Low-profile ring-type 2-phase incremental encoder with hollow shaft

March 14, 2011 // By Julien Happich
With the EC35A, Alps Electric Europe offers a low-profile 2-phase incremental-type encoder with a 23.6mm hollow shaft for easy setting of signal conditions. The vertically mountable SMT device measures 35x4.5mm (diameter x body height) and has an operating life of up to 50,000 rotational cycles. It provides a resolution of 15 pulses or rather 30 detents per rotation.

The necessary detent torque amounts to 18±7mNm. Rated for voltages of 5VDC, the EC35A has a maximum operating current of 10mA. The operating temperature ranges from –40°C to +85°C. The combination of an encoder with large hollow shaft and the reduced shaft wobble provide a comfortable operation and an accurate operation feeling.

In particular the encoder’s hollow shaft contributes to more freedom of set design as devices such as switches and LEDs can be mounted into its center. Typical applications of the EC35A are among others volume control and function change for car AV equipment and navigation systems, temperature control for HVACs, menu selection for home appliances such as washing machines and microwave ovens.
