Siemens SLD4 Inductive Loop Detector


Offering excellent detection accuracy with all popular traffic control equipment, Siemens’ all-new self-tuning SLD4 loop detector is fully compliant with UK specification TR2512.
Designed for maximum reliability and using the latest inductive loop detection algorithms, the SLD4 complements the company’s full range of traffic detection options which includes both Selective Vehicle Detection and above-ground detection of vehicles and pedestrians.

The new detector offers fully automatic set-up features ensuring optimum performance without interference. This represents a significant improvement over manual setting of frequency and sensitivity parameters which can often be a challenge, with failure to achieve this correctly causing detectors to ‘chatter’ or otherwise fail to operate.

Providing four separate detection channels, the new detector offers full solid-state outputs for maximum reliability. For challenging or special applications, a new PC support tool enables many aspects of the detector’s functions to be accessed for specific deployment scenarios.

The new detector may be powered from either AC or DC supplies. Its low power requirements with operation possible at voltages as low as 10V DC, makes support within battery powered equipment a viable option where needed.

When fitted with other SLD4 detectors, all units are able to communicate with each other enabling critical parameters to be set automatically. Once all the detectors are fully set up LEDs on the front of each detector flash in synchronism to signal that automatic setup has been achieved. Manual set-up is also possible, with sensitivity level, presence time and frequency selection being offered via DIL switches.

A summary of features includes:

  • Four detection channels with solid state outputs for maximum reliability
  • Fully automated set-up
  • Self-tuning operation
  • High detection accuracy
  • Low power operation
  • Standard 3U Eurocard format
  • Designed to meet UK specification TR2512
