Lit-up Rotary Encoders Save Control Panel Cost

Cliff Electronics' LED-illuminated rotary encoders and customisable translucent control knobs are suitable for application in audio, broadcast, industrial control, medical and telecoms equipment. Rotary encoders are widely replacing conventional analogue potentiometers for audio, instrumentation and industrial control functions as they offer more accurate, repeatable setting. Cliff's rotary encoder range features LED-illuminated spindles to provide visible indication of panel position or function.

Standard LED colours available are blue, green and red, but Cliff Electronics is now manufacturing a wide range of customisable translucent control knobs in its UK factory, in addition to a choice of eight solid colours. The translucent control knobs are available to fit standard pot and encoder shafts, with custom-designed translucent knobs available on request. According to the company, provision of an LED-illuminated shaft provides integrated indication to simplify and reduce the cost of control panels by eliminating the need to fit a separate LED indicator.

The Cliff Electronics rotary encoder range provides an output of 24 pulse/24 clicks and features a 24mm shaft with 'flats' of 15/17.5/20/25/30mm available. Switch contacts are rated at 5VDC/0.5mA and the operating temperature range is -40 to +85C making them suitable for industrial control applications. Typical applications for the new Cliff Electronics range of rotary encoders include audio, broadcast, industrial control, medical and telecoms equipment and many types of portable devices. The rotary encoders and translucent control knobs are available direct from Cliff Electronics UK, Cliff Electronics in the US and a number of franchised distributors.

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.
