Angular Rate Sensor Targets Interface Applications

VTI Technologies has announced that it has started volume production of the CMR3000, which is claimed to be the smallest and lowest-power-consuming digital output three-axis angular rate sensor. The CMR3000 is designed for user interface and game applications. The company's product manager, Pekka Kostiainen, explained that the sensor's low current consumption, sensitivity and small size make it suitable for consumer electronics manufacturers.

Kostiainen said: 'Due to gaming requirements, the measurement range is +/- 2,000dps with selectable measurement bandwidths. 'In the case of cell phones, the wafer-level package enables the smallest size of 3.1 x 4.2 x 0.8mm3 with digital SPI and I2C interfaces, which is a clear benefit,' Kostiainen added. The CMR3000's small device size and location of the I/Os enable designers to optionally accommodate another manufacturer's sensor on the same layout.

This is said to offer a solution to high-volume customers with second-source requirements. To support easy implementation of the CMR3000 VTI is providing HW and SW support to customers. As an example, an Android driver is available including the library, documentation and demo applications. Furthermore, VTI supports customers with optimising sensor signal processing for their application.

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.
