The LP D-TEK is a loop detector with a current draw of only 9 mA, purpose-built for solar-powered installations and applications with multiple accessories on the same power supply. The low draw doesn't compromise detection reliability.

Housing: anodized aluminium
Surge protection: zener diode + varistor
Operating temperature: -40°C to +82°C
At a barrier arm or gate in a remote location, without a mains connection, power consumption isn't an afterthought but a decisive factor in the entire design. A standard loop detector that draws relatively high current quickly means a larger solar panel and a heavier battery than should be necessary. The LP D-TEK is specifically built to reduce that problem, with a current draw of only 9 mA in both standby and detect modes.
In a solar-powered installation, the total power draw of every connected component directly determines how large the panel and battery need to be to keep the system running year-round, including short winter days with limited sunlight. Every loop detector, every sensor, and every relay contributes to this total. A detector drawing 9 mA instead of the usual higher level can make the difference between a compact, affordable solar panel and a significantly larger, more expensive installation.
Low power consumption isn't only valuable with solar panels. At a gate operator with multiple accessories all drawing power from the same supply, for example a combination of loop detectors, photo-eyes, and warning lights, the total power draw can reach a level where the power supply itself becomes a limiting factor. The LP D-TEK's low current draw leaves more headroom for additional accessories without needing to upgrade the power supply.
The low power draw doesn't come at the cost of detection performance: the LP D-TEK offers the same wide compatibility range for loop inductances (20 to 2000 µH) and ten adjustable sensitivity levels as other loop detectors in the range. The anodized aluminium housing protects against surges via a zener diode and varistor, and the detector operates reliably across a temperature range of -40°C to +82°C.
Like other loop detectors, the LP D-TEK can be configured for fail-safe or fail-secure operation, depending on the application's requirements. For a remote location where both reliability and energy efficiency matter, that flexibility is just as relevant as it is for a mains-powered installation.
The LP D-TEK is mainly used at solar-powered barrier arms and gates in locations without a mains connection, such as rural access roads, temporary construction sites, or remote parking areas. It's also a logical choice for any installation with multiple accessories on the same power supply, where energy efficiency benefits the reliability of the system as a whole.
