Overview

The Woodhead MAX-LOC® Strain Relief Cord-Sealing Grip (SKU: 5537) is a 3/4" NPT 90° angle male fitting designed for secure cable management in industrial environments. This premium-grade component provides exceptional strain relief and environmental protection for cables with diameters between 11.10mm and 12.70mm (.437" to .500"). Engineered by Molex (Woodhead), a leader in industrial connectivity solutions, the 5537 model features a rugged nylon body that resists impact, corrosion, and extreme temperatures, ensuring long-term reliability in harsh conditions. Key specifications include a zinc-plated steel compression nut for durability and a neoprene O-ring (when used with the optional locknut) that delivers a liquid-tight seal meeting NEMA Type 6P standards. The 90° angle male configuration optimizes space utilization in tight installations, making it ideal for machinery enclosures, control cabinets, push-button stations, and general-purpose electrical systems. The integrated rubber grommet prevents moisture, dust, and contaminants from entering enclosures while significantly reducing cord pull-out forces, thereby extending cable lifespan by minimizing mechanical stress at the entry point. This MAX-LOC® series product is certified to UL File No. E76954 and CSA File No. LR32159, ensuring compliance with rigorous industry standards. The modular design allows for quick field adjustments and replacements using standard tools, reducing downtime during maintenance or reconfiguration. The grommet is color-coded (orange for this cable range) for easy identification, and the fitting accommodates a wide temperature range while resisting exposure to oils, solvents, and other chemicals. For applications requiring enhanced sealing, the optional O-ring and locknut upgrade (available separately) provide additional protection against submersion and high-pressure washdowns. The 5537 model is distributed by Gross Automation and is a cost-effective choice for OEMs, system integrators, and maintenance teams seeking a durable, high-performance solution for critical applications where failure is not an option.
