Pixel-counting sensor

The PresencePLUSTM pixel-counting sensor consists of a 512 x 384 CMOS pixel array with a programmable microprocessor, controller, lens, lighting, mounting bracket, and cable, all for a sale price under $1,700. It captures a 256-level grayscale image, converts it to black and white pixels, and compares the pixel count to the user-programmed upper and lower threshold values to render a pass or fail judgement.

Magnetic floats

LS-Series liquid level sensors are floats that activate reed switches when the water level changes, and then provide an output signal. Since they need no external power source, the magnetically operated sensors can be remotely placed to isolate the reed switch mechanically and electrically >1,000V dc, away from fluids. They can be made from polypropylene for use in water and dilute acids, or from polyamide for use in oil, petrol, and brake fluid.

A 'hardware store' for engineers

I've talked before about the ways Design News editors keep up with product developments, such as visits to and from vendor companies. Another way we find out the latest and greatest products and technologies by attending his era of the World Wide Web, perhaps one tends to dismiss the importance of such events. I've heard attendees say they can't wait for a show in order to find out about new products--they need information, and components, right away. While this may be true in the quest to faster time-to-market, tradeshows can still uniquely serve the design engineering effort in fostering creative designs. For example, at the WESCON show last fall in San Jose, I noticed during a time of slack floor traffic, that the ability to step up to various vendor booths to actually see and touch real products affords insight that virtual catalogs may not--things such as mounting nuances, surface finish, sealing, and operating mechanisms.

But perhaps the "hardware store" effect of a show is even more important. Years ago, I remember one engineer's advice if you're stuck on a design--go to the local hardware store and wander the aisles for ideas that may prod your brain. The tradeshow can serve the same purpose and provide mental fodder for future product design.

Similarly, keeping an alert mind can key you into innovations. Once when asked to design a quick disconnect for a massive wire bundle that had to function under either longitudinal or lateral force, the design solution came to me on the way to lunch--when I spotted an eyeglass tissue dispenser on the plant wall.

You never know where an idea will turn up.

Dc/dc converter

The ExcaliburTM series of 5 to 100W isolated and non-isolated dc/dc converters feature open frame housings, with the ability to mount the converter either vertically or horizontally.

Pick of the Issue

Photoelectric control

The HPK Series photoelectric control is a self-contained thin amplifier, at 25 x 23 x 5 mm. Its symmetrical design allows it to be surface mounted in four directions, making it appropriate for electronic applications demanding high-speed, subminiature photoelectrics in flat package. Uses may include electronic components detection, mail sorting, and small parts handling. It is available as a through-scan pair (emitter/receiver) with a typical response time of 1 msec.

Proximity sensor

The Q10S proximity sensor features a corner-mounted LED display that is visible from any direction, and a recessed cable compartment for wall-flush mounting. The sensor measures 10.2 x 16 x 28 mm, so it is appropriate for applications in valve position sensing, clamp detection on robotic arms, and cam detection. In addition, the Q10S has a 2-mm sensing range with repeatability of less than 2% of rated operating distance.
