Lead Wires/Hookup Wires
Lead wire or hookup wires are a single insulated conductor used in industrial equipment for internal wiring, control panels, and instrumentation signals. Tempsens manufactures a range of lead wires from various insulation materials like PVC, LSZH Polymer, PTFE, FEP, ETFE, HFFR Polymer etc. They are made from electrolytic grade bare copper, or tinned copper in various configurations as solid, multistrand or flexible with varying conductor sizes from 32 AWG to 6 AWG. Our lead wire material complies with IS standards as IS 694, IS 8130, IS 5831: 84, which ensures reliable performance across laboratories, home appliances, chemical plants, and electrical panel applications.

FAQ
Frequently Asked Questions
Find answers to frequently asked questions related to Lead Wires/Hookup Wires.
Lead wire provides connectivity between instrumentation(thermistors, resistors) and electrical components(LED, heaters) in places such as control panels, chemical plants, laboratories, and industrial heating systems that require specialized insulation and high temperature resistances for their use.
No. The lead wire is a connecting wire used in industries insulated with materials like PVC, PTFE polymers etc.
A lead wire’s longevity is affected by many things: operating temperature, conditions of the environment, and the insulator used. Under rated operating conditions, the PVC insulated lead wires from Tempsens will generally last for 15 to 20 years, whereas PTFE and FEP insulated lead wires may very well exceed 25 to 30 years of lifespan.
Lead Wire is frequently referred to as Hookup wiring, Connection Wiring or Conductor Wiring. Depending on the settings of various temperature measuring applications, the lead wire may be identified as Extension Wire or Compensation Cable.
The lead wire price is determined by the conductor size, insulation material, and specifications. The quality of lead wires offered by Tempsens is of the highest standard at prices that are competitive with the marketplace, and their quotation for each type of lead wire will be provided upon request.
