Industrial Spark Ignition Electrode Assembly, 200mm

R.K. Instruments & Controls stocks this Industrial Spark Plug / Ignition Electrode Assembly, a threaded, hex-bodied ignition electrode built for direct mounting and sealing into a burner or flange via its hex bushing, unlike the site's bare ceramic-rod custom and ZE-series electrodes. The assembly has an overall length of 20.0cm (200mm), with the mounting body and upper plug section measuring 85.6mm, an upper ceramic insulator diameter of 13.3mm and a lower insulator-neck diameter of 7.5mm below the threaded section. The front ceramic sleeve, which houses the exposed electrode tip, measures 4.9cm (49mm) in length with a 10.6mm diameter. The top terminal is a standard threaded/snap fitting for the HT ignition cable connector, and the electrode contacts via a disc-style tip configuration. Construction is high-alumina ceramic insulators over a stainless steel/metallic rod, with a metal hex body and terminal for direct threaded installation — a robust, self-contained spark-plug-style ignition electrode for burner and boiler applications where a threaded mounting (rather than a loose ceramic rod) is required.
