Overview - find the right Hall effect sensor without guessing
Whether you’re building a brushless motor controller, a bicycle cadence sensor, or a student lab experiment, choosing a Hall effect sensor in South Africa means balancing sensitivity, package, and immediate availability. Communica stocks a wide range of magnetic and linear Hall effect sensors from maker-friendly modules to precision ICs so you can check price and pick up locally at our Samrand head office or Cape Town branch.
Why buy local stock now
Local availability reduces lead time and lets you verify fitment before assembly. Many projects require specific package types (through-hole for prototyping, SMD for production) or open-collector outputs for simple interfacing - we show those specs so you can compare quickly and avoid reorders.

Specification callouts to check
When comparing prices, ensure you compare the same spec: latching vs unipolar, digital vs analog output, operating voltage, sensitivity (mV/G or Gauss threshold), package and recommended air gap for magnet sensing. Below is a concise spec table to use when you compare options.
| Type | Output | Voltage | Sensitivity | Typical Use |
|---|---|---|---|---|
| Digital Unipolar | Open-collector / TTL | 3.3-24 V | ~30-100 G | Proximity switches, RPM |
| Linear (Analog) | mV/G analog | 3.3-5 V | 1-10 mV/G | Current sensing, position |
| Latching | Binary with polarity | 3-24 V | ± specific Gauss | Rotation detection |
Example compatibility check - avoid surprises
If your microcontroller runs 3.3 V logic, use a sensor with compatible output or add a level shifter. For simple RPM sensing on a bike hub, a digital unipolar sensor on a through-hole breakout often gives the best price-to-ease trade. For current sensing, a linear Hall with known sensitivity reduces calibration work.
