Balluff Introduces Range of Ultrasonic Sensors

Balluff has introduced a range of ultrasonic sensors for applications such as object detection, distance measurement and sensing powdery and liquid media. The sensors do their job regardless of the colour, transparency or surface composition of the object, continuously and accurately. They can even operate in difficult light conditions, such as in dark, opaque or transparent areas; equally, reflecting objects are no challenge. According to the company, its ultrasonic sensors can also be used in dusty, humid and misty environments.

In addition, sensors featuring an IP 67 enclosure rating can replace multiple traditional sensors or provide additional distance information, since some versions in the cylindrical M30 housing feature an analogue output with two extra switching points. Ultrasonic sensors with M12 housings are not only ideal for detecting small parts, but also for the tightest mounting spaces. Their high resolution and minimal blind zone ensure high precision, according to Balluff.

At close range, they can detect virtually any material, even in critical environments, such as fog, steam, dust and dirt. With their stainless steel housings, these sensors can operate in harsh conditions, while the larger version in the M18 housing offers sensing ranges of up to 1,500mm. Some models can take over the function of multiple sensors. One or two switching points can be set on one ultrasonic sensor, an analogue measurement can be taken or one analogue output signal can be combined with two switching points.

Selected Balluff ultrasonic sensors can be synchronised, with the advantage that sensors that are located adjacent to each other do not exhibit mutual interference. For long ranges, there is also a maxi-sensor with optional switching or analogue output.

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.
