Now in the third generation of family ownership E Preston Electrical continues to grow and build on traditional values.

“We work hard for our customers to get the best products at the best prices while providing exceptional customer service.  We always do what we say we will, even if that is just a call back,” says Mark Preston, MD.

This is a principle that was rooted in the business from its inception over 30 years ago by founder, and grandfather to the current directors, Ernest Preston.

Although there is still a great emphasis on these traditional values the company has embraced new technology in all of its business operations and now launches a new digital venture.  The new interactive e-shop is aimed at increasing accessibility to existing and new customers.

“We have access to the latest technology from our suppliers,” says Matthew Preston, sales director. “We want to make dealing with E Preston as easy as possible.  We will continue to visit new and existing customers, and speak to them on the telephone, but with eprestononline we can offer them access to our company whenever they want.”

Click AwayThe new eShop will allow customers to log in to their own portal to view orders, print off documents such as acknowledgements and invoices, and allows them to place repeat orders.  Data sheets and supplier catalogues will also be readily available.

The company believes it maintains its position as a traditional company – or more appropriately, a modern company with traditional values.

ZF’s GS82-AA02 Sensor Increases E-Bike Speed Sensor Portfolio


With the increasing popularity and growing trend of e-bikes, bicycle system suppliers have set goals to optimize power and performance of their drive systems. In order to support the driver in the best possible way, sensors are needed to deliver the required data and therefore adapt the engine’s power support. An essential component is the ZF e-bike sensor for measuring the current speed. The ZF e-bike sensor is based on Hall technology with significant advantages over conventional reed switches.

Especially for high-quality e-bikes, all components need to be functional, from the drive to the battery and cabling. This is also the case with the ZF e-bike sensor. Speed sensors of the GS series have been specially developed for use in Pedelecs and S-Pedelecs. The extremely compact design meets the necessary requirements for the use in e-bikes. The sensors are based on the principle of Hall-effect and therefore they are non-contact and durable. In combination with ferromagnetic target wheels, a high-resolution speed measurement with over 50 pulses per revolution can be implemented without any problems. In practice, this leads to a finer and quicker response from the e-bike drive – especially at lower speeds (e.g. when starting up a hill). The differential measurement of the magnetic flux also increases the robustness of the sensor against vibrations. In addition, there is no need for an external magnet, which is used with conventional reed switches. These are frail against even slight shifts on the spoke, which leads to functional failures and shut down of the drive unit.

The GS82-AA02 is the latest addition to the ZF e-bike sensor portfolio. This sensor is significantly more compact than its’ predecessor (21.75mm length, 9.35mm diameter) and optimized for use in e-bikes. As an interface to the drive system, the Higo connector has a cross-section of only 0.14mm² and due to its small size is prevalent in the e-bike industry. Depending on the customer’s requirements the contact via connector, as well as the cable length, can be preselected individually. The sensor requires a constant voltage supply of 6.5 – 20 VDC and measures frequencies between 1 and 2,500 Hz. They are designed for a temperature range from -25 ° C to + 85°C to fulfill the declaration of conformity in the e-bike industry.

The ZF sensor was originally developed for ABS applications. In addition to e-bikes, other target markets include e-scooters and various sports equipment for this small and efficient sensor.

Professional Internal Device Design
There is the approach just simply to use the best of the best. In high-end sectors, not only the exterior but also the internal design must meet high standards. The RC320 rear covers from SCHURTER are a welcome addition for professional internal device designs.

Bulgin PSE Switch with Cable

Installation-Ready Piezoelectric Switch (PSE) for Wet Rooms, Spa and Pool Facilities

• Designed for IP67 Applications
• High-Quality PUR cable (15 m) for Speedy and Safe Installation
• High Reliability and Long-Life Time
• RGB Ring Illumination

The use of switches in wet rooms, spa and pool facilities, requires not only the right choice of switch technology, but can often require unusually long cables. Schurter meets this requirement with the launch of the installation-ready piezoelectric switch PSE, an elegant highend solution.

The pre-assembled polyurethane cable of the new PSE with cable is potted, which offers maximum flexibility and the highest IP protection during installation. Waterproof from switch surface to electrical connection, the cable is 15 metres in length. The installation of the switch is simple by means of a nut.

Highest Resistance to Corrosion
The housings of the factory assembled piezoelectric PSE family are made of stainless steel 1.4462. This steel is characterised by its particularly high resistance to corrosion, which is essential in areas with high humidity. The PSE switches offer maximum reliability and a long service life (20 million actuations). Hermetically sealed housings make the PSE with cable predestined for use in particularly harsh and inhospitable applications.

Resistance to Chemicals and Solvents
Notably the PSE with cable is resistant to chlorinated liquids and common pool chemicals.

RGB Ring Illumination
The actuator has a ring illumination with a total of 7 possible display colours. The supply voltage has a range of between 5 – 28 VDC and maintains a constant brightness.

The new PSE with cable is extremely versatile. Originally developed for spa and pool builders, it is ideal for use in any sanitary application. Other applications include medical technology, food processing or similar industrial applications where the highest degree of robustness and reliability are required.
