Encoder for temperature control for HVACs
Alps Electric
EC35A two-phase incremental-type encoder
Alps Electric has introduced EC35A, a low-profile, two-phase incremental-type encoder with 23.6mm hollow shaft, for easy setting of signal conditions in applications such as car navigation systems.
Other typical applications of the EC35A include volume control and function change for car AV equipment and menu selection for home appliances, such as washing machines and microwave ovens.
The vertically mountable SMT device has dimensions of 35 x 4.5mm and features a long 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 and operating temperature ranges from - 40C to +85C.
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 centre.
