Chromalox Big Red Book

Components

STRS .315" Dia. Round Cross-Section Single-End Terminal • Steel Sheath • 150 - 2,050 Watts • 120 and 240 Volt • 4 - 20 W/In 2 • 750°F Max. Sheath Temp. Applications Molds and other heat-transferring metal parts and air heating applications. Immersion heat- ing with flange, screwplug, threaded fitting or other means of mounting. Advantages Elements with both terminals at one end, in dies, can simplify wiring in many cases. Use slim elements to concentrate heat into a con- fined area, taking up less space than a U-shaped element with terminals at each end. Features Construction — Similar to the standard Chromalox tubular design, except that both terminals of the embedded resistor wire are at one end of the element. 10" lead wires have silicone-impregnated Fiberglas ® sleeves and are attached to the terminals inside a ceramic terminal bushing. Sealed End for Immersion Heating on end opposite terminals is provided on all stock, single-end elements. When ordering non- stock elements for use as immersion heaters, specify “sealed end”. Work Temperatures — See Tubular Heater Overview section. Bending — Generally not recommended for single-end elements.
