Incremental magnetic encoders with axis – Reliable measurement in difficult conditions
Precise determination of the position, direction and rotational speed of the shaft is the foundation for the proper operation of modern machine automation systems. The category axis incremental magnetic encoders includes advanced rotary-pulse encoders that combine the advantages of traditional pulse counting with the extreme mechanical resistance of magnetic technology. Unlike classic optical encoders, these devices do not have delicate glass discs, which eliminates the risk of sensor failure due to strong vibrations, shocks or sudden temperature changes.
Thanks to the high IP64 protection level and solid mechanical construction, the axis encoders available in this category are an ideal solution for direct coupling to the shafts of motors, gears and transporters working in a dusty and demanding industrial environment.
Configuration flexibility and unique benefits of the MEP series
The main challenge when selecting an incremental rotation sensor is the need to adjust the rigid resolution to the specificity of the application. Magnetic incremental encoders from the MEP40 and series available in WObit's permanent offer href="https://wobit.com.pl/produkty/1974/enkodery-mep50-obudowa-fi50-mm-os-fi8-mm-ip64/" target="_blank">MEP50 completely solve this problem.
Key technological differentiators:
Configurable resolution from 1 to 16384 imp/rev
Feature: The use of a modern magnetic system allows for factory programming of any number of pulses per revolution selected by the customer.
Benefit:As a result of this solution you receive a product exactly suited to the mechanics of your machine. You eliminate the need for software scaling of signals in the PLC, which shortens startup time and relieves the load on the central unit.
Two standard dimensions and axis diameters
Feature: The offer includes the compact series MEP40 with a housing diameter of 40 mm and an axis of 6 mmand a larger, reinforced series of MEP50 with a housing diameter of 50 mm and a rigid axis 8mm.
Benefit:Thanks to this procedure you can easily adjust the size of the encoder to the installation space of the device. Solid 6 mm and 8 mm shafts ensure high resistance to radial and axial loads.
Industrial signal transmission standard
Feature: Encoders generate pure square A, B, C signals with their full negations at a cut-off frequency of up to 800.
Benefit:In practice, this translates into perfect measurement smoothness without the risk of losing pulses by the counting systems, even when operating at a maximum rotational speed of up to 6000 rpm.
Comparison of parameters of available series of axis encoders
All magnetic encoders offered in this category have an integrated, high-quality shielded cable LIYCY 8x0.25, 1.5 m long, which guarantees perfect compatibility electromagnetic radiation (EMC) in the vicinity of inverters and motors.

Recommended use
Magnetic incremental encoders with an axis are universal components dedicated to system integrators, machine designers (OEM) and maintenance services:
Drive feedback: Accurate monitoring of the shaft speed of stepper, asynchronous and brushless BLDC motors.
Packaging machines and filling lines: Quick control of the position of conveyors, feeders and dispensers operating in a continuous cycle.
Positioning systems in industry: Work in internal transport devices, manipulators and medium-duty CNC machines.
Quick service and UR: Perfect as universal replacement encoders - the ability to order any resolution allows you to replace damaged sensors from other manufacturers without having to retool the machine's mechanics.
FAQ – The most important information when selecting an encoder with an axis
How to order an encoder with a non-standard number of pulses per revolution? Just select the appropriate series (MEP40 or MEP50), and provide the exact desired resolution value (e.g. 1024, 2048, 4000 or a unique number of pulses) in the configuration field when placing the order. The device is factory programmed by WObit engineers and delivered as a ready-made plug-and-play component.
What is the difference between Push-Pull electronics and Line Driver? Version Push-Pull (PP) operates in the standard supply voltage range of 12...24 VDC and is most often chosen for direct connection to the digital inputs of PLC controllers. Version Line Transmitter (N) powered by 5 VDC uses differential signals, which ensures the highest level of immunity to interference EMI over very long cable runs.
Do magnetic axis encoders require additional sealing? There is no such need in standard industrial conditions. The factory IP64 protection level guarantees full resistance of the body and shaft zone against the ingress of dust and accidental liquid splashes, which allows for safe and failure-free operation directly on production lines.
