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.
