The OMEGA
TM
GMP and HGMP miniature lownoise connectors are designed to provide easy
connection of ground wires to OMEGA
TM
probes
and extension wires. The drain wire of a 20 AWG
twisted shield cable or the shield of the overbraided
wire is crimped and held in place by the their
internal hardware. They have excellent thermal and
electrical characteristics to assure high accuracy.
Each connector includes write-on windows for front
and side. An External ground strap to maintain
the electrical connections of the ground wire and
strengthen the mechanical link between connectors.

The foolproof connector! Interior and side screws have
combination heads, so you can use either a flathead or Phillips
screwdriver. And they’re captive, so they won’t fall out.

J, K, T, E, R, S and B are ANSI designations. OMEGALLOY is generically known as Nicrosil-Nisil. ANSI color models shown.
Note: Type U (uncompensated) connector bodies are used with Type B thermocouples (Pt/6%Rh-Pt/30%Rh).
Ordering Examples: HGMP-J-M, high-temp, low-noise, Type J calibration, male connector.
HGMP-K-F, high-temp, low-noise, Type K calibration, female connector.
Note: Each connector
is supplied with a
write-on window for
the face and side.
The ground strap
replaces the side
window and maintains
the electrical
connection through
the connector.
