Broadcom AS20 Series Magnetic Absolute Encoder 7V, Digital Signal, Axial Type, 4 mm Shaft

Broadcom AS20 Series Absolute Encoder, 4mm Shaft Diameter, 10 MHz Switching Frequency - AS20-M42M-S11

This absolute encoder provides precise angular position feedback using magnetic sensing and digital output, designed for industrial control and motion systems. It operates across a wide temperature range and interfaces with common fieldbus and synchronous serial systems, delivering reliable single-turn position data for devices requiring non-volatile positional information.

Features and Benefits:

• RS485 and SSI interfaces enable flexible communication options
  Digital output maintains EXACT position without homing
  Operates up to 115°C for high-temperature environments
  Supports rotational speeds up to 12,000 rpm for fast-moving shafts
  Magnetic sensing permits contactless measurement for long service life
  Accepts supply voltages up to 7 V for low-voltage installations

Applications

• Suitable for servo drives requiring absolute position feedback
  Ideal for conveyor systems with variable-speed operation
  Used with automated assembly equipment in high-temperature zones
  Can be used for motor feedback in Compact actuator designs
  Suitable for remote sensing where robust digital communication is needed
