Gore Protective Vent Improves Reliability of Small Electronic Displays
W. L. Gore & Associates has expanded its line of adhesive vents with a product specifically engineered for small enclosures. With the smallest footprint in the Gore Protective Vent line, the VE80205 vent improves the integrity, reliability and safety of electronic components in harsh weather by equalizing pressure and reducing condensation. Despite the limited amount of free space and air volume inside small enclosures, sudden changes in environmental conditions can cause internal pressure to build up, sometimes as much as 200 mbar (3 psi). This level of pressure differential can put significant stress on seals, eventually causing them to fail. The VE80205 vent rapidly equalizes the internal pressure by allowing air to flow freely into and out of the enclosure. In addition, the breathable membrane that is incorporated into the vent reduces condensation by allowing moisture vapor to escape from the enclosure. At the same time, this membrane protects the electronics from liquids and particulates by providing a durable barrier that meets IEC’s IP67 standard. Available in standard packaging of five parts across a 41-millimeter wide carrier, the 2 mm by 5 mm VE80205 vent has a typical airflow of 103.62 ml/min/cm2 and is constructed with a robust adhesive that withstands challenging environments and adheres to different product surfaces. This construction enables the vent to be installed manually or with an automated process on either the internal or external wall of the enclosure without compromising its performance. with 15º tapered point for easy location of the mating hole when mounting faceplates in telecom rack system applications. Use of the specially styled pin and proper captive retention screw provide a faceplate mounting solution in accordance with Advanced TCA (Telecom Commuting Architecture) specifications and they satisfy the TCA PICMG 3.0 specification for 3 mm alignment pins. Pins are 16 mm long, made from 300 series stainless steel, and install permanently in aluminum or steel sheets as thin as 0.040 inches/1 mm.
Southco’s Multi-Point Swinghandle Provides a Solution for Indoor Industrial Enclosures
Southco’s H3 Swinghandle MultiPoint system is available in a lightweight, nylon version to reduce weight and cost when designing for indoor industrial enclosure applications. The H3 Swinghandle Multi-Point system is available with multiple offset cams, multi-point latching, locking and non-locking options. Constructed of glass-filled nylon, this lightweight latch provides durable performance with a flammable-resistant exterior in a compact profile. Independent specification of the latch body, cam, actuator plate assembly, extension rods and lockplugs allow for easy configuration of this system for single or multi-point latching, suiting most enclosure sizes and designs. Flexible locking options simplify access control security for indoor industrial enclosures. A built-in lock cylinder accepts standard Southco PK lockplugs and tool-access drivers. Lockplugs can be provided by Southco or by the end user while designers can choose to install either single, multiple or custom key codes.
PEM Release Self-Clinching Pilot Pins in Several Variations
PEM self-clinching pilot pins offered in several variations provide hardware solutions for positioning, alignment or pivot applications. All install reliably in thin metal sheets and become permanent parts of an assembly. PEM Type TPS (300 series stainless steel) pins install in steel or aluminum sheets and PEM Type TP4 (400 series stainless steel) pins are designed for stainless steel assemblies. Both types install flush in sheets as thin as 0.040 inches/1 mm or greater, feature a chamfered end to locate the mating hole quickly and easily, and are available in a variety of sizes and diameters. PEM Type MPP micro pins for compact electronic assemblies can be supplied with diameters as small as 0.040 inches/1 mm and in lengths as short as 0.080 inches/2 mm. They install permanently into stainless steel or other sheet materials as thin as 0.020 inches/0.5 mm and, upon installation, the pin’s head mounts flush with the host panel to promote a smooth and clean appearance for the assembly. The pins can be installed automatically to speed production and eliminate any need to handle the small parts. PEM Type TPXS self-clinching alignment pins are engineered
Heyco-Molded Break-Thru Plugs Serve Double Duty as Liguid Tight Plugs or Bushings
Heyco Products, Inc. has introducted its HEYCo-molded Liquid Tight Break-Thru plugs. Designed for use in panels as thin as 0.020 inches (0.5 mm) and as thick as 0.063 inches (1.6 mm) and mounting hole diameters of 0.500 inches (12.7 mm) to 1.093 inches (27.8 mm), these co-molded nylon and elastomer parts function as liquid tight plugs with an IP 67/68 rating, yet can be pierced by round wire, cable or tubing to function as Liquid Tight Bushings with the same resulting IP 67/68 rating. Used as a liquid tight bushing, HEYCo-molded Liquid Tight Break-Thru plugs insulate and mechanically protect electrical and telecommunications cable, tubing, hose, rope and utility lines. When pierced, they function as a liquid tight bushing that converts raw edged holes to smooth, neat, insulated holes. The plugs have locking fingers that snap into holes in fractional increments with simple fingertip pressure and withstand a push back force of greater than 35 pounds. Constructed of nylon 6/6 and TPE, the plugs are recognized under the Components Program of Underwriters Laboratories File E15331, Certified by Canadian Standards Association File 8919, have an HB flammability rating and operating temperature range of -40°F (-40°C) to 212°F (100°C).
