New Series 09 rugged CAN keypads For rugged applications in heavy duty and special vehicles
High reliability and functional safety are crucial to controlling safety-related applications in vehicles and machines – whether in construction equipment and vehicles, agricultural equipment or in special and commercial vehicles of various types. Harsh environments and low back panel depth require a robust and compact product design. The actuators and indicators must also be precisely configured, both mechanically and electronically, to suit the respective application. The new high-quality Rugged CAN Keypad and Rugged CAN Rotary Cursor Controller from Series 09 meet these requirements with cutting- edge system integration.
Typical applications • Roadmaking vehicles and roller compactors • Loaders, dozers and excavators • Cranes, dump trucks and crawler drills • Fire-fighting and rescue vehicles • Road sweepers, cleaning vehicles and refuse trucks • Snow removers and groomers • Agricultural vehicles and equipment
Robust, innovative design – Robust and innovative construction is a feature of the Rugged CAN Keypads design. The up to IP67 protected actuators and indicators work reliably at operating temperatures
from – 40°C to + 85°C. The low back panel depth and robust clip-in or screw-in mounting allows for easy, flexible installation, either vertically or horizontally. These high-quality devices also offer excellent tactile feedback, and are clearly visible in daylight and at night thanks to the powerful RGB LED halo and LED symbol illumination. Attractive and configurable 4-segment halo button illumination is integrated as standard. The customisable illumination provides the operator with excellent visual feedback, and is combined with a unique, contemporary design. Legends can be selected from our extensive library of industry-recognised, laser etched ISO 7000 symbols or customer supplied graphics to meet end user specific needs.

Is any memory card suitable for industrial applications?
Since their introduction in the 1990s, memory cards have remained among the most successful, trusted and low-cost storage solutions available. Consumer memory cards are cheap and commonly used to store images, videos, audio and text in portable devices such as cameras and smartphones. However, they are often also deployed for industrial applications that they are just not designed for.
Industrial-grade memory cards incorporate tough, reliable and high-quality components that can perform reliably over long periods of time to ensure maximum availability, minimal downtime and better return on investment. Industrial requirements are vastly different from personal or consumer use, being often not only mission critical but also safety and life critical. As more industrial systems become autonomous or require little to no human intervention, the efficiency of data storage and the timely access, delivery and analysis of information have never been more crucial.
Basing a decision on card capacity is a common mistake. For instance, believing that a “32GB card will be plenty of storage for our application”. SD cards have different modes, such as High Capacity (HD) and eXtended Capacity (XC), and may not work in every application, so it’s worth checking card compatibility from the outset.
Ideally, customers in the industrial sector should make purchasing decisions based on the total cost of a solution rather than immediate, short-term costs. Total cost of ownership may seem trivial for an SD or microSD card but when we factor in downtime of kit, engineering resource, logistics and human resource, not to mention customer dissatisfaction and any knock-on effects, it really is important to make the right decision from the design stage.
So, how do you choose the right storage solution for industrial applications? Key considerations include (but are not limited to) reliability, endurance, data integrity, capacity, speed and compatibility. It may sound confusing, but by understanding what the cards are being used for and how much data is being written to them, the right solution can be found. An additional advantage of industrial-grade cards is that they are highly customisable and can be tweaked specifically for your application, for example to prolong card lifespan or use less power.
3D NAND Flash impact Frequently, when we see cards failing it is because the wrong type of NAND flash within the card is being used. NAND flash comes in numerous grades, SLC, MLC, TLC, 3D etc. each with very different performance and endurance specifications, so it’s worth finding out how the NAND used could impact the card performance and ultimately the application and end user. Expert advice will help to ensure that the application works right first time.

Traffic Sign Control by
Energy Harvesting Switches When talking about Energy Harvesting Switches, the first applications that one thinks of are primarily in the smart home, building and industrial automation industry. A ZF Friedrichshafen AG’s customer, Westcotec, has developed an application for traffic signs using the ZF Energy Harvesting Switch.
Westcotec is producing a new traffic warning sign to help horse riders to cross busy rural roads. The riders have Energy Harvesting handheld transmitters and can switch the traffic signs on when approaching the road to warn car drivers of horses crossing. These switches work completely batteryfree and wireless. Only the mechanical actuation of the switch generates enough electrical energy to transmit an RF signal to the traffic sign and activate it. The lights then flash for 60 seconds and can be activated multiple times where groups of horses are crossing the road.
The same idea was implemented to herd animals across a road. When moving the animals the twin amber flashing beacons are triggered by the farmer with a push button on a hand held unit containing the energy harvesting switch.
