(Specification)Standard Specification for Miniature Thermocouple Connectors
Standard Specification for Miniature Thermocouple Connectors
ABSTRACT
This specification covers separable single-circuit miniature thermocouple connectors with two flat pins. Connectors covered by this specification must be rated for continuous use to at least 300 °F (150 °C), but they may optionally be rated higher. This specification does not cover multiple-circuit connectors, multi-pin connectors, standard size connectors, connectors intended primarily for panel mounting, or high-temperature connectors (for example, those designed for continuous use at temperatures significantly above approximately 500 °F (260 °C)). The connectors shall be rated based on their performance during contact resistance, thermal gradient, and insulation resistance tests.
SCOPE
1.1 This specification covers separable single-circuit miniature thermocouple connectors with two flat pins. Connectors covered by this specification must be rated for continuous use to at least 300°F (150°C), but they may optionally be rated higher.
1.2 This specification does not cover multiple-circuit connectors, multi-pin connectors, standard size connectors, or connectors intended primarily for panel mounting. High-temperature connectors (for example, those designed for continuous use at temperatures significantly above approximately 500°F (260°C)) are not intended to be covered by this specification.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 The plug and jack may be ordered separately but many of the connector characteristics (see Table 1) are qualified as a mated pair. The requirements in this standard are applicable for the connector pair supplied by the same manufacturer.
