Molex’s Woodhead MAX-LOC Plus Shielded Cord Grip Assemblies

By News Release | January 27, 2014

Woodhead rugged assemblies provide EMI/RFI protection for high-powered switching and harsh-duty applications

011414-CAS-NP-Molex-Max-Loc-PlusMolex Incorporated’s Woodhead MAX-LOC Plus Shielded Cord-Grip Assemblies feature a nickel-plated aluminum housing and shielding ring for superior electromagnetic interference (EMI) and radio frequency interference (RFI) protection. The assemblies enable Original Equipment Manufacturers (OEMs) and end-users to connect high-power electrical currents directly to an application with an exterior mounting enclosure, simplifying the installation process for high-volume, cost-sensitive programs. The assemblies also meet IP67 and IP69K ratings, making them ideal for high-frequency switched-mode power supply (SMPS) applications in harsh environments, such as those found in the industrial automation, aerospace and defense, alternative energy, and commercial vehicle industries.

“Noise generated by electronic devices can be very disruptive, causing system failures on power lines and wireless connections that are in close proximity, especially in rugged conditions,” said Tony Quebbemann, product manager, Molex. “For instance, commercial vehicle OEMs were looking for a lower-cost shielding and sealing gland that would stand up to both on- and off-road demands. The MAX-LOC Plus more than meets their requirements.”

The MAX-LOC Plus assemblies unite in a single solution several distinct design features found in other Molex products, providing cost and labor savings over conventional industry-standard products. These include:

  • A unique grip body with an internal cutaway design to ensure a clean passage for pre-assembled harnesses and pre-crimped lugs, simplifying assembly and field serviceability
  • A tapered shielding ring, rather than usual finger contacts, for a robust and reliable connection that ensures low contact resistance and cable grounding
  • An internal wedge-shaped grommet that seals against liquids and dust while providing a cable retention that can withstand a pull force of 50 lbs. (222.4N)
  • Two external mounting holes that simplify the installation process by allowing a single installer, versus two installers, to make the connection directly to the OEM panel, enclosure, or vehicle body
  • A compression nut and stop ring to ensure the cable gland stays tight under high-vibration conditions
