Honeywell sensor cable 2-wire 500mm, 7225001

This article is a 2‑wire sensor cable, 500 mm long, from Honeywell. It is listed under ignition cables and connectors. Parts of this type are used to carry electrical signals or high‑voltage ignition current between the burner control, the ignition transformer and the flame sensing components. The silicone insulation provides resistance to the high temperatures and voltages present near the combustion head. When selecting a replacement, the number of conductors, the cable length and the termination pattern must match the original. A damaged or hardened insulation on such cables can leak the spark to earth or cause intermittent flame‑signal loss, leading to burner lockout. Check that the existing cable is not worn before diagnosing a faulty transformer or control.
