Extremely compact and precise

The highly compact design is the defining feature of MEGATRON's MBA and MKA rotary encoders. Thanks to their various configurations, these Hall effect absolute encoders are ideal for applications where space is limited. The MBA has a solid shaft and an imperial thread, while the MKA kit encoder offers designers maximum flexibility.

The compact MBA magnetic absolute encoder has a housing diameter of just 12.7 mm, and shaft diameters are available in 3.175 mm, 6 mm, and 6.35 mm. The encoder can be easily installed in the application via a central thread and cap nut. Thanks to the MOLEX plug connection, the signal cable can easily be connected to the evaluation unit during installation or disconnected from the application during maintenance work.

The MKA absolute Hall effect encoder has a very similar design to the MBA, with the only difference being that the MKA is a kit encoder (bearingless). It consists of an encoder unit, a mounting ring, and an appropriate slip-on magnet for the shaft. Thanks to its modular design, engineers can integrate the rotary encoder optimally into their application. MEGATRON offers the MKA for shaft diameters ranging from 3 mm to 6.35 mm. The key technical data is the same as that of the MBA.

Both absolute encoders offer absolute, analogue (0–5 V) or pulse width modulation (PWM) output signals, and operate at an operating voltage of 5 VDC with a resolution of 12 bits. The update rate of the position value is 0.14 ms for analogue output. The MBA and MKA can be used in operating temperatures ranging from -40°C to +125°C and can withstand vibrations of up to 20 g (10 Hz to 2 kHz). The MBA features IP40 protection on the shaft side and is available with either sleeve or ball bearings.
