Hollow Shaft Incremental Encoder

1、 Working principle

The hollow shaft incremental encoder converts the timing and phase relationship of its angle encoder through an internal photosensitive receiver, thereby obtaining an increase (positive direction) or decrease (negative direction) in the angular displacement of the angle encoder. It can convert rotational motion into periodic electrical signals, and then convert these electrical signals into counting pulses, using the number of pulses to represent the magnitude of displacement.

2、 Product Features

Hollow design: With a hollow axis for easy passage on the shaft, it is suitable for applications that require the transmission of signals, electricity, or liquids through the shaft.

High precision: capable of providing high-resolution position information to meet the needs of precision measurement.

Multi signal output: usually has two orthogonal output signals A and B, as well as a zero position signal (Z signal), which can be used to measure rotational speed, direction, and position.

Easy to install: small size, light weight, easy to install and use.

High reliability: Adopting advanced photoelectric detection technology and scanning system, it has high reliability and stability.

3、 Main parameters

Resolution: The number of position divisions per rotation cycle of the encoder, with higher resolution indicating more accurate position information.

Pulse count: The number of pulses generated during each encoder rotation cycle, directly related to the resolution.

Working voltage: The range of power supply voltage within which the encoder can operate normally.

Signal types: Common output signal types include TTL, HTL, Open Collector, etc.

Maximum pulse speed: The maximum number of pulses that the encoder can process per second.

4、 Application Fields

Hollow shaft incremental encoders are widely used in various applications that require precise measurement of rotational motion or linear position, such as robots, automated assembly systems, laser/flame/water cutting equipment, electronic assembly equipment, etc. It can help the system achieve precise motion control and positioning, improving the efficiency and accuracy of equipment operation.
