The MTP 3-prong is miniature-sized, 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. Negative pins and sockets 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. Appearance of “Omega” logo may vary (it may be stamped onto or molded into the connector).

Note: Minor discoloration of connector may occur between 150°C (302°F) and 180°C (356°F). Electrical properties are not affected.

What is the minimum dia/AWG of wire this MTP connector can hold? What is the tightening torque recommended?

Asked by: Santhosh
Thank you for your inquiry. The recommended wire gauge is 26 AWG. The torque spec on the connector is 3.2 inch-pounds
