Rotary Position Sensors Added To ST350 Series

Sensor Systems has added a range of Hall-effect rotary position sensors to its ST350 series. The company said the sensors simplify customer use by providing the CANbus outputs needed for new-generation control systems. An operating range up to 360deg gives customers greater control and system accuracy by allowing them to select a range more closely suited to their application. Supply voltage up to 30VDC and the CANbus DS301/DS406 profiles up to 1Mbits/s improve compatibility with a variety of control systems.

Linearity of +/- 0.50deg with a resolution of about +/- 0.09deg provides customers with increased measurement precision. Thermal drift lower than 100ppm/C allows applications under adverse ambient conditions. Different connector choices (for example, AMP Superseal or Deutsch) satisfy customer connection requirements. The ST350 series sensors use solid-state Hall-effect technology, providing non-contact operation, enhancing service life and reducing wear-out mechanisms.

This series uses a magnetically based, Hall-effect IC to sense rotary movement of the actuator shaft over an operating range. The IC, together with conditioning and protection circuitry and a permanent magnet, is sealed in a rugged package rated IP67 or greater for durability in harsh environments. A dual-output version is available for redundancy and backup. The ST350 series can be used in a range of applications including marine, medical, cranes, aerial platforms, drilling machines, excavators, robotics and mobile equipment.

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.
