Type E Insulations

A polyimide sleeve is epoxied over the weld joints (as

in the Type B insulations) and then multiple conformal

dip coatings are applied (as in the Type C insulations)

for fully immersible assemblies. The same insulating

material options are available.

Insulated Extension Leads

The standard insulated extension lead sub assembly

has 38 gauge 0.004 in (0.10 mm) diameter, nickel alloy

200, bifilar, heavy ISONEL insulation over conductors

and a length of 6.5 (1.98 m) ±1/2 ft (±0.15 m). Other

options, including any specified by the customer, are

available upon special order.

Insulation

• HeavyISONEL:foruseto356°F(180°C),excellent

abrasion resistance, our standard coating.

• Polyurethane:foruseto221°F(105°C),easily

stripped, excellent solderability.

• Polyimide:foruseto446°F(230°C),excellentthermal

and dielectric properties, (not recommended for

water and certain other conductive fluids)

Construction

• Bifilar:Parallelconductors,ourstandard

• Single:Individuallyinsulatedlead-wires

• Twisted Pair: 0.1 in (2.54 mm) lay typical

Length

6.5 ft (1.98 m) ±0.5 ft (±0.15 m) is standard, specify

other lengths as desired. All lengths over one foot are

supplied on a plastic bobbin with the wires wrapped so

that the thermistor end is removed last.
