Miniature Thermocouple Connectors 400°F (200oC) Watlow's miniature connector is for both thermocouple and RTD circuits. This connector is suited for small wires or small diameter mineral insulated cables. The connector features a glass filled high quality thermoplastic body that makes for a more rugged and durable connector. Matching thermocouple alloys and spring loaded pin inserts ensure an accurate and strong signal. Captive terminal screws and molded polarity signals make for faster and easier wire termination with less error. Watlow's new miniature plugs and jacks will mate with previous...

Locking Miniature Connectors 400°F (200°C) The design of Watlow's locking miniature connector prevents the unwanted loss of signal that accompanies plug and jack separation. The bodies of the locking connectors are constructed of a high quality glass-filled thermoplastic that ensures a rugged design. Captive plate terminal screws allow for faster and easier wire termination. Both the plug and jack are marked for polarity to ensure proper assembly. Locking connectors are compatible with existing miniature thermocouples including Watlow's high temperature miniature connectors. All of Watlow's locking...

High Temperature Miniature Connectors 1000°F (540°C) Watlow's high temperature miniature connectors are constructed of a thermoset compound with a stainless steel bracket that results in a durable connector. The calibration of the connector is stamped onto the bracket, ensuring easy identification. Watlow's high temperature mini connectors are capable of withstanding intermittent temperatures as high as 1000°F (540°C) and continuous temperatures of 800°F (425°C). These connectors feature the same captive plate technology as Watlow's standard miniature connectors and are capable of accepting stranded...

Miniature Three Pin Connectors 400°F (200°C) Watlow's three pin miniature connector brings the same high quality characteristics as our standard miniature connectors while adding the ability to ground or shield a thermocouple connection or connect a three wire RTD. New captive plate technology as well as molded polarity symbols allow for a quick and painless wire connection. These connectors have the ability to accept wire sizes up to 24 AWG.
