Owing to their small cross-sectional dimensions, MicroCoils are most often connected at both ends and do not permit the addition of a thermocouple. We prefer to use nickel as the sheath material here because it combines the best thermal conduction properties, high corrosion resistance and excellent deformation properties. To ensure that the standard 1000 mm PTFE-insulated connection cable can be positioned at one end, despite the standard two-ended connection of the element, in most cases the MicroCoil is formed into a hairpin shape and wound/laid in a bifilar (parallel) format. Our unformed MicroCoils are also supplied in the hairpin bend shape as standard.

Attention: Elements which have been bent once, must not be altered anymore. The connection area as well as the first 5 mm unheated area must not be deformed at all.
Compact MicroCoils with single-ended connection
MicroCoils from Ø 1.8 mm or 1.3 x 2.3 mm are also available with the supply at one end (Compact type) for higher power densities. This allows the electrical power to be concentrated still further. Because of the confined space available and thus the extremely thin heating element wires, however, the power can only be increased proportionately to length for heated lengths of up to 600 mm.
MicroCoils with complex winding geometries
The outstanding plasticity of our nickel MicroCoils enables us to achieve highly complex winding geometries - and not only for contact heating but also for convection-based air heating applications.
