Inmoco Expands Servotecnica Slip-Ring Range

Inmoco has introduced two robust Servotecnica commercial slip rings that offer the flexibility for up to 96 connections (216 upon demand). They also feature high voltage/current operation, low temperature working down to -40C and the ability to operate at speeds up to 800rpm. The new SRH 60135 and SRH 70155 series slip rings are designed for use in any system requiring the transmission of electrical and/or power signals to an intermittently or continuously rotating shaft.

This typically includes equipment such as video systems, robots and downhole inspection equipment, manufacturing and process control equipment, filling machines, medical equipment and packaging machines. Both series of SRH slip rings are available in many standard configurations; offer a high rating life of 10 (to the power of seven) revolutions (nominal speed 250rpm); and the facility of from six to 96 circuits, with up to 216 as an option. Their reduced size - the SRH 60135 is the smaller of the two - allows installation into compact systems, while a combination of low friction torque, high insulation resistance and a tough ABS housing guarantees high operating reliability and long life.

The design of the SRH series slip rings allows low peripheral-speed between brushes and rings, as well as reduced dynamic imbalance; the combination of these factors results in low wear. Noble metals and a new technology allow multiple contact points between bushes and ring, which reduces electrical noise and interference between circuits. All of these features make the SRH series suited to the transmission of critical signals, such as high-frequency signals (for example video and fieldbuses), low currents and voltages (strain gauges, thermocouples and measuring equipment).

Both SRH series are available for use with 600V AC/V DC voltages; they are IP51 protected (IP65 optional) against the ingress of dust and dripping water and offer an operating temperature range of -40C to +80C. The SRH series can be easily customised upon demand, in terms of connector types and cables, and also the number of circuits available from the SRH units.

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

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

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.
