Keypads take on toughest conditions

Article Abstract:

Pemberton Dear has developed a hard-wearing sealed hydraulic control panel suitable for small batch production. The panel was originally designed to meet the environmental requirements of coal mine control units but it is sufficiently versatile for a variety of applications. Production and storage of half-finished panels enables a fast response to orders. Photographic tooling finishes the panel according to consumer requirements.

Hydraulic leaks stemmed at source: soft seal technology is playing a key role in the development of totally leak-free hydraulic systems

Article Abstract:

Hydraulic component manufacturers are taking steps to eliminate hydraulic leaks using soft seal dry hydraulic technology. Soft, elastomeric seals are tolerant of surface imperfections. There are new styles of soft sealed male stud couplings being produced which are often chosen as an alternative to the A and B styles.

Short circuit damps stepper oscillations

Article Abstract:

New approaches to stepper motor control have helped to cut costs in developing a new pen plotter. Traditional stepper motor control is based on current control, which offers poor results, and the new approach uses voltage control.
