C&K Develops Industry’s First Fast Locking D-sub Connector System That Meets ESA Standards

C&K Components, a global manufacturer of pushbutton switches, tact switches, toggle and rocker switches, and smart card interconnect devices, has designed a D-sub connector that features a fast locking system for space applications. The highly reliable fast locking D-sub connector is the only device on the market that meets ESA qualification standards. 

The fast locking D-sub connector’s unique design provides blind assembly and eliminates the need for screws, washers, and clips during connector integration.   The cost-effective fast locking D-sub connector solution allows for maximum time savings during satellite assembly integration tests (AIT).

“Our new fast locking D-sub connectors deliver a safe, reliable solution for space application connector needs.  The practical design concept ensures there is no risk in losing pieces when working in harsh environment conditions,” said Gilles Parguey, product manager at C&K Components.

The D-sub connector can be used with the D*MA and D*M Series D-subminiature connectors in harsh environments. The fast locking system is ESCC QPL-qualified (under reference 3401-085) and can withstand excessively high vibration levels in equipment applications, such as connecting payloads and wiring harnesses.

Several versions are available, including male configurations (with or without back shells), female configurations, savers and hybrid options, with all variations guaranteed to meet the most stringent outgassing and residual magnetism requirements.

No tools are required to set the system, and five fast locking variants provide connection pairings for up to 36 sizes. The D-sub connector operates within a temperature range of -55ºC to +125ºC. A dedicated process identification document (PID) pilots all assembly and control operations, and the D-sub connector consistently meets ESA requalification every two years under the protocol set forth by the CNES (French Space National Agency).

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.
