Black glass-filled thermoplastic thermocouple jack with two iron and constantan pins

Dayton

Dayton 36GL03 Thermocouple Jack Type J Black

SKU CH-BAGA-1B2QW

Type J thermocouple jack with glass-filled thermoplastic housing and iron/constantan contacts rated to 428 °F

  • ColorBlack
  • Type J jack handles 220 °C continuous use
  • Glass-filled thermoplastic body resists heat and impact
  • Constantan and iron contacts match Type J thermocouples
  • Nylon sheath protects wiring from abrasion
  • Standard two-pin layout fits existing panels

Product Identity

This Dayton Type J thermocouple jack is a two-pin connector built for temperature-sensing circuits that use iron-constantan thermocouples. It suits technicians and OEM assemblers who need a standardised jack for process control, HVAC equipment or laboratory wiring.

Temperature and Wiring Limits

The jack is rated to 220 degrees Celsius (428 degrees Fahrenheit), so the circuit must not exceed that temperature at the connector body. Its glass-filled thermoplastic housing and nylon sheath are specified only for Type J thermocouples; using other thermocouple types will produce incorrect readings because the contact alloys are matched to iron and constantan.

Compatibility Checks

Verify that the sensor cable uses Type J wire and that the mating plug follows the same standard two-pin layout. Confirm the panel cut-out or mounting method matches the jack dimensions, and ensure the operating environment stays within the stated temperature ceiling.

Questions about this item

Which Dayton Type J thermocouple jack should I choose for a standard two-pin sensor?

The 36GL03 is a standard Type J jack with two pins, glass-filled thermoplastic housing and Constantan/Iron contacts, matching the common Type J sensor format.

What does the 428 °F / 220 °C rating mean when the jack is installed on my equipment?

It indicates the highest continuous temperature the jack body and contacts can withstand without degradation, so the connection remains reliable in typical Type J process environments.

Is this a standard Type J connector, and what does that limit in practice?

Yes, it uses the industry-standard Type J pin spacing and polarity, so it only accepts Type J thermocouple plugs and caps the circuit at the Type J temperature range.
