Jedrek 24V Vehicle Loop Detector 50m Coil

SKU CH-Q0GR-9CEA1

Detects vehicles via a 50-metre inductive loop coil and provides relay output for gate or barrier control

  • TypeDoor / Window Sensor
  • Operates on 24V supply with ±15% DC tolerance
  • Adjustable sensitivity in 4 increments for precise detection
  • 10ms reaction time ensures rapid vehicle response
  • Output relays rated 240V/5A for reliable switching
  • Functions from -20°C to +65°C operating range

Purpose and fit

The Jedrek 24V Vehicle Loop Detector monitors traffic presence through a 50 metre induction coil embedded in the road surface. It suits gate automation, barrier control and car-park entry systems that require a hard-wired vehicle sensor rather than a camera or infrared beam.

Thermals noise and power

The unit draws 4.5 VA from a 24 V supply with AC tolerance of +10% / -15% and DC tolerance of ±15%. It operates reliably between -20 °C and +65 °C and can be stored down to -40 °C. Two output relays rated at 240 V / 5 A switch silently with a 10 ms reaction time.

Accessories and software impact

The 50 metre coil wire is included, allowing a complete loop plus up to 20 metres of twisted connection wiring at a minimum of 20 turns per metre. Adjustable sensitivity in four increments lets the installer tune detection for the specific loop inductance, which should fall between 50 H and 1000 H.

Questions about this item

How do I install the 50m induction coil wire and what is the most common wiring mistake?

Lay the 50m coil in the detection zone, twist the lead-in wires at least 20 times per metre, and keep the total lead-in length under 20 metres. The step often missed is achieving the required twist rate, which keeps loop inductance inside the 50H to 1000H range.

What maintenance or replacement will the detector and coil need over time?

The solid-state detector has no moving parts and requires no scheduled maintenance. The 50m coil wire may need replacement if the insulation is damaged by excavation, frost heave or rodent chewing, which would shift inductance outside the 100H to 300H ideal window.

What limit appears first when the loop is permanently covered during sustained use?

The signal holding time switches from unlimited to a fixed 10 minutes once the loop stays continuously covered, so permanent vehicle presence is the first sustained-use limit the unit enforces.
