SECTION 1 INTRODUCTION

1.1 General Description

The OMEGA®Multi-Pin Thermocouple Connectors provide a sturdy
and efficient means of joining multi-wire thermocouple cables. They
can be used with OMEGA Multipair Extension Cable for rapid,
convenient connection and dismantling of apparatus without handling
individual sensors.

The design utilizes a combination of resilient and rigid dielectric
insulators to eliminate internal air voids and prevent the passage of air
and moisture into or through the connector. Connectors can withstand
ambient temperatures up to 392°F (200°C) contributing to an extended
connector life.

The OMEGA Multi-Pin Thermocouple Connectors do not carry a MIL
spec. number; however, they do meet the performance requirements of
MIL-C 26500E and are intermateable with MIL-C 26500 connectors.

1.2 Features

• Thermocouple alloy pins and sockets

• Air and moisture resistant connection

• Rated to 392°F (200°C)

• Removable crimp contacts

• Accepts 20-24 gage wire

• Aluminum shells

• Black anodized finish

• Threaded coupling

SECTION 3 OPERATION

3.1 Multi-Pin Connector Bodies

The contact cavities in the connectors are identified with a spiral guide
line indicating cavity sequence (see Figure 3-1). The first and last
cavities are numbered and every tenth cavity is bracketed. The number
of available cavities are 5, 12, 24, 41, and 55.
