Product description: Hall effect multi-turn rotary encoder HSM22M

Thanks to the True-Power-On function, any angle changes are registered even during a supply voltage interruption and the angle is reproduced exactly as an analogue signal as soon as the supply voltage is restored.

The contactless sensor technology works on the basis of modern gradient-based magnetic field evaluation in processor-supported circuit design. This makes the multiturn encoder largely immune to external magnetic fields or changing ambient temperatures. In combination with the precision mechanics, the encoder shows its additional strength compared to magnetoresistive methods. The latter can have weaknesses in voltage-free measured value acquisition.

Another special feature of the multi-turn sensor are the signal plateaus at the beginning and end of the range, which prevent sudden signal changes. The electrically effective rotation range of the encoder is 3600°, ex works. On request, the HSM22M can be optimally adapted to the application by means of a factory-programmable electrically effective angle of rotation of 360° ≤ α ≤ 3600°. The encoder is available for operating voltages of 5 V/DC, 12 V/DC and 24 V/DC as well as with voltage and current output.

The redundant electronics contain a processor with two separate processor cores, which is supplied via two independent supply voltages and galvanically separated signal outputs (=6 conductors). On request, the redundant electronics can also be ordered with a common power supply and ground (=4 electrical connections). The electrical connection consists of individual strands with a length of 18 cm.

The encoder housing and precision mechanics are made of metal. For optimum protection of the electronics, they are mounted in a plastic carrier and fully encapsulated. The Ø6 mm shaft made of stainless steel has a flattened shaft. The sleeve bearing made of metal offers a lifespan of at least 20 million shaft revolutions. A permanent actuating speed of the shaft of up to 400 rpm is permissible.

The HSM22M is the first choice when optimum reliability is required. Typical applications are the precise position detection of cable winches and actuators. MEGATRON personalizes the HSM22M on request with a special shaft geometry, electrical connections as well as user-defined output signals.
