  • Environmentally Friendly Cadmium-Free Liquid Crystal Polymer Material
  • Mating Connector, Cable Clamp, Write-On Pads and Ground Strap Included!
  • Ground Strap Connection Provides Protection Against Electrical Noise
  • Ground Strap Provides Additional Mechanical Rigidity
  • Write-on Area for Easy Identification on Female Connector
  • Compatible with Standard Style Probes and Connectors

Combination Interior Screw Heads
The foolproof connector! Side and interior screws have combination heads, so you can use either a flathead or Phillips screwdriver. And, it's captive, so it won't fall out.

Protective Ground Strap
Each connector pair includes a protective ground strap. Extra straps, Model GS-GMP-10 (pkg. of 10), £2.

    The OMEGA low noise thermocouple probes and connectors maintain an electrical connection from the sheath of the probe, through the connectors, all the way to your instrumentation. This system assures high accuracy measurements, providing protection against electrical noise. The external strap maintains the electrical connection of the ground wire, and also strengthens the mechanical connection between the two connectors. The female connector features a handy write-on area, for easy identification.
Plastic Write-On Pads
For applications not requiring the external ground strap, plastic write-on pads are included with each probe and connector to provide additional write-on areas.
