Data link connector for extremely rugged environments

September 20, 2011 // By Julien Happich
Amphenol Industrial unveiled a ruggedized, high speed connector for use in extremely harsh environments. The Max-M1 has been designed to withstand high vibration, high temperature and extremely rugged environments and meets IEC 61076-2-101 and SAE J 2839 standards.

The new system is housed in an HDM 12 EX impact resistant metal shell and available as a 90° right angle connector or in a straight version. Both are available in 4- and 5-pin configurations with B, D and P polarity codes in line with IEC 61076-2-101 specifications and come as stand-alone connectors or cable assemblies with the option to over-mold the cable assembly. The connector can be terminated into 0.8 mm² (18 AWG) or 0.5 mm² (20 AWG) wires as defined by SAE J1128 and 0.75 mm² or 0.50mm² conductors as defined by ISO 6722. The new connection system can withstand temperatures ranging from -40°C up to 125°C, while maintaining a current rating of 4 A at 250 V (4-pin) and 60 V (5-pin). The IP67 and IP69K compliant Max-M12 is dust and waterproof and resistant to high pressure and high temperature wash downs. The dielectric withstanding of the Max-M12 is 1,000 V and it is rated for impulse voltage of 1,500 V. The connector's electrical insulation provides a resistance of over 20 megaohms, while providing a high temperature life of 1,000 hours at 125°C. The contacts are rated at less than or equal to 5 milliohms each with a maximum drop of 50 millivolts.
