Grayhill 62R15-01-P Rotary Encoder Optical 24PPR: Equivalent & Substitute Parts

Part Overview

The Grayhill 62R15-01-P is an optical rotary encoder with 24 pulses per revolution (PPR), providing quadrature incremental output. This encoder features a 1/4" diameter flatted end actuator, detent mechanism, and vertical PCB through-hole mounting with PC pin termination. The part is Active status and ROHS3 compliant. Substitute parts are identified when inventory constraints, lead time requirements, or application-specific needs necessitate alternative encoder models from the same manufacturer that maintain compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 62R15-01-P are identified based on strict compatibility criteria. The primary substitution parameter is Pulses per Revolution (PPR), which differs between the main part and available substitutes. The 62R15-01-P operates at 24 PPR, while substitute parts 62S22-M0-P and 62F22-01-P-L operate at 16 PPR. These substitutes maintain identical specifications across all other critical parameters: optical encoder type, quadrature incremental output, 5V supply voltage, 1/4" flatted end actuator, detent mechanism, PCB through-hole vertical mounting, PC pin termination, 1M rotational life, and full compliance with ROHS3 and REACH standards.

Substitution is valid when application requirements permit operation at 16 PPR resolution instead of 24 PPR. The encoder type, output format, electrical supply, mechanical interface, and reliability characteristics remain unchanged across all listed parts.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 62R15-01-P and substitute parts 62S22-M0-P or 62F22-01-P-L is determined by resolution requirements and inventory availability. All three parts maintain Active product status and full compliance with ROHS3 and REACH standards, ensuring equivalent regulatory and environmental qualification.

The 62R15-01-P provides 24 PPR resolution. The 62S22-M0-P and 62F22-01-P-L provide 16 PPR resolution. This difference in pulse count represents the only functional distinction among the three encoders. All other electrical characteristics, mechanical interfaces, mounting configurations, and reliability specifications are identical.

Selection criteria:

• Use 62R15-01-P when 24 PPR resolution is required
• Use 62S22-M0-P or 62F22-01-P-L when 16 PPR resolution is acceptable and inventory or lead time considerations apply
• All parts are suitable for applications requiring 5V optical quadrature incremental encoding with detent, vertical PCB mounting, and 1M cycle rotational life

Frequently Asked Questions (FAQ)

Q: Can 62S22-M0-P or 62F22-01-P-L be used as direct replacements for 62R15-01-P?

A: Direct replacement is valid only if the application firmware or mechanical system can operate at 16 PPR instead of 24 PPR. The encoders are mechanically and electrically compatible, but the pulse count difference requires verification that lower resolution does not impact system performance.

Q: What is the difference between 62S22-M0-P and 62F22-01-P-L?

A: Both parts are 16 PPR optical encoders with identical electrical and mechanical specifications. They differ only in series designation (62S versus 62F). Both are functionally equivalent substitutes for applications requiring 16 PPR resolution.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 62R15-01-P, 62S22-M0-P, and 62F22-01-P-L are all ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: What is the supply voltage requirement for these encoders?

A: All three encoders require 5V supply voltage. No voltage adjustment or additional power conditioning is required when substituting between these parts.

Q: Do these encoders include a built-in switch?

A: No. None of the listed parts include a built-in switch. All three are rotary encoders with detent mechanism only.

Q: What mounting configuration do these encoders use?

A: All three encoders use PCB through-hole mounting with vertical orientation and PC pin termination. Mechanical mounting is identical across all parts.

Q: What is the rotational life specification?

A: All three encoders specify a minimum rotational life of 1 million cycles, providing equivalent durability and reliability.
