FAQs
The 527B is designed for surface mounting, enabling quick attachment to walls or panel surfaces. With its compact footprint (4.5 in by 4.5 in by 2 in) and a weight of 3.5 lb, installers can reduce wiring runs and hardware while maintaining a clean, accessible wiring scheme in control panels and equipment housings.
The 527B carries an IP66 ingress protection rating, offering dust-tight and water-tight performance in non-hazardous environments. It complies with NEC/CEC standards and is suitable for ordinary locations. This combination supports regulatory compliance, safer operation, and reliable performance in industrial automation installations.
Yes, the IP66 rating provides strong protection against dust and powerful water exposure, making it suitable for certain outdoor installations and washdown-adjacent areas. However, it is intended for ordinary/non-hazardous locations, so it should not be used in hazardous or explosive atmospheres without additional protection.
The enclosure dimensions are 4.5 inches in length and height, with a 2 inch width, and a 2 inch depth. It weighs 3.5 pounds. These measurements help with layout planning, cable routing, and ensuring clearance for mounting and access within compact control panels and equipment housings.
Brass construction offers corrosion resistance and long service life, reducing maintenance costs. For lifecycle planning, pair the IP66 protection with regular moisture and dust management in non-hazardous environments, inspect seals periodically, and ensure terminations remain accessible for routine inspections and wiring upgrades in evolving automation applications.
