ZF Electronics CS100701 Hall Effect Gear Tooth Speed Sensor
The ZF Electronics CS100701 is a Hall Effect gear tooth speed sensor built for demanding industrial, automotive, and agricultural applications. Also known as the ZF Cherry GS100701, it detects the passing of ferrous gear teeth or rotating target wheels and converts that motion into a clean, reliable digital pulse signal — ready for your control system to act on immediately.
Moreover, it is available from OnlyPOS for just $62.99 — that is 41% off the RRP of $107.00 — making it one of the best-value genuine ZF Electronics sensors in Australia today.
Key Technical Specifications
- Operating Voltage: 5V to 24V DC — compatible with PLCs, microcontrollers, and embedded systems

- Target Compatibility: Ferrous metals (steel, iron) — including gear teeth, sprocket teeth, trigger wheels, and timing rotors
- Near Zero Speed Sensing: Accurate detection even at extremely low rotational speeds
- Body Style: Threaded barrel — mounts easily into standard sensor fittings and equipment brackets
- Brand: ZF Electronics (formerly Cherry Electrical / ZF Cherry)
- Part Number: CS100701 / GS100701
How It Works
The CS100701 uses a built-in Hall Effect element to detect changes in the magnetic field caused by passing ferrous gear teeth. Each tooth interrupts the field and triggers a digital pulse output. As a result, a controller or data acquisition system can count these pulses to accurately calculate rotational speed, position, or direction.
In contrast to variable reluctance (VR) sensors, Hall Effect sensors produce a clean square-wave output at any target speed. This makes the CS100701 ideal for low-speed and near-zero speed applications where VR sensors often produce weak or unusable signals.
Common Applications
- Industrial Automation: Motor shaft speed monitoring, conveyor belt control, and machine cycle counting
- Warehouse and Logistics: Forklift transmission speed sensing, AGV wheel speed detection, and conveyor feedback loops
- Automotive and Motorsport: Crank and cam signal sensing, ABS wheel speed detection, and gearbox output measurement
- Agricultural Machinery: PTO shaft speed monitoring, header drive sensing, and grain auger feedback
- General Industrial Equipment: Pump and fan speed monitoring, cooling system control, and any rotating machinery that requires a reliable digital speed signal
Hall Effect vs Variable Reluctance Sensors
Variable reluctance sensors are cost-effective, but their output amplitude drops at low speeds — sometimes too low for a controller to detect reliably. The CS100701, however, uses an active electronic output stage that produces a consistent pulse regardless of target speed. As a result, it is the right choice for applications that require reliable low-speed or near-zero speed detection.
NPN Output — Easy Integration
The CS100701 provides an NPN open-collector output, which is the most common type in industrial automation. Because of this, it works directly with Siemens, Allen-Bradley, Mitsubishi, Schneider, Omron, and many other PLC brands. In addition, it is compatible with Arduino, Raspberry Pi, and other microcontroller platforms.

Frequently Asked Questions
What is the ZF Electronics CS100701?
The CS100701 is a Hall Effect gear tooth speed sensor. It detects the movement of ferrous gear teeth or rotating target wheels and outputs a clean digital pulse signal. Consequently, engineers use it in industrial automation, automotive, agricultural, and manufacturing applications that require accurate speed measurement.
What is the operating voltage?
The CS100701 runs on 5V to 24V DC. Because of this wide voltage range, it is compatible with PLCs, microcontrollers, Arduino platforms, and standard 24V industrial equipment.
What type of output does it produce?
It provides an NPN open-collector sinking current output. This is the standard type for most industrial proximity and speed sensors, so it works with the digital input modules of most PLCs and control systems.
What can it detect?
The CS100701 detects ferrous metals — specifically steel and iron. For example, it works well with gear teeth, sprocket teeth, trigger wheels, and timing rotors.
Can it detect at very low speeds?
Yes. Because the Hall Effect design produces a consistent output independent of target speed, it works reliably at near-zero speeds. As a result, it suits applications such as pump monitoring, slow conveyor systems, and motor startup detection.
Is the CS100701 the same as the GS100701?
Yes — CS100701 and GS100701 refer to the same sensor. As ZF consolidated the Cherry Electrical brand, the product appeared under several naming conventions. You may also see it listed as the ZF Cherry GS100701 or Cherry Hall Effect Sensor.
What industries use this sensor?
The CS100701 suits a broad range of industries. In particular, it is common in manufacturing, industrial automation, warehousing and logistics, automotive and motorsport, agricultural machinery, and HVAC systems — essentially any application that needs a digital speed signal from a rotating ferrous target.
How is it installed?
The threaded barrel body mounts into a standard sensor bracket or tapped hole. Simply position the active face toward the gear teeth or target wheel with an appropriate air gap, then connect the power supply, ground, and NPN output signal wire. Contact our team on 1300 183 340 for detailed installation guidance.
What warranty is included?
The CS100701 from OnlyPOS comes with a manufacturer’s warranty that covers defects in materials and workmanship. For warranty details and claims, contact us at sales@onlypos.com.au or call 1300 183 340.
