Low-density cartridge heaters are an
excellent, cost effective choice without
compromising quality for Original
Equipment Manufacturers (OEMs)
consuming large quantities of cartridge
heaters for their equipment.

The standard termination for low-density
cartridge heaters is Type F, consisting of
254 mm (10") internally connected flexible
lead wires with high temperature insulation,
UL approved for 300 or 600V service and
temperature rated to 250°C (482°F).
Note: To meet the requirements of your application we
offer over 40 standard termination styles to select from
that will solve many of the most common application
problems.
Ceramic end cap protects the cartridge
internally from outside contamination.
Resistance wire and lead wires are
mechanically spliced with heavy wall
nickel connectors for a positive electrical
connection.
Helically wound Nickel-Chrome resistance
wire is evenly stretched and strung through
ceramic insulators.
Alloy 304 stainless steel is used to provide
high temperature strength, good thermal
conductivity and resistance to oxidation
up to 650°C (1200°F). Alloy 304 is a
Nickel-Chromium stainless steel. For
immersion heating of corrosive solutions
contact OMEGA.
Specially selected grain size high purity
Magnesium Oxide (MgO) is used to fill all
remaining space inside the ceramic insulator,
thus increasing thermal conductivity,
dielectric strength and heater life.
Sheath is roll crimped over a 304 stainless
steel end disc. A mica spacer electrically
insulates the heater core from the end disc.
This style end seal is not moisture proof.
