'Quick and Simple Install DIN-Rail Mount with Wi-Fi Setup'

The 8 series, Nortech’s new flagship Parking Vehicle Detector addresses the market’s need for a slimline, advanced vehicle detection solution. The powerful architecture facilitates sophisticated algorithms ensuring robust and reliable detection every time. The relay and opto outputs are fully configurable, allowing for alarms and alerts on desired events. Nortech’s Automatic Frequency Selection (AFS) algorithms have been refined and optimised resulting in simplified setup and installation of complex multi-lane traffic sites.

Product features & benefits

The new DU800 wireless diagnostic unit allows for detector configuration and installation feedback of 8 series detectors on any iOS or Android device. This eliminates the need to adjust any mechanical interfaces once the unit has been installed. The DU800 also allows for vehicle profile streaming.

The new slimline, DIN Rail mount housing allows for more physical connections than the traditional relay base.

Like its forebears, the 8 series detectors simply work, offering peace of mind in even the most complex installation.

The TD180 supports a single loop with either relay or opto outputs.

Benefits

Slimline - Can be installed in even the most physically constrained environments
AFS - Automatic Frequency Selection (AFS) sets the optimal operating frequency to ensure minimal interference and maximum reliability
PowerFail Memory - In the event of a power failure, the TD180 will retain the presence of the vehicle when power is restored
Diagnostics - Comprehensive, wireless diagnostics allow for accurate diagnosis of loop and installation problems as well as configuration adjustments to eliminate issues using Nortech’s DU800 and Integr8 App

Fast-Response Single-Loop Detection for Traffic Counting and Signal Control

The 8-Series Single Channel Traffic Detector delivers industrial-grade vehicle sensing for traffic applications requiring fast response times and reliable single-loop detection. Engineered for traffic signal actuation, single-lane counting, and presence detection at isolated entry points, the TD180 provides sub-30ms detection response essential for accurate vehicle counting and responsive signal phase changes.

This detector excels in applications where single-loop monitoring meets the requirement—including traffic signal approach lanes, individual toll booth sensors, single-lane access points, and queuing detection at service windows. The compact DIN-rail housing fits inside roadside cabinets and space-constrained enclosures, while comprehensive electrical protection ensures continuous operation in exposed outdoor environments. Whether deployed at a drive-through lane, car wash entry, or pedestrian crossing approach, the TD180 delivers the same robust detection performance as its dual-channel counterpart in a cost-effective single-channel configuration.

Frequently asked questions

What is the difference between the TD180 single channel and TD280 dual channel?

The TD180 monitors a single inductive loop, making it ideal for single-lane applications like signal actuation or individual toll sensors. The TD280 monitors two loops independently, enabling speed measurement and directional detection.

What voltage options are available?

TD182/TD182P models operate on 90-230V AC, while TD184/TD184P models accept 12-24V AC/DC. All variants include polarity protection and comprehensive surge protection.

Can the TD180 be used for vehicle counting?

Yes, the TD180 can count vehicles passing over a single loop using pulse output mode. For directional counting or speed measurement, the dual-channel TD280 is recommended.

What protection does the TD180 have against electrical interference?

The TD180 includes loop isolation transformers, zener diode clamping, gas discharge tube protection, polarity protection, and 50-60Hz noise rejection—essential for roadside installations.

What is the inductance tuning range?

The TD180 self-tunes to loops between 20μH and 1000μH with sensitivity adjustable from 0.01% to 5% ΔL/L. Automatic Sensitivity Boost (ASB) is selectable for challenging loop installations.
