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

What shaft Interface does it accept?

It fits a 4 mm axial shaft connection.

Which signal formats are available for system integration?

It provides digital signalling via RS485 and SSI interfaces.

What is the maximum switching capability for control loops?

The encoder supports switching frequencies up to 10 MHz.

What environmental temperature range can it tolerate?

It functions between -40°C and 115°C.

Is there a restriction on rotational speed?

The unit is rated for operation at speeds up to 12,000 rpm.
