Connectors Feature Robust Locking Mechanism

Hirose has introduced the DF50 series of 1mm-pitch connectors for applications such as LCD displays, digital televisions, wireless LAN, industrial controller units, office equipment and more. Additional applications for the DF50 connectors include car navigation, car audio and amusement equipment. The DF50 range comprises single- and double-row compact receptacles and headers that have been designed with space savings and durability in mind for industrial applications requiring more strength and reliability.

The vertical housing and fine pitch of 1mm allow for maximum space savings on the board, reducing the mounting area needed. A metal lock provides a consistent and positive tactile click, even with repetitive mating. This ensures the connector is fully engaged, guaranteeing complete electrical and mechanical connection. The lock is centred on the housing to avoid uneven locking and cable entanglement, which is common with side locks. The housings have been designed with thicker and more robust walls to prevent cracking.

A long insertion depth and blade contacts are utilised to prevent damage against any wrenching forces. The receptacle features a robust and reliable lance structure, which keeps the contacts securely in place even when high forces are applied to the cable. High contact reliability is achieved with gold plating with a long effective mating length. Hirose said other benefits include surface-mount contacts and a vacuum pick-up area on the housing.

A nickel barrier is incorporated on the contact to avoid solder wicking. DF50 will be available in 20, 30, 40 and 50 contacts in double row. For single row, the number of contacts will be two to 16. The AWG 28 cable size is applicable.

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.
