Parameter Comparison

Engineering Selection Recommendations

Both the FS310 and FS210 are active products within the FlexSense® I optical encoder series. Selection between these parts is based on application-specific requirements rather than compliance or availability constraints, as both components satisfy identical electrical, mechanical, and regulatory specifications.

The FS310 (reflective optical encoder) and FS210 (transmissive optical encoder) differ in their optical sensing methodology. The choice between reflective and transmissive configurations depends on the specific mechanical design and codewheel implementation of the target application. Both components maintain equivalent supply voltage ranges, output characteristics, and surface mount configurations suitable for SMT assembly processes.

Both parts carry RoHS Compliant certification and REACH Unaffected status, ensuring regulatory compliance for applications subject to these standards. Moisture Sensitivity Level 4 (72 Hours) applies to both components, requiring appropriate handling and storage protocols during manufacturing and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the FS210 directly replace the FS310 in an existing circuit design?

A: The FS210 and FS310 share identical electrical specifications, supply voltage requirements, output types, and physical mounting characteristics. Direct substitution is possible from an electrical and mechanical standpoint. However, the optical sensing method differs between the two parts (reflective versus transmissive). Substitution feasibility depends on whether the application's codewheel and optical path configuration supports the alternative sensing method.

Q: What is the difference between the FS310 and FS210?

A: The FS310 is a reflective optical encoder, while the FS210 is a transmissive optical encoder. Both are programmable quadrature output devices within the FlexSense® I series. The optical sensing approach affects how the codewheel must be designed and positioned relative to the sensor. All other specifications, including supply voltage, output format, mounting type, and compliance certifications, are identical.

Q: Are both parts suitable for surface mount assembly?

A: Yes. Both the FS310 and FS210 feature Surface Mount (SMD/SMT) termination with SMT Tab configuration, enabling direct integration into automated pick-and-place assembly processes.

Q: What is the Moisture Sensitivity Level (MSL) for these encoders?

A: Both the FS310 and FS210 carry MSL 4 (72 Hours) classification. This indicates that the components must be stored in controlled humidity environments and have a maximum floor life of 72 hours after exposure to ambient conditions before reflow soldering.

Q: Are these parts RoHS compliant?

A: Yes. Both the FS310 and FS210 are RoHS Compliant and REACH Unaffected, meeting regulatory requirements for restricted substances in electrical and electronic equipment.

Q: What supply voltage range do these encoders require?

A: Both the FS310 and FS210 operate within a supply voltage range of 2.97V to 3.6V, suitable for low-voltage digital logic systems and battery-powered applications.

Q: Are these encoders programmable?

A: Yes. Both parts feature programmable pulses per revolution, allowing configuration of output resolution to match specific application requirements without requiring different hardware components.
