The new M12-Mini bulkhead cable connectors with crimp connection technology from Provertha are a compact M12 solution and come with only 24.5mm length behind cabinet or housing wall (complete length 41 mm) for space-saving bulkhead solutions in control cabinets or housings.

At the same time, these versions are suitable for particularly high requirements in rail technology and industrial and factory automation such as presses for forming technology or stamping technology. They provide 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 available for the interfaces High-Speed 10 Gbit Ethernet with X-coding and for Ethernet with D coding as well as for Profibus with B coding and for CAN / DeviceNet interfaces with A-5 coding as female or male versions.

Nevertheless, the connector offers a large cable clamping range of four to nine millimetres. The special full metal housing ensures effective shielding with high EMC. At the same time, there is a solid, fully shielded strain relief. The new M12-Mini 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 through lateral flattened areas on the housing. The fastening thread is M16x1.5 and the locking is carried out with the counter nut included in the scope of delivery.

Thanks to the few individual parts, assembly is easy. The single wires (wire cross-section AWG 18 to 28) are connected using turned crimp snap-in contacts. For use 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 <5 mΩ. The degree of protection is IP67 (screw-locked). The M12-Mini can be used in the temperature range from -40 to + 85°C and enables more than 250 mating cycles.

Comprehensive M12 program from Provertha

Provertha M12 connectors are primarily characterized by reliable 360° shielded solutions like crimp flange/crimp sleeve cable termination and compact external dimensions. The M12 connectors are available in different codings, such as M12 A-Code, B-Code, D-Code and X-Code.

The circular connectors ensure reliable signal transmission even in extremely harsh industrial environments such as in railway or aerospace engineering. Optimized for the respective application, Provertha offers various solutions with extensive accessories, including M12 system cable assemblies.
