Rotary Position Sensors for Agricultural Machinery

Variohm Eurosensor has launched BEI Duncan 8360 rotary position sensors for use in agricultural and construction machinery, medical equipment, industrial automation and process control. Typical uses include steering angle, crane boom angle, throttle range and traction control feedback. The sensors feature non-contact potentiometric technology with continuous rotation, electrical angles up to 360deg and dual-redundant analogue outputs in a compact and robust IP65-sealed package that includes a splined through-hole design for direct shaft mounting.

The 8360 will suit both harsh-environment and safety-critical angle measurement applications where high reliability, long life and durability are important design considerations. The sensor has an input voltage of 5VDC and as standard includes dual redundant 12-bit analogue outputs with a range of 0.2VDC to 4.75VDC and accuracy to +/-0.6 per cent. A choice of 24 electrical angle ranges are available in 15deg increments up to a full 360deg rotation. With an overall thickness of less than 16mm and a nominal footprint of around 85 x 105mm, the 8360 series sensor can be mounted in extremely space-restricted areas where the through-hole will directly interface with a 12-tooth splined shaft from 16mm to 20mm in diameter.

For straightforward installation, the sensor has four face-mount bush inserts and is supplied complete with a 200mm cable assembly with a six-pin AMP connector. The robust and durable angle sensor has high shock and vibration resilience, overvoltage, short-circuit and ESD protection and magnetic shielding. The nominal operational temperature range is from -30C to +85C with a an extended temperature option of -40C to +125C. Further options include non-standard electrical angles, non-standard output slope, PWM output, CANbus communication, multi-turn versions, IP67 sealing and special shaft interfacing.

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.
