Grayhill Inc. 513360-9 Rotary Encoder Mechanical 9PPR Equivalent & Substitute Parts

Part Overview

The Grayhill Inc. 513360-9 is an active mechanical rotary encoder with 9 pulses per revolution (PPR) in BCD absolute output configuration. This vertical-orientation encoder features a 1/8" diameter flatted end actuator and is designed for panel and PCB through-hole mounting applications. The part is RoHS Compliant and REACH Unaffected, with unlimited moisture sensitivity rating (MSL 1). Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or application-specific requirements for alternative pulse-per-revolution specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 513360-9 is determined by strict parameter matching within the Grayhill Inc. Series 51 mechanical encoder family. The primary substitution criterion is compatibility across the following fixed parameters: encoder type (mechanical), output type (BCD absolute), actuator type (1/8" diameter flatted end), detent functionality (yes), mounting configuration (panel and PCB through-hole), orientation (vertical), and termination style (PC pin). The pulses per revolution (PPR) specification is the variable parameter that distinguishes substitute parts within this group. Substitute parts must maintain identical mechanical, electrical, and compliance characteristics while differing only in PPR rating. All substitute parts must retain active product status and equivalent regulatory compliance (RoHS and REACH).

Parameter Comparison

Engineering Selection Recommendations

The Grayhill Inc. 513374-8 (8PPR) is a valid substitute for the 513360-9 (9PPR) based on mechanical and electrical parameter equivalence within the Series 51 encoder family. Both parts maintain active product status and meet identical regulatory requirements: RoHS compliance, REACH unaffected status, and EAR99 export classification. The 513374-8 carries ROHS3 compliance, which is a higher standard than RoHS Compliant, ensuring continued regulatory alignment. Both encoders share identical mechanical construction, mounting interfaces, and operational characteristics. Selection between these parts depends solely on application requirements for pulse-per-revolution resolution. The 513360-9 provides 9PPR resolution, while the 513374-8 provides 8PPR resolution. Inventory availability shows 904 pieces of 513374-8 in stock compared to 667 pieces of 513360-9, which may influence supply chain decisions.

Frequently Asked Questions (FAQ)

Q: Can the 513374-8 (8PPR) directly replace the 513360-9 (9PPR) in my application?

A: Direct mechanical and electrical replacement is possible only if your application can function with 8 pulses per revolution instead of 9. The encoders are mechanically and electrically identical except for PPR specification. If your system firmware or hardware is calibrated for 9PPR, the 8PPR substitute will produce different resolution output.

Q: What are the key parameters that must match for substitution within the Series 51 family?

A: Substitution requires matching: encoder type (mechanical), output type (BCD absolute), actuator type (1/8" flatted end), detent function (yes), mounting type (panel/PCB through-hole), orientation (vertical), termination style (PC pin), and rotational life (25K cycles minimum). PPR is the only variable parameter among qualified substitutes.

Q: Are there compliance differences between the 513360-9 and 513374-8?

A: Both parts are RoHS compliant and REACH unaffected. The 513374-8 carries ROHS3 compliance, which represents a higher standard than the standard RoHS Compliant designation on the 513360-9. Both meet identical export classification (EAR99) and moisture sensitivity requirements (MSL 1).

Q: What is the difference in packaging between these parts?

A: The 513360-9 is packaged in standard format, while the 513374-8 is supplied in bulk packaging. Packaging differences do not affect mechanical or electrical compatibility; they relate only to order quantity and handling considerations.

Q: How do I determine if PPR differences will affect my circuit design?

A: PPR differences directly impact position resolution and output frequency. The 513360-9 provides 9 discrete positions per revolution, while the 513374-8 provides 8 discrete positions. Your application firmware or hardware must be capable of accepting the alternative PPR value. This is an application-specific determination based on your system requirements.
