Key Parameters

Substitute Part Grouping Explanation

The AS33-M42M-B53 qualifies as a direct substitute for the AS33-M50M-B53 based on the following critical parameters that determine functional compatibility:

• Encoder Type: Both parts utilize magnetic encoding technology
• Output Type: Both implement BiSS-C digital communication protocol
• Voltage Supply Range: Both operate at 4.5V ~ 5.5V
• Actuator Type: Both use external magnet actuation (magnet not included)
• Mounting Configuration: Both support chassis mount and motor mounting applications
• Orientation: Both feature vertical orientation
• Termination Style: Both use connector-based termination
• RoHS Compliance: Both meet ROHS3 requirements

The primary distinction between these parts lies in their resolution specifications (50B versus 42B), which relates to the pulses per revolution capability. The AS33-M42M-B53 offers programmable pulses per revolution, providing design flexibility for applications requiring variable resolution settings.
