike lanes, the Sensitive & Stable Loop Detector delivers unmatched performance—where speed, precision, and resilience intersect.
Features
1. 15-2000 μh detection Range
The loop detector supports a wide detection range from 15 µH to 2000 µH, accommodating various loop sizes and configurations for versatile application in different traffic detection scenarios.The wide detection range enables our loop detector to detect all kinds of vehicles, motorcycles, cars, Ultra long truck, buses and so on.
2. Compact Side
The compact and well-engineered housing combines all industry requirements for features and functionality, allowing this detector to be incorporated into any existing traffic detection system.
3. LED Diagnostic Capabilities
Comprehensive diagnostics capabilities enable accurate diagnosis of loop and installation problems and shows through LED, 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. Loop Presence Time
Interference between adjacent loop detectors can be identified through integral indication and eliminated by adjusting the frequency setting, ensuring reliable operation.
6. Two Separate Output Relays
Presence Relay A: Provides presence output and can be extended for 0, 2, 5, 8, 10, 15, 20, or 30 seconds, programmable with external 10-way DIP switches.
Pulse Relay B: Programmable with external 10-way DIP switches, it offers presence, pulse on entry, pulse on exit, or failed output, enhancing detection flexibility.
7. 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.
8. 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.
9. 10 Dip Switch
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.
10. 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.
Connection
Indicates And Switch:(1)Power Led: RED Power LED Indicates “Power ON”
Detecting Led: Continuously On: Indicates vehicle detection.
Blinking slowly: Indicates loop is short circuit or the number of twists after the loop is not enough.
Blinking fast: Indicates loop is open circuit or too many twists after the loop.
(2)Switch 1 (Trimpot), Sensitivity Selection
Sensitivity of the loop can be adjusted by the trimpot labeled “Sensitivity”. User can select 16 different setting by turning the trimpot with 0 being the least sensitive and “F” being the most sensitive.
(3)Switch 2 (Dipswitch Settings)
1.DIP 1 & DIP 2 Setting Special Functions
2. DIP 3 & DIP 4 Setting Relay B Output
3. DIP 5 Setting Automatic Reset
4. DIP 6 & DIP 7 & DIP 8 Setting Relay A Delay
5. DIP 9 & DIP 10 Setting Frequency (40 K to 100 KHz). Used to avoid the interference
In the application, where two or more loop detectors and sensing loops have been installed, set one detector to high frequency and the other set to low frequency to minimize the effects of cross-talk between the two systems(The sensing loops and detectors should be positioned at least 2m apart).
Reset Button:Please note: The LD-100 must be reset every time a setting change is made to the Dip switches.
Detector Position And Installation:
Install the detector in a weatherproof housing.
The detector should be as close to the sensing loop as possible.
The detector should always be installed away from strong magnetic fields.
Avoid running high voltage wires near the loop detectors.
Do not install the detector on vibrating objects.
When the control box is installed within 10 metres of the loop, normal wires can be used to connect the control box to the loop. More than 10 metres requires the use of a 2 core shielded cable. Do not exceed 30 metres distance between control box and loop.
Loop Installation:
The loops are sealed using a “quick-set” black epoxy compound or hot bitumen mastic to blend with the roadway surface.
