DC5-24V 400 Pulses Incremental Photoelectric Rotary Encode

The Incremental Photoelectric Rotary Encode (rotary encoder) is an optical shaft encoder that gives 400 pulses for every full turn of its shaft and runs from a DC supply of 5 V to 24 V. Inside, a slotted disc turns between a light source and a photo sensor, so rotation is counted without contact or wear. It lets Arduino, PLC and motor-control projects measure speed, angle and position accurately.

Incremental Photoelectric Rotary Encode Specifications

• Type: incremental rotary encoder
• Sensing: photoelectric (optical), non-contact
• Resolution: 400 pulses per revolution (0.9° per pulse)
• Supply voltage: DC 5–24 V
• Output: a pulse train while the shaft turns; count the pulses to find angle, distance or speed

Incremental Photoelectric Rotary Encode Applications

• Measuring motor speed (RPM) and shaft angle
• Position feedback for DC motors, CNC axes and linear stages
• Length and distance measurement with a measuring wheel
• Manual hand-wheel input for machines and control panels
• Robotics, mechatronics and PLC training

What's in the Box

• 1 × 400-pulse incremental photoelectric rotary encoder

Tip: Check the wiring label supplied with the encoder before connecting it. If you power it from 12 V or 24 V, make sure the output signals stay within your board's input voltage (3.3 V on ESP32, 5 V on Arduino Uno); many encoders of this type have open-collector outputs that need pull-up resistors to the board's logic voltage. Read the pulses with interrupt pins so none are missed at high speed.
