Miniature connectors
Miniature connectors
Where thermocouples are used for temperature measurement and/ or control, where the portability of measurement equipment is important, B+B Thermo-Technik Thermocouple Connectors are used. Possible measurement errors due to fluctuations in the ambient temperature are avoided, since all contacts are made of the corresponding thermocouple alloys. Thus no new thermo-electric forces arise at the contacts between thermocouple, extension cable and measurement device, which can distort the measuring values.
The thermocouple connectors are polarity-reversal safe and may be used -depending on the execution of the housing- up to 220°C. The contact pins are made exclusively out of solid thermocouples alloys, which insures also a high mechanical stability. Also available in high temperature plastic. The Miniature Thermocouple Connectors are suitable for cable diameters up to 0,5 mm².
B+B offers a comprehensive range of accessories for the connectors it supplies. From suitable strain reliefs to panel inserts, everything you need for assembling and installing connectors can be found under Connector Accessories. Crimping pliers are required to assemble the crimp sleeves as strain relief. B+B Thermo-Technik also offers matching compensation and thermal cables with different insulation materials for (ambient) temperatures up to 400 °C.
Thermocouple connectors are special electrical connectors that are used to connect thermocouples securely, precisely and without measurement errors to measuring devices, controllers or extension cables. The key difference to normal connectors is that the plug contacts are made of the same metal alloys as the respective thermocouple itself (e.g. type K: chromel/alumel) so that no additional thermoelectric voltage is generated at the plug connection, which would distort the measurement result. Thermocouple connectors are internationally standardised. The two most common standards are DIN EN60584 and ANSI. These standards specify the dimensions and alloys of the contact elements as well as colour coding, depending on the thermocouple type. There are two different designs: standard and miniature connectors. The standard design is robust and suitable for use in industrial plants. The miniature design is more compact and is more suitable for laboratory and test measurement applications.
Our thermocouple connectors can basically be divided into miniature connectors and standard connectors. There are also various couplings that are compatible with miniature or standard plugs.
