25-bit absolute encoder for linear and hollow through application

It employs Broadcom's patented reflective optical encoding theory. The AR35 series offers high accuracy with correction, which is unattainable by the magnetic encoder.

The encoders are designed for industrial applications with a high operating temperature range of -40°C to 115°C.

The AR35-L Linear series encoder is designed for linear scale applications with absolute mode of output, whereas AR35-T Series provides a maximum axial through-hole of 9.5mm for through shaft motor and axial cabling applications.

Key value proposition for hollow through and linear series

• Compact in size
• DFN package suitable for SMT production
• Enabling hollow through rotary and linear operation
• High temperature range -40 to 115°C
• Highly versatile encoder with various concurrent output
• Great flexibility with multiple time user programmable configuration
• East of installation with hassle free alignment process
• MSL 3.0
