New Speed Sensor from Cherry Targets Harsh Environments

Cherry's new GS102301 gear tooth speed sensor is perfect for any application where rugged, dependable speed sensing is required. This digital output Hall Effect sensor is self-adjusting over a wide range of magnetic flux densities, eliminating the need to optimize the sensor position within a small magnetic flux operating range. This feature also compensates for target run out. The single hall plate design is immune to alignment issues, allowing unlimited mounting positions.

This addition to Cherry's family of near-zero speed sensors operates in temperatures ranging from -40 degrees C to 140 degrees C and meets IEC60529 IP68 standards for water immersion. The sensor also contains circuitry that protects it from EMI and ESD and is reverse battery protected. The device requires a minimum input of 3mA to function properly.

Only 2.80" long, in a straight, threaded housing, this sensor will fit into a standard M20 x 1.5 o-ring port and withstands a maximum installation torque of 15 ft lbs. The Viton o-ring comes pre-installed. The durable Stanyl® plastic housing, with its resistance to environmental extremes, makes it suitable for a wide range of speed sensing requirements in transmission, engine and braking applications. The device has been tested for environmental exposure per SAE J1455 Section 4.4.1, which includes immersion in engine and transmission oils.

Manufactured with an open collector output, the GS102301 requires a customer supplied pull-up resistor. Operating voltage is 5 to 30VDC at the nominal operating range. The GS102301 mates with the Packard Metri-Pack 150.2 sealed female connector assembly 3F.

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.
