Stripped ends of thermocouple wire are simply inserted between the contact base and washer, then tightened with two terminal screws, there are no loose parts. Connectors do not need to be wrapped around terminal screws.
Watlow miniature connectors can accommodate wire sizes from 0.001 inch diameter up to 24 AWG, stranded. The connector is made with high impact strength, 400°F (200°C) rated, glass-filled thermoplastic. To maintain the highest measurement accuracy, matching thermocouple alloy materials are used throughout. The same fine features and high quality performance characteristics found in Watlow's standard connectors are found in the miniature connectors.
