High-Density Card Socket Saves PCB Space

Samtec has introduced a high-density socket featuring a bi-level mating design comprising two levels of contacts on a staggered 1mm centreline, which creates a card-effective 0.5mm pitch. The Edge Rate High Density Edge Card Socket (BEC5 Series) is available with up to 140 I/Os in a 1 x 1.27mm-grid PCB pad layout, with four rows of contacts. This system is suitable for high-speed applications benefiting from its rugged Edge Rate contacts, which are designed for superior impedance control and reduced broadside coupling with increased durability and cycle life.

The 0.5mm pitch high-density socket accepts standard 1.60mm' and 2.40mm-thick cards. Additional features include weld tabs, alignment pins and lead-free solder charge terminations for easy board processing. Tin-lead solder charges, as well as alternative platings and pin counts, are also available. In addition to the new BEC5 Series 0.5mm pitch high-density system, Samtec's full line of High Speed Edge Rate Edge Card Sockets includes 0.8mm (HSEC8 Series) pitch in surface-mount and edge-mount designs for parallel, perpendicular and planar-board mating as well as a right-angle dual-stacking design (DSEC Series).

Stamped contact design sockets are also available in 0.635mm (MEC6 Series), 1mm (MEC1 Series), 1,27mm (MECF Series) and 2mm (MEC2 Series) pitches for edge-mount, right-angle and vertical applications. Pricing on the BEC5 is approximately $0.10 per mated line.

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.
