Product details
Molex's 1731070175 sets new standards in D-Sub, D-Shaped Connectors - Housings performance, optimized for next-generation industrial automation systems. This ruggedized D-Sub solution combines high-speed data transmission with exceptional mechanical durability, specifically developed for Industry 4.0 smart factory implementations.Utilizing D-Sub, Combo form factor, the connector achieves 40% higher contact density than standard D-Subs while maintaining compatibility with existing backplane architectures.The Plug for Male Contacts interface configuration incorporates redundant contact points that provide fail-safe operation, maintaining connectivity even with 15% contact wear.Engineered with 21 (17 + 4 Coax or Power) positions, the design supports hybrid power/signal distribution capable of handling 20A aggregate current across power contacts.Advanced 2 row staggered contact arrangement reduces crosstalk by 18dB at 6GHz, critical for maintaining signal integrity in high-speed PLC communications.The 4 (DC, C) - 21WA4 dimensional profile incorporates keyed polarization features that prevent mis-mating while allowing blind mating in confined spaces.Special Signal and Coax or Power termination method employs cold-welded crimp technology that achieves gas-tight connections with pull-out forces exceeding 50N per contact.Designed for Free Hanging (In-Line) installation, the connector features integrated alignment pins that ensure 0.1mm positional accuracy during automated PCB assembly.The Housing/Shell (Unthreaded) incorporates conductive elastomer seals that maintain IP67 compliance even after 250 thermal cycles (-40 C to +105 C).Including Grounding Indents, the design implements patented contact wiping action that removes oxide buildup during mating, maintaining <5m contact resistance over 10,000 cycles.Selected Steel, Tin Plated provides exceptional ESD protection (<0.1 surface resistance) while preventing galvanic corrosion in mixed-metal environments.
