The ASTEEL INHE160E is a compact, single-loop inductive vehicle detector that senses metal passing through a magnetic loop by detecting inductance changes. It operates from a 24 V power supply (AC or DC) at 50 Hz and consumes about 3.5 W, with a relay output rated for 1 A at up to 230 VAC. The unit offers three sensitivity settings and a pulse duration of 0.8 seconds, with a relay mode described as permanent so the relay remains in the active position while a vehicle is within the loop. Common applications include gate and barrier control and other access‑control or traffic-detection scenarios that rely on a 1‑loop detector.
