Product Overview

- Wire Type Solid, Stranded
The OTP 3-prong is standard sized with round pins and is available color-coded for thermocouple or white for uncompensated 3 wire and 3 pin TC connectors. These quick disconnect plugs and jacks provide reliable connections between thermocouple, RTD or thermistors and extension wires. The color-coded bodies are molded of high performance glass-reinforced nylon. Tubular plug prongs and collet-type jack inserts have low mass and reduce temperature gradients. Negative prongs and inserts are larger than positives to insure proper polarity upon connection. This is a standard feature on all OMEGA connectors. Recommended for most applications requiring three-wire circuits, including shielded thermocouples, thermistors, and RTD's. Especially useful for continuing thermocouple shield leads through panel jacks. Will withstand ambient temperatures to 220°C (425°F). High-impact construction.
For strain relief and other accessories see Related Links below. Appearance of “Omega” logo may vary (it may be stamped onto or molded into the connector).

Good Robust Connectors
We use these connectors with Panel Mount RTD's and these have proved to make good flawless connections even under vibrating conditions.

Uncompromised quality Thermocouple connections
High quality connectors for thermocouple extensions. I wouldn't expect any less from Omega.
The design and quality I have some to expect and get when purchasing thermocouples and connectors.

Is an anti-oxidation compound such silver conductive grease or NOALOX permitted on the RTD connector pins? We are experiencing signal loss and errors.
