Magnetic Detect Switch For Telecoms And Enclosures

C and K Components is offering a magnetic detect switch designed specifically for use in telecommunications and enclosure applications. The miniature, surface-mount RS Series switches each feature a magnetic reed sensor with an omnipolar orientation, allowing them to be operated with either pole of the magnet. David Webber, director of product management for C and K Components, said: 'Magnetic switches are typically implemented in the cabinets of rack and panel systems, with access to the fan, server and daughter card via a door or latch.

'These magnetic detect switches are employed to sense when the cabinet doors are closed, which, in turn, signals the fan to begin operating. 'The RS Series magnetic detects are particularly suitable for telecom and enclosure applications because of their miniature size, lifespan to one million cycles and rugged design, which allows them to withstand cabinet door slams and misalignment,' he added. Along with telecommunications and enclosure applications, the RS Series detect switches are also being implemented in consumer electronics, computers, medical devices, factory automation and security equipment.

Available with top or side actuation, the normally open RS Series magnetic detects feature a contact rating of 5.0VA, with a maximum switching current of 0.35A and a maximum carrying current of 0.5A. The maximum contact resistance is 200mohm initial and the operating temperature ranges from -40C and +140C. The RoHS-compliant and -compatible detect switches are available with either gull-wing or J-lead terminations, are pick-and-place compatible and are available in tape and reel packaging.

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.
