Hirose Unveils Crimp Contacts For LED Displays

Hirose has launched the DF57 range of headers, sockets and crimp contacts for use with LED displays, touch panels, small motors, industrial robots, LED lighting modules and digital cameras. The connector occupies 18 or 23mm approximate board space for the two- and three-contact position respectively and the height profile is 1.4mm. Power performance is not compromised by the small size and a 2A current rating per contact is realised. Hirose's 'Swing Lock' offers a double-locking mechanism to ensure reliability During the mating operation, the receptacle is inserted into the header at a slight angle by offering the cable end in first.

This engages with the positive lock. The mating operation is then finished by 'swinging' the other end of the receptacle in to engage with the friction lock, which provides a tactile click sensation to confirm correct mating. It also prevents the receptacle from floating. The positive lock can withstand a minimum of 5N of cable pull force, ensuring that the socket can not be accidentally removed from the header. A small lever makes the unmating process very quick and easy. Durability is achieved with 30 mating cycles. Blade contacts are utilised to prevent damage against any cable wrenching forces.

These are positioned within a strengthened housing lance to increase the retention further. An effective contact mating length of 0.42mm ensures good electrical continuity. The termination contacts on the header are fully moulded into the insulator to eliminate any gaps to prevent solder wicking. This range is available in two and three positions, with a four-position currently in development. These can accept AWG 30-28 cable sizes.

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.
