Steelface Sensors Withstand Harsh Environments

Balluff has launched the Steelface range of sensors designed to survive longer in abusive applications such as metal processing in machine tools, in foods production, or in automobile technology. For error-proofing and part-present applications, inductive sensors are often - by necessity - placed directly in harm's way. Impact, abrasion, and particulate erosion can destroy conventional plastic-faced sensors, and replacing these damaged sensors is a costly and time-consuming process.

Balluff Steelface sensors are said to have an extra-rugged construction, reducing replacement costs and production downtime. Machining a single piece of solid stainless steel results in a sensor with a 1mm-thick, robust steel face that is impact-, chemical-, cutting fluid-, and abrasion-resistant. Available in M8, M12, M18 and M30 sizes (shielded and unshielded), Balluff said these sensors do not sacrifice sensing range for increased durability, achieving the same sensing range as the company's standard proximity sensors.

Additionally, a series of 2x or 3x extended sensing range allows the user to mount the sensor further away from the target, minimising the risk of impact damage. Special variants are available, such as PTFE-coated housings to repel weld spatter, and ferrous- or non-ferrous-selective electronics to sense a variety of different metals.

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.
