Grayhill 62S22-M9-P Rotary Encoder Optical 16PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 62S22-M9-P is an optical rotary encoder with 16 pulses per revolution (PPR), delivering quadrature incremental output. This vertical-mounted encoder features a 1/4" diameter flatted end actuator, integrated detent mechanism, and built-in switch functionality. The device operates at 5V supply voltage and is designed for PCB through-hole mounting with PC pin termination.

The 62S22-M9-P maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified based on matching electrical specifications, mechanical compatibility, and operational parameters that permit direct functional replacement in applications where encoder resolution or specific series requirements allow substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 62S22-M9-P are identified based on strict parameter matching across the following critical criteria:

Mandatory Matching Parameters:

• Encoder Type: Optical
• Output Type: Quadrature (Incremental)
• Voltage - Supply: 5V
• Actuator Type: 1/4" Dia Flatted End
• Detent: Yes
• Built-in Switch: Yes
• Mounting Type: PCB, Through Hole
• Orientation: Vertical
• Termination Style: PC Pin
• Rotational Life: 1M cycles minimum
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Variable Parameters Permitting Substitution:

• Pulses per Revolution (PPR): Substitutes may differ if application design accommodates resolution variance
• Series Designation: Different series (62S vs. 62N) permitted when all other parameters align

The 62S22-M9-P has two identified substitutes: the 62S22-M5-P (same series, identical PPR) and the 62N30-P (different series, lower PPR resolution).

Parameter Comparison

Engineering Selection Recommendations

62S22-M5-P Selection Criteria:

The 62S22-M5-P is a direct functional equivalent to the 62S22-M9-P. Both encoders share identical electrical specifications, mechanical form factors, and operational parameters. The distinction between these parts lies in packaging or internal component variants (indicated by the M9 vs. M5 designator), not in performance characteristics. Selection between these two parts is determined by packaging availability, inventory status, or procurement requirements. Current inventory shows 1309 units of 62S22-M5-P available versus 657 units of 62S22-M9-P.

62N30-P Selection Criteria:

The 62N30-P represents a functional substitute with a resolution variance. This encoder operates at 12 PPR compared to the 16 PPR of the 62S22-M9-P. All other electrical, mechanical, and compliance parameters are identical. Selection of the 62N30-P is appropriate only when application firmware or mechanical design accommodates the lower resolution output. The 62N30-P is from the 62N series rather than the 62S series. Current inventory shows 755 units available.

Both substitute parts maintain Active product status, ROHS3 compliance, and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 62S22-M5-P directly replace the 62S22-M9-P without circuit modification?

A: Yes. The 62S22-M5-P and 62S22-M9-P are electrically and mechanically identical. Both deliver 16 PPR quadrature output at 5V supply with identical mounting, termination, and switch characteristics. No circuit modification is required.

Q: What is the key difference between the 62S22-M9-P and 62N30-P?

A: The primary difference is encoder resolution. The 62S22-M9-P provides 16 PPR output, while the 62N30-P provides 12 PPR output. All other parameters—supply voltage, mounting type, actuator geometry, detent mechanism, built-in switch, and compliance ratings—are identical. Selection of the 62N30-P requires confirmation that the application can operate with reduced resolution.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 62S22-M9-P, 62S22-M5-P, and 62N30-P are all ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the significance of the M9 and M5 designators in the part numbers?

A: The M9 and M5 designators indicate packaging or internal component variants within the 62S22 base product line. These variants do not affect electrical performance or mechanical compatibility. Both parts are functionally equivalent.

Q: Can the 62N30-P be used in applications requiring 16 PPR resolution?

A: No. The 62N30-P operates at 12 PPR, which is incompatible with applications requiring 16 PPR resolution. Use of this substitute is limited to applications where 12 PPR resolution meets functional requirements.

Q: What is the rotational life specification for all three encoders?

A: All three encoders—62S22-M9-P, 62S22-M5-P, and 62N30-P—are rated for a minimum of 1 million rotational cycles.

Q: Are there any differences in termination style between these parts?

A: No. All three encoders use PC pin termination for PCB through-hole mounting. Termination compatibility is identical across all substitute options.
