Introduction to SICK SRM50-FPA0-K21 Encoder

SICK SRM50-FPA0-K21 belongs to the SRM50 series of small incremental rotary encoders, commonly used in equipment speed monitoring, position feedback, and motor control applications. This series is widely used in the field of industrial automation due to its compact structure, stable signal, and strong adaptability.

Key Features

compact structure
Designed with an outer diameter of 50 mm, suitable for installation environments with limited space.

Incremental output
Provide standard A/B/Z three channel pulses, suitable for control requirements such as direction recognition and reference point positioning.

High precision pulse resolution
Different ordering codes correspond to different PPRs. SRM50-FPA0-K21 is generally a medium to high resolution configuration, suitable for speed and position feedback.

sturdy and durable
Metal shell design, resistant to impact and vibration, suitable for ordinary industrial environments.

Flexible installation method
Adopting Synchro flange, installation and positioning are simple and reliable.

Multiple electrical interfaces are available
According to the K21 configuration, it is usually a push-pull output or differential output (depending on the nameplate), which is convenient for connecting to devices such as PLCs and drivers.
