The use of an M12 coupler connector at the connection head of a thermometer, rather than standard cable outlet, enables quick and safe connection. In the hygienic, food and pharmaceutical industries such a design can be being demanded ever more frequently.
Used, plant manufacturers prefer to rely on pre-assembled cables with fitted connectors, since this completely eliminates having to fix the single strands into the thermometer head. Enough time required for assembly and for disassembly during calibration or when replacing the instrument can thus be reduced considerably. Another advantage is that, in case of changing out any instrument, incorrect re-wiring could be avoided.
In general, additionally it is worth noting that, to guarantee the operational safety of plants and because of their maintenance and servicing, it really is imperative that equipment is easy to completely clean and that moisture protection reaches a maximum. These requirements apply for all process components, also beyond your process (in the ? Easily ?).
Note
WIKA has adapted the full-metal M12 coupler connector, familiar from the TR21 (TR21-A, TR21-B, TR21-C) product line, to the cable outlet for thermometers with connection head and thus enabled a straightforward and reliable reference to a 4-pin M12 connection cable. The high-quality sealing concept of this connector has also shown in the extreme requirements of autoclavable sensors. As well as the already established TR21 miniature resistance thermometers, which were designed for the high IP requirements of sanitary applications, WIKA now also offers thermometer products with connection heads ? Frightening , TR22 (TR22-A, TR22-B), TR25 ? with a hygienic M12 coupler connector for the hygienic, food and pharmaceutical industries.
