Ultrasonic Sensors Have Sound-Absorbent Material

Datasensor has introduced US30 Ultrasonic Sensors with M30 housing to expand its measurement and detection product portfolio. All the models present radial acoustic emission and the versions can have the following features: configurable PNP/NPN NO/NC bipolar digital output; 0-10V analogue output; and 4-20mA analogue output. Models also feature a detection field of 100mm-1m or 200mm-2m.

The response time is fixed in the models with digital output (45ms for 1m models and 92ms for the 2m models) and is selectable in the models with analogue output (45ms or 105ms for 1m models and 92ms or 222ms for 2m models). Electrical connection can be carried out using standard M12 five-pole connector. The sensors can be configured using the Teach-In procedure, using the two push-buttons on the rear side of the sensor, or using the remote input present on the connector. Two signalling LEDS show the operating status. The temperature compensation function corrects the sound speed changes due to temperature variations and maintain the sensor precision in all situations, thus guaranteeing a minimum resolution of 0.5mm for the 1m models and 1mm for the 2m models.

These functions make the US30 ultrasonic sensors an alternative to other typical detection technologies in critical applications in presence of fog, dust or smoke. Datasensor claims that these sensors can contribute to improving the quality and productivity in industrial automation systems. The US30 ultrasonic sensors detect all objects independently from their sound-absorbent material, transparency and colour, making them the suitable for applications in sectors such as automotive, packaging, machine tool and material transformation processes.

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.
