Formula for Determination of Watt Density

Watts/sq.in. =

Optional Terminations

Type SSA: Parallel at one end. Heated length (“C”) is 3/4″ longer.

Type SO: One each end. Heated length (“C”) is 1″ shorter.

Type SF1: Flexible high temperature insulated leads. Specify length. Opposite end of unit may be standard closure with mounting hole or any of the optional closures. (Blunt end, XS54, shown) Suitable for use to 480V. Lead end may be sealed for moisture resistance.

Optional End Closures

XS-54:Blunt end. Welded each end with no mounting holes. May be used with Type OF, SSA, or SO terminals. Heated length (“C”) is 3″ longer.

XS-83:Short crimp. At each end with no mounting holes. May be used with Type OF, SSA, or SO terminals. Heated length (“C”) is 1″ longer.

XS-84: Secondary insulating bushings. Required when units are connected in series on voltages above 300V. Sheath must be isolated. Requires enlarged (1/2″ x 3/4″) mounting hole each end. May be used with Type OF, SSA, or SO terminals.

Tolerances

Width: 1.500, ±.020 Length: Up to 24″, ±1/16″
24″ and over, ±1/8″ Thickness: .375, ±.020
Wattage tolerances are held to +5%, -10% at rated voltage.

Voltage

Standard voltages are either 120sV or 240V. Other voltages are available.

How to Order

After determining the wattage required and the line voltage available, determine the physical space available for heaters and the number of heaters required. Review Strip Heaters In-Stock. Specify:catalog number, wattage, voltage, termination, and special features if required.
