Air & Liquid-Tight Self-Sealing Washers For Metric Thread Sizes

APM HEXSEAL announced the expansion of their SEELOC® self-sealing, high-pressure washer line of available stock sizes, which will include the range of Metric sizes from M3 to M6. According to APM Director of Sales, John Arnold, “Six new popular metric sizes have been added as the foundation to satisfy the increasing international demand for this industrial-grade sealing washer line. We are experiencing a surge of metric size requirements from OEM’s who are building marine, medical, military, instrumentation and a broad range of electrical and enclosure equipment throughout the world”. Arnold added that “within this size range, the washer O.D. is 12.7mm to 25.4mm, and maximum thru-hole sizes are 6.35mm to15.87mm are being offered. Additional sizes are contemplated, based on demand”.

The SEEELOC® washer platform is built with 300 series stainless steel -- a uniquely profiled and ribbed silicone rubber section is molded onto one side (facing down) creating a high-pressure seal to 100psi. SEELOCs are rated to IP66/68 for Type 4X & Type 6 enclosure protection, and are resistant to salt water, acids, weather, sunlight, ozone and a myriad of harsh, hostile conditions. They can easily handle temperatures from-160°F to +500°F.

The APM self-sealing fastener line has been sold for more than 50 years under the following trademarks: SEELBOLT®, SEELSKREW®, SEELNUT®, SEELRIVET® and SEELOC®. APM fasteners are sold by leading electronics and industrial distributors throughout the United States, Canada and worldwide.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
