Dayton Type K Thermocouple Jack

The Dayton 36GL04 is a yellow Type K thermocouple jack built for HVAC temperature sensing. Its glass-filled thermoplastic housing and nylon sheath protect Alumel and Chromel contacts rated to 428 degrees Fahrenheit. The two-pin standard plug suits technicians who need a reliable connection for Type K probes in heating and cooling systems.

Replaces worn or damaged Type K jacks

Swap this jack when an existing connector shows melted housing, corroded pins or intermittent readings. The upgrade is worth it if the old part no longer holds its 220 degrees Celsius rating or if the sheath has cracked. It fits the same standard Type K plug footprint so no wiring changes are required.

Verify sensor type and temperature range

Confirm the probe is Type K before ordering; other thermocouple calibrations will not match the Alumel and Chromel contacts. Check that the application stays within the 428 degrees Fahrenheit limit. Ensure the panel cut-out matches the standard two-pin jack dimensions already in use.

Questions about this item

What panel cut-out is needed for the yellow Type K thermocouple jack?

The jack uses a standard two-pin plug format that fits common panel openings for Type K connectors; check your panel template for the exact cut-out dimensions.

How do I wire the Alumel and Chromel contacts correctly when installing the jack?

Insert the negative Alumel lead into the larger pin socket and the positive Chromel lead into the smaller pin socket; reversing them will give inverted temperature readings.

When should the glass-filled thermoplastic jack be replaced due to heat exposure?

Replace the jack if the yellow housing shows discolouration, cracking or softening after repeated cycles near the 220 °C (428 °F) maximum temperature rating.
