Dayton 36GK90 Type K Thermocouple Jack

This yellow miniature jack accepts Type K thermocouple sensors for temperature measurement up to 428 degrees Fahrenheit. The glass-filled thermoplastic housing holds flat Alumel and Chromel contacts inside a nylon sheath. It suits HVAC technicians and maintenance teams who need a reliable miniature connector for Type K probes.

Sustained-load behaviour

The jack is rated for continuous exposure to 220 degrees Celsius without degradation of the housing or contact materials. Glass-filled thermoplastic maintains dimensional stability at the upper limit, while the Alumel and Chromel contacts preserve signal integrity through repeated thermal cycles. The nylon sheath adds mechanical protection during prolonged installation in ductwork or equipment panels.

Compatibility checklist

Verify that your sensor uses a Type K miniature plug with flat pins before ordering. Confirm the probe sheath diameter fits the nylon opening on this jack. Ensure the application temperature stays within the 428 degrees Fahrenheit maximum. This connector is not suited for other thermocouple types or standard-size plugs.

Questions about this item

Does the yellow Type K jack get hot or draw power during continuous use?

The jack is a passive connector rated to 428 °F (220 °C); it generates no heat and draws no power.

What mating plug is needed for the mini-jack to work?

A Type K mini plug with flat pins — standard yellow mini connector — must be supplied by the user.

Can the glass-filled thermoplastic housing and Alumel/Chromel contacts mate with older Type K probes?

Yes — any Type K probe with a standard mini plug will connect; the contact materials match Type K thermocouple alloys.
