Rugged Coded Switches for Military Applications

Elma Electronic is offering a rugged version of its type 07 line of coded switches for use in military/aerospace, portable medical, industrial automation, vision/imaging and mobile PC applications. The M07A is a gray coded switch that comes in 16 positions down to two. BCD or Hex versions are available upon request. Based on Elma's type 07 switch line, the rugged M07A has a robust stainless-steel 6mm tapped shaft (3mm versions optional).

It meets MIL-STD-810F for salt fog and humidity and MIL-STD-202G for shock and vibration. The M07A also features a high-strength reinforced plastic body and IP60 or IP68 front-panel sealing at the customer's request. It is offered in THT or reflow (upon request) versions and with an end-stop design or endlessly rotating. The M07A also allows various position and coding choices, shaft styles and lengths, as well as customisation options.

Utilising gold-plated contacts and a nickel-plated bushing, the long-life switch performs a minimum of 10,000 rotational cycles. A rotational cycle is specified as a complete rotation from position one to the last position, and back again. It has up to 4Ncm switching torque and the operating temperature range is -40C to +85C.

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

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

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.
