ALPS mass produces 'RDCC0 Series' magnetic rotary sensor

ALPS ELECTRIC EUROPE GmbH has developed the “RDCC0 Series” rotary sensor for angle detection in devices such as foot controllers (pedals). Mass production commenced in August 2013.
Foot controllers for products like sewing machines, musical instruments and amusement machines need to be able to accurately determine the angle of the pressed pedal.

In regard to position and angle detection, there is a demand for rotary sensors that are able to determine how much a mechanism moves with high precision and which possess high durability for ongoing use over a long period.

Many of the most commonly used rotary sensors are resistive sensors that perform detection through contact and their precision and durability can be improved only to a certain extent, limited by the effects of abrasion and noise caused by sliding. This means there is a growing need for rotary sensors capable of non-contact angle detection for use in equipment demanding long life and high precision.

ALPS has developed the RDCC0 Series non-contact magnetic rotary sensor and started mass-producing the sensor in August. Use of an ALPS-developed high-precision magnetic element enables accurate angle detection and linearity of ±2%. Furthermore, the non-contact design eliminates contact abrasion, contributing to a long operating life of 10 million cycles, compared to one million cycles for normal rotary sensors.

The RDCC0 Series also has screw holes and a connector terminal on the side, allowing it to be integrated into end products without a PCB. This helps to reduce the customer’s soldering workload and improve freedom in equipment design.
