Panel Fasteners Conform To Machinery Directive

PEM panel fasteners designed specifically for tool-only access applications provide fixed screw solutions for a new EC machinery directive that imposes strict safety requirements for machine guarding. PEM's captive screws conform with Machinery Directive 2006/42/EC, which requires tool-only access fasteners to remain attached to fixed guards or machinery when the guards are removed. Effective from this year, loose screws are no longer acceptable in such assemblies.

These PEM panel fasteners with threaded captive screws have been engineered to install permanently into thin metal panels. Elimination of loose screws promotes quicker machine maintenance without the need to handle hardware and prevents screws from becoming lost either inside or outside a machine. The fasteners are UL-approved and installation is accomplished by placing the panel fastener in a prepared mounting hole and applying sufficient squeezing force using any type of parallel acting press.

Most types are flush on the backside of the panel for a clean appearance. Depending on type, available thread sizes range from 4-40 through 1Z4-20 and M3 through M6. The product line includes select types designed with a standard anti-cross-threading feature to protect from potential damage due to improper thread engagement. The fasteners can also be ordered with a Durablack finish to satisfy particular cosmetic requirements. Detailed specifications and free part drawings for these RoHS-compliant fasteners can be accessed on the Penn Engineering website.

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.
