HAND WHEELS TURN TO ALL APPLICATIONS
SAVINGS IN SPACE
When bdtronic developed a new concept for the successful B5090 mixing and dispensing machine, the aim was to create a more compact design, with space to be saved in the control cabinet too. Murrelektronik’s Emparro power supplies combined with MICO was an important contribution in this project

DS Component Parts has added new aluminium versions to its already wide
selection of hand wheels. Aluminium offers the advantages of light weight, strength and no corrosion, all attributes that can be useful in some hand wheel applications. Size for size, aluminium wheels are significantly lighter than cast iron or steel alternatives and often not much heavier than plastic ones. They are robust so can be used in applications where they may be knocked, hit or subject to other accidental mistreatment. Because aluminium does not rust, can be used in environments where corrosion may become an issue, as an alternative to stainless steel wheels, for example. The new hand wheels are available in spoked and solid versions and can be used for adjusting, setting or calibrating machines of all sorts. They can also be used on pipes, doors, medical equipment, precision machinery, or anywhere where a shaft needs to be turned manually. The new aluminium hand wheels complement
WDS’ existing offering of wheels that include plastic, metal, Bakelite, cast iron, glass fibre reinforced plastic (GRP), pressed steel and stainless steel choices. Both spoked and solid version are cast and polished aluminium and suitable for many possible duties. Eight diameter sizes are available, from 100mm to 500mm, and there is a choice of bore options that include H7 hole, keyway hole, pilot hole and square hole. Each hand wheel can be fitted with a fixed or rotating grip in several different styles. WDS offers a huge selection of fixed and rotating grips. These are available in a range of sizes, materials colours and designs so can be matched to the requirement of the individual application and helping make the overall installation as ergonomic as possible. For applications where fast rotation is required WDS can fit the hand wheels with revolving grips that allow the users to operate the wheel in a continuous fashion. WDS offers a range of shaft position indicators and control knobs. The shaft position indicators are available in vertical and horizontal orientations and provide up to five- position indication. Control knobs are typically chosen for applications such as machinery setting, and the WDS range includes graduated knobs, adjusting knobs and arrow buttons.

dtronic is located in Weikersheim in the south of Germany. The machine
building company has many years of experience in process and automation. Bdtronic’s machines and systems are used in many industries such as automotive, aerospace, and the electrical and electronics industry, as well as the filter industry, medical technology, and food and beverage. An important business area of bdtronic is developing and producing machines and process solutions for dispensing reactive resins and material preparation. These systems are built in a modular design and can be adapted to the users’ specific requirements. The fully automatic lean dispensing cell B5090 is an efficient system for processing components in batch production with liquid to paste-like reactive resins. A high level of automation ensures an
application of consistent quality and high productivity. In the course of reengineering, bdtronic’s designers aimed to find a more compact design for the machine. This was a challenge for the technicians from electrical engineering, because due to the machine’s smaller dimension, the control cabinet should also be smaller. However, the identical technical components have to be housed in this limited space. This meant that every single millimeter mattered. Therefore, the electronics engineers decided to use Murrelektronik’s Emparro power supply units. They supply the same amount of power as the units used before. However, with a width of 85mm (the 20A unit) or 65mm (the 10A unit) they are clearly smaller. Due to their high efficiency (up to 95 per cent, Emparro power supplies generate a very low heat loss. Therefore, not much safety distance is required. Bdtronic uses the intelligent VDC current
monitoring system MICO Basic to protect the cables. Four channels that used to be protected with individual circuit breakers are now monitored by an only 35mm wide cabinet component, and in the event of overload they are safely switched off in a channel-specific way. Signal contacts that require extra space when circuit breakers are plugged together are already integrated in MICO Basic. In the end there is a total saving in space on the
cabinet’s DIN rail of 85mm
(total width 185 instead of 270mm). Murrelektronik’s components made an
important contribution in reducing the amount of space required. There are also other positive ‘side effects’. For example, the integrated push in terminals require considerably less wiring efforts. Emparro’s high efficiency reduces the energy costs. MICO’s integrated LEDs make sure that the current load of the individual paths can be checked at a glance. This makes it possible to early counteract downtime.
