Case Study Features

Critical, unique and extreme applications.

A UK leading designer and manufacturer of solenoids, switches, and a specialist provider of customised electro-mechanical assembly services, means we’re good at solving actuation challenges here at NSF Controls – especially for critical uses or unique and extreme applications.

Critical Applications

Dependable solenoid and switch solutions for critical uses

“NSF responded quickly to Mono’s request to solve a problem and provided a cost-effective component that has proved reliable for many years.”

- Mr D Thomas, Engineering Manager, Mono Equipment 

About the project

In this instance, the use of a traditional permanently latched solenoid conflicted with other magnetically controlled systems in use. As a result, NSF Controls developed the mechanically latched bi-directional tubular solenoid.

Versatile, lightweight and reliable with a lifespan of 10 million actuations in each direction, this component can typically be utilised by military, security and medical markets.

Unique Applications

Solving actuation problems for unique projects

“When I started developing the control system for this reproducing piano system, it soon became obvious that nobody’s standard solenoids would be good enough. To my surprise and delight NSF was willing to create almost anything I wanted, so we set to work on a design that suited my needs, yet was not awkward to manufacture. It was a joint effort and it absolutely achieves the design objectives.”

- Mr Richard Shepherd, R Shepherd Consulting

About the project

For this one-off project, a specialist tubular solenoid was created as part of the electro-mechanical system for a reproducing piano.

A set of 88 solenoids is used to actuate the piano keys, with fast repeats, subtle musical control and complete mechanical silence being crucial.

The Bösendorfer Imperial piano is shown photographed in The Great Hall, Castle Howard, North Yorkshire.

Extreme Applications

Answers for the most challenging environment

“Now that development is complete, NSF’s tubular solenoid is proving to be a reliable unit, satisfactorily meeting the demands of what is an extremely arduous and demanding application.”

- Mr Bob McCartney, Engineering Director, Macpactor Compaction Technology

About the project

For the global leaders in waste compaction technology, NSF Controls developed a tubular solenoid for longer strokes and high holding force applications. It produces a starting force in excess of 45 Newtons over a stroke of 30mm.

The holding force when closed is in excess of 90 Newtons. This powerful, heavy-duty solenoid can be sealed to prevent the ingress of dirt and moisture, making it suitable for tough environments.
