Heason Offers Thomson Elektrak Pro Actuators

Thomson Elektrak Pro series push-rod style linear actuators, which meet the requirements for agriculture, construction, medical, plus H and V applications, are now available from Heason Technology. Characterised by its extreme durability, toughness and compactness, the DC motor-driven Electrak Pro is available in Acme lead-screw or ballscrew versions with a broad range of options for simple open loop load actuation or sophisticated closed loop control. The CE certified Electrak Pro series is supplied in choice of 12 or 24V DC input as standard or optional 36V DC, allowing flexibility for battery or DC power supply operation.

The actuator's maximum stroke length is 300mm with a dynamic load rating of 2,000N for the ballscrew version and 750N for the lead-screw option. The Electrak Pro offers no-load speeds to 50mm/s and a 25 per cent full load duty cycle. An attractive 'clam shell' cast-aluminium housing with a stainless-steel extension shaft and support tube combine for a smart design. The Electrak Pro is rated for IP66 operation with an optional IP67 version for liquid immersion protection. The housing and its integral electrical connector are fully gasket sealed and together with an operating temperature range of -40C to +85C, the actuator is well suited for use in hostile indoor and outdoor environments where washdown and spray is frequent.

The compact size of the actuator allows installation in restricted spaces with an unextended length of around 250mm for the lead-screw version. As standard, electronic limit switches are fitted for over-travel protection and a load holding brake is included for the ballscew version. Further standard options include an electronic load monitor that checks critical parameters and shuts down the actuator if they are exceeded. The front and rear clevis mounting is straightforward for installation and removal, and in the event of power failure, an integral manual override can be accessed with a 5mm Allen key for fast hand-operated position adjustment. To suit the widest range of applications, the Electrak Pro series is available with a number of options and accessories.

These include position feedback from a choice of optical encoder or a potentiometer that can also be used as a part of a signal follower option that allows the actuator to track position from a customer-provided analogue input. A programmable limit switch option is available to modify the usable stroke length via a hand-held pendant, which may be removed after set-up to prevent unauthorised changes. In addition, a PWM speed control option interfaces load monitoring system with a customer supplied PWM input for variable speed control.

The actuator can also be supplied in a protective black paint finish if required. As a Premier Partner distributor for Thomson, Heason Technology can also supply fully customised versions of the Electrak Pro, together with controls as complete system solutions.

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.
