Incremental rotary encoder Encoder EB20193870 — two-phase A and B, 24 impulses per revolution

Encoder EB20193870 is an incremental rotary encoder providing two-phase quadrature outputs (A and B) with 24 impulses per revolution. It is designed for basic position and speed sensing in motion control and industrial automation applications where low-resolution incremental feedback is sufficient. The device produces phase-shifted pulse signals that allow counting of angular displacement and detection of rotation direction when used with standard encoder interfaces or counters.

Advantages

The encoder delivers a simple and reliable two-channel quadrature output suitable for straightforward integration into control systems. With 24 pulses per revolution, it offers clear, low-resolution feedback that reduces processing requirements for controllers and counters. Its incremental output simplifies wiring and replacement in existing systems that expect A/B phase signals. The encoder's compact design and mechanical compatibility with common shafts make it practical for compact machines and retrofit projects.

Suitable for

• Basic position sensing in conveyor and material handling equipment
• Speed monitoring for motors and rotational assemblies with low resolution needs
• Motion control feedback in simple automation systems and PLC inputs
• Retrofit or replacement in legacy equipment that uses two-phase A/B incremental encoders
• Counting rotations where coarse angular resolution is acceptable

Key specifications

• Output type: incremental quadrature, two channels (A and B)
• Resolution: 24 impulses per revolution
• Signal format: phase-shifted pulse outputs for direction detection
• Mounting: shaft-coupled rotary encoder suitable for compact installations
• Use case: position and speed sensing in motion control and automation

How to use

Mount the encoder on the driven shaft or couple it using the appropriate coupling compatible with the encoder shaft diameter. Connect the two-phase A and B outputs to the counting or controller inputs designed to accept incremental quadrature signals, and provide the required power and reference ground according to the system's electrical specifications. Use a debounce or input filtering if the receiving electronics recommend it for noisy environments. Calibrate the system by counting pulses over a known angular displacement to confirm correct pulse polarity and direction detection.

Usage recommendations

For reliable operation, install the encoder away from strong electromagnetic interference and secure the cable to prevent mechanical stress at the connector. When precise angular resolution is required, consider signal interpolation or a higher-resolution encoder; for basic counting and direction detection, this encoder delivers adequate performance with minimal integration effort.
