Misumi Adds Standard Precision Positioning Stages

Misumi has introduced a series of standard precision positioning stages to complement its existing line of high-precision positioning stages. The new stages feature a simplified product design that makes them suitable and cost effective for applications in which frequent and/or fine adjustment is needed but where ultra-high precision is not required.

The company's new standard precision stages are designed to deliver adjustment flexibility, with acceptable and repeatable precision levels in positioning devices for automated inspection, assembly and machining, as well as for processing instruments (such as welders) and production jigs. By streamlining functionality and precision levels (relative to straightness, pitching, yawing and rolling), Misumi can offer the new models at a price point 20-35 per cent lower than the pricing for its ultra-precise high-precision stages. The order fulfilment time is also shorter - the new series takes three days to ship versus six days for the high-precision models.

The series of standard precision positioning stages is comprised of three different versions and a total of 22 models. These include cross-roller stages (part number XCRS); available in nine different models - three sizes each in the x-axis, x-y-axis and z-axis versions - these cross-roller guides incorporate two rollers connecting upper and lower plate. The series also includes dovetail stages (rack and pinion, part number XDTS); available in nine different models - three sizes each in the x-axis, x-y-axis and z-axis versions - this slide mechanism consists of two precision-ground flat surfaces sliding against each other.

As a result of direct contact between the upper and lower aluminium-alloy plates, this stage is not suitable for high moment load. Also included are long-travel dovetail stages (rack and pinion, part number XDTLS); available in four different models - two sizes each in x-axis and z-axis versions - this slide mechanism extends the travel distance of the dovetail stage. All three versions have top and bottom surface plates made of aluminium alloy, with a black anodised surface treatment.

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.
