KH-EC561V10T302 Incremental Rotary Encoder: A Reliable Choice for Precision Motion Control

2026-08-20 185

I. Product Overview

The KH-EC561V10T302 is a 56 mm, low-profile, slim rotary encoder launched by Kinghelm. The product uses an SMD package, is supplied in bag packaging, and has a gross weight of approximately 14.8 g per unit. As an incremental rotary encoder, the KH-EC561V10T302 generates pulse signals or position-change information through rotational movement. It is widely used in audio equipment, home appliances, industrial control systems, instrumentation, automotive electronics, and smart terminals.

II. Key Technical Specifications

The core specifications of the KH-EC561V10T302 are as follows:

  • Encoder type: Incremental

  • Number of detents / pulses: 30 / 15

  • Output type: Dual-phase output

  • Rated voltage: 5 V

  • Rated current: 10 mA

  • Mounting method: Through-hole

  • Operating temperature: -20°C to +80°C

  • Insulation resistance: ≥100 MΩ

The combination of 30 detents and 15 pulses means that the encoder can generate 15 pulse signals per rotation while providing 30 tactile positioning points. This detent design gives the operator a clear stepped or tactile feel during rotation, enabling precise adjustment.

The dual-phase output (Phase A and Phase B) can determine the direction of rotation through the phase difference between the two signals, typically 90 degrees, providing the control system with both speed and direction information.

III. Operating Principle

Incremental rotary encoders convert the timing and phase relationships generated by a rotating code wheel into information about increases or decreases in angular displacement. Taking a photoelectric incremental encoder as an example, its fundamental operating principle is based on optical grating interruption. As the code wheel rotates, the interaction between the grating and the photosensitive components generates alternating high- and low-level pulse signals.

Unlike absolute encoders, which measure absolute position, incremental encoders generate relative pulse signals during rotation to indicate the speed and direction of the rotating object. An incremental encoder can provide changes in position rather than absolute position. Therefore, the system generally requires a reference point or zeroing operation to determine the absolute position.

However, because of their simple structure and relatively low cost, incremental encoders are particularly suitable for applications that require basic position feedback and are sensitive to cost.

IV. Application Scenarios

Typical applications of the KH-EC561V10T302 include:

  1. Consumer Electronics:
    Used for volume control, menu navigation, parameter adjustment, and other human-machine interface functions in audio equipment. Incremental encoders are also widely used in devices such as computer mouse scroll wheels.

  2. Industrial Control:
    Used as an adjustment knob on control panels for functions such as speed setting and position control. Incremental encoders are commonly used for position control and motor speed feedback.

  3. Automotive Electronics:
    Suitable for in-vehicle entertainment system controls, air-conditioning adjustment, and other applications. Incremental encoders can also be used for position sensing in automotive windows, sunroofs, seats, and rear-view mirrors.

  4. Instrumentation:
    Used for parameter adjustment and data input in precision measurement equipment.
