RS PRO Cartridge Heater Heating Element, 4in Length, 300W Power, 120V AC, RoHS Compliant 860-6839

RS PRO 860-6839 Cartridge Heater Heating Element is a precision heating solution designed for industrial, process control, and automation applications where close thermal regulation is required. This 4-inch cartridge heater operates at 300 watts power and is supplied with a 120 volt AC power rating, making it ideal for localized heating needs.

The heater incorporates a nickel-chromium resistance wire that ensures long service life. Its high impact ceramic cap withstands high vibration and elevated temperatures up to 450°C, making it suitable for harsh industrial environments. Lead wires insulated with fiberglass extend durability and safety with a length of 10 inches, protected further by a TIG welded end disc that prevents contamination and moisture ingress.

Cartridge heaters like this utilize low to moderate watt density helical wire coils on a ceramic former or high watt density elements to achieve efficient heat conduction. The swaged sheath design improves heat transfer for effective localized heat output. For best performance, it is advised that temperature sensing and control elements are used alongside the heater.
