Hardware Gore PolyVent XL Improves Reliability of Large Outdoor Enclosures W. L. Gore & Associates has expanded its line of screw-in Gore Protective Vents with a vent engineered for large outdoor enclosures with a volume in excess of 200 liters. The Gore PolyVent XL improves the integrity, reliability and safety of these large housings in challenging environments. Changes in environmental temperatures cause the air inside of large-volume housings to expand and contract frequently, which can lead to failure of the housing seals and compromised internal electronics. Integrating the Gore PolyVent XL into the housing provides such a high airflow that internal pressure remains equalized, enabling the manufacturer to simplify its design and protect electronics without having to add stronger seals or additional bolts. Sudden changes in environmental conditions can cause pressure to build up inside the housing, sometimes even exceeding 200 mbar (3 psi). This level of internal pressure can put stress on seals and housing materials, which can cause them to fail, resulting in reliability and safety issues. Constructed from a breathable membrane, the Gore PolyVent XL equalizes the internal pressure by allowing air to flow freely into and out of the housing at a rate of 16 liters per minute at 12 mbar. At the same time, the Gore PolyVent XL prevents liquid ingress at a pressure of 0.3 bar for 60 seconds (equivalent to water immersion at three meters). The Gore PolyVent XL membrane protects the electronics from liquids and particulates by providing a durable barrier that meets the IP69K standard, which addresses protection from high-pressure, high temperature spray. Performing in temperatures between -40°C and 125°C, Gore’s vent protects against harsh weather conditions as indicated by its passing performance standards such as the UL 746C ultraviolet test. The vent also increases housing life because of its durable welded cap, enabling the vent to pass the hail impact test specified in the IEC 62108 standard for the solar industry. Hammond Manufacturing Adds 24 Variants to Range of Handles Hammond Manufacturing has added a further 24 variants to its range of handles, which are designed to complement enclosures, subracks, chassis, drawers and panels used in the electronic, networking, broadcasting and electrical markets. All styles of handle have modern lines that will enhance any enclosure or subrack to which they are fitted. The handles family consists of six main types: round steel bar, styled plastic and aluminum, plastic, square and oval aluminum, flexible vinyl carry and lift-up. The handles are available in a choice of finishes to complement or contrast with the equipment to which they are fitted. Depending on the material and style, they are available in chrome plate, black plasticized coating, natural anodized or black anodized. Many types are sized for use on the front of panels or subracks from 1U to 8U high. For mounting on the sides of enclosures, the heavy-duty lift-up designs are rated at up to 330 lbs per pair. Each family offers a particular combination of strength 24 and aesthetics, ensuring that designers can combine the load carrying and functional requirements of the handle with a pleasing overall appearance. Wago Wire Vertical Jumpers for DIN-Rail Terminal Blocks New jumpers provide horizontal and vertical potential commoning for Wago Corp’s Double-Deck TopJobs 2000 series and X-Coms MINI 2020 series DIN-rail terminal blocks. Users can vertically common both levels of a double-deck terminal block or multiply potential over several adjacent DIN-rail terminal blocks. This can extend the functionality of select terminal blocks to help streamline BOMs, stock and designs. The Vertical Jumper carries a 13.5 A/500 V rating. The Push-in Wire Jumpers feature a 9 A/800 V rating (AWG 18) and are offered in 60 mm, 110 mm and 250 mm lengths to meet varying requirements. Spanning from AWG 20-4, TopJob S DIN-rail terminal blocks serve a wide variety of application ranges. Southco Expands R4-EM Line with Sealed, Corrosion Resistant Versions Southco, Inc. has expanded its R4-EM Electronic Rotary Latch product class to include a version suitable for outdoor environments. With its corrosion-resistant plated steel and stainless steel construction and fully-sealed internal actuator, the R4-EM Outdoor provides reliable electronic locking that is resistant to moisture and dust. The embedded electronic control allows for integration with an external control system and flexible, concealed installation provides vandal-resistance and accommodates a variety of outdoor applications. With a high working load and ultimate load, the R4-EM Outdoor ensures reliable operation in demanding applications. Additionally, the R4-EM Outdoor accepts control inputs from any access control device and delivers optimal design flexibility in challenging environments. PEM Type PF50 and PF60 Captive Panel Screws Enable Easy Access to Components PEM type PF50 and PF60 selfclinching captive panel screws keep hardware parts count to a minimum by integrating a captive screw in a spring-loaded assembly to promote efficient handling and installation. Permanent mounting in thin metal assemblies eliminates any risks associated with loose hardware that could fall out get lost, or misplaced and potentially cause damage to internal components. These fastener solutions suit panels, covers, drawers, racks and other access points where secure attachment and subsequent access will be necessary. Their low-profile design minimizes protrusion on front panels to satisfy particular functional and cosmetic requirements.
