Motion control applications typically require one or more position encoders. Several types are available and the engineer must first decide whether an incremental, absolute, or commutation encoder is most appropriate. After this decision has been made, other selection criteria include resolution and mechanical aspects, such as the mounting pattern and motor shaft size.

Two years ago at electronica, Ohmite launched their first ceramic heatsink and a prototype resistor using the same material, this year they will have a complete range to talk to customers about following this week’s acquisition of the electronic components business of Kanthal, a part of Sandvik Group.

Supplier of advanced semiconductor solutions, Renesas Electronics, has announced a new family of automotive-grade 100V, four amp half-bridge N-channel MOSFET drivers. The ISL784x4 family features three devices: the ISL78424 and ISL78444 with single tri-level PWM input for controlling both gate drivers, and the ISL78434, which has dual independent inputs that separately control the high-side and low-side drivers.

Electric vehicle power electronics manufacturer REO UK has released an infographic explaining the three key areas for improvement in EV components. The infographic is available to download for free from the REO UK website and aims to help electrical and design engineers choose high quality electrical components to improve the efficiency and effectiveness of their upcoming EV projects.

Having launched a new product almost every month since the last electronica, there will be plenty to see on the Ohmite/Arcol stand (Hall B6-101). Development by both companies has resulted in products designed for engineers by engineers.

Two multi-channel +/-10V and 0-20mA precision A/D converters that better enable implementation of programmable logic controller (PLC) and distributed control system (DCS) modules have been introduced by Analog Devices, (ADI).

They say that one man’s junk can be another man’s gold and, although one may think that the saying only applies to car boot sales, the maxim also illustrates the state of the industrial power resistor market. Here, Martin Nicholls, sales director at Cressall Resistors, offers advice to manufacturers and plant managers who need to replace old or obsolete electrical resistors.

There would seem to be a world of difference between the current generation of advanced electric sports cars and the heavy industries where Leicester basedelectrical resistor manufacturer,Cressall Resistors traditionally operates. However, the common denominator is alightweight 25kW water-cooled resistor, as Martin Nicholls of Cressall explains.

Stackpole is now stocking the most popular sizes and resistance values of its HVA Series. The HVA Series offers high voltage handling up to 8000V in a small package size. The RoHS compliant and halogen free HVA Series offers resistance values from 1M up to 1G in tolerances as low as 1% and in 200ppm TCR. The high voltage film achieves VCR of 20ppm/V or better.

Manufacturer of inductive components, Premo, has announced the LFAD-Series (Diabolo-shape) antennas, providing up to 50% reduction in length aiming to produce same H-field with a different L/D core relationship. Most of the LF antennas in the market have a length 70 to 80mm for standard range, 150 to 170mm for mid-range and 250 to 350mm for long-range (Alma-Core).
