New M12 bulkhead cable connectors with cable gland

29-07-2021 | Provertha | Connectors, Switches & EMECH

The new Provertha M12-Mini bulkhead cable connectors with crimp connection technology are one of the most compact M12 solutions in the industry and, with just 24.5mm length behind a cabinet or housing wall (complete length 41mm) provides space-saving bulkhead solutions in control cabinets or housings. At the same time, these versions are ideal for high demands in rail technology and industrial and factory automation, such as presses for forming technology or stamping technology. They offer certified shock and vibration protection according to DIN EN 61373, Cat. 2, and Cat 1 class B, and feature the 500h corrosion protection, proven by successfully passing the salt spray test according to EN 60512-11-6.


They are offered for the interfaces High-Speed 10Gbit Ethernet with X-coding and for Ethernet with D coding and Profibus with B coding and for CAN/DeviceNet interfaces with A-5 coding as female or male versions.


Nonetheless, the connector provides a large cable clamping range of 4mm to 9mm. The special full metal housing assures effective shielding with high EMC. At the same time, there is a solid, fully shielded strain relief. The new device ensures compact, safe and reliable data/signal transmission. The assembly on the control cabinet door or the housing wall is non-rotatable and with aligned coding via lateral flattened areas on the housing. The fastening thread is M16 x 1.5, and the locking is carried out with the counter nut included in the scope of delivery.


With the few individual parts, assembly is straightforward. The single wires (wire cross-section AWG18-28) are connected utilising turned crimp snap-in contacts. For employment in special applications, the turned crimp contacts have a higher current rating than the standard specification of 4A (2A for A-8) and the contact resistance of <5mOhm. The degree of protection is IP67 (screw-locked). It can be used in the temperature range from -40C to + 85C and enables more than 250 mating cycles.
