ZF E-bike Speed Sensor Enriches the New Trend of ABS Applications

The ABS system has become indispensable in passenger and commercial vehicles. This safety function is also becoming increasingly popular for e-bikes. Bicycle accidents are often caused by uncontrolled braking, especially during emergency stops or braking on gravel and wet roads. The anti-lock braking system ensures a safe slowdown by evenly deaccelerating the front and rear wheels. To do this, the speed on both wheels must be measured constantly and precisely. The Hall-based speed sensor from ZF promotes this solution.

The ZF e-bike speed sensor GS82-AA02 was specially developed for use in Pedelecs and S-Pedelecs. Based on Hall technology, the sensor in combination with an external, ferromagnetic speed disk achieves a high-resolution speed measurement. The sensor targets the slot structure of the speed disc and, depending on the number of slots, it transmits up to 50 or more speed signals per wheel revolution. In practice, this leads to a finer and quicker response from the e-bike drive. The ABS system also benefits from the high resolution in speed. With the precise speed values of both wheels, the ABS control unit can adjust the wheels to each other and brake them in a controlled manner.

The extremely compact design (21.75mm long x 9.35mm in diameter) of the sensor fulfills the necessary requirements for the use in e-bikes. The speed sensor is based on the principle of the Hall effect and therefore it is contactless and wear-free. The differential measurement of the magnetic flux also increases the robustness of the sensor against vibrations. 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.

Characteristics
• Hall based non-contact and solid-state sensor
• Virtually unlimited life, no wear and tear from friction
• Immune to vibration, shock, dirt or water for an improved functional safety especially for Pedelecs, S-Pedelecs and E-Scooter
• Available standard product with Higo connector. Flexibility in terms of cable length and connector assemblies.
• High resolution in combination with speed and brake disk especially for slow speeds (e.g. hill starts)
• Hall sensor with speed disk for improved manipulation resistance and robustness
• Best suitable also for ABS-Systems

The Universal Digital Timer offers the same ease of use as analog timers but it is powered with visualization, higher-precision and all the functions you need (up to 138). The new Universal Digital Timer is well suited for a wide range of applications, ranging from heating and cooling in building equipment, Motor or pump control, industrial processes and lighting systems applications and many more.

SYR-LINE Universal Digital Timer‘s high-contrast led screen enables you to monitor the status of the timer. You can see the current time, the function and timing configurations, and know if you are receiving an input signal or if the relay output is activated.

With this Universal Digital Timer, its monitoring is made easy for you by adding

• Large, easy to read digits in 17.5mm for a clear and easy view of your timing status,
• Full scrolling words for best reading in such a slim body,
• Precise timing setting,

Large, manual dial to make configuration easy and intuitive using just your hands, even wearing gloves

Its wide time range, its universal mounting connection and the ability to accept universal voltage input gives the Universal Digital Timer a universal flexibility. It can indeed be programmed from 0.1 second to a 100-day delay and be used with any power supply available, since it works with voltages from 12 to 240V either DC or AC.  The Universal Digital Timer includes ALL the functions you need to run your applications, from the classics like on-delay «A» or off-delay «C», to special ones like repeat cycle «L». It also allows you to adapt them and get up to 138 real operating functions in one single product. This universal flexibility makes it the only ultra multi-function timer.

The new Universal Digital Timer has been built to be simple to use. You can program it in your hands without any power supply. You can get it ready in just a few seconds. Using the Basic parameters, you can configure your timer in only four steps and get it ready in just a few seconds. With the Advanced mode, you can configure all the optional additional parameters. Among those, the Universal Digital Timer offers two great features for you to set the limits. You can either limit user access by setting a password and defining user rights (full access, change time only, view only) or define time limit setting by allowing users to change time only between lower and upper limits.
