Grayhill 62S18-M0-P Rotary Encoder Optical 20PPR: Equivalent & Substitute Parts

Part Overview

The Grayhill 62S18-M0-P is an optical rotary encoder with 20 pulses per revolution (PPR), providing quadrature incremental output. This encoder is designed for vertical PCB mounting with through-hole termination and includes mechanical detent functionality. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when the 62S18-M0-P reaches end-of-life status, experiences supply constraints, or when application requirements permit operation at alternative resolution levels while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 62S18-M0-P are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Manufacturer: Grayhill Inc.
• Encoder Type: Optical
• Output Type: Quadrature (Incremental)
• Voltage - Supply: 5V
• Actuator Type: 1/4" Dia Flatted End
• Detent: Yes
• Built in Switch: No
• Mounting Type: PCB, Through Hole
• Orientation: Vertical
• Termination Style: PC Pin
• Rotational Life (Cycles Min): 1M
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Variable Parameter:

• Pulses per Revolution: 16 (substitute parts) vs. 20 (main part)

The substitute parts 62S22-M0-P and 62F22-01-P-L maintain all mandatory electrical, mechanical, and environmental specifications. The primary difference is the resolution, specified as 16 PPR instead of 20 PPR. This variation is permissible when application firmware or system design accommodates alternative encoder resolutions within the quadrature incremental output framework.

Parameter Comparison

Engineering Selection Recommendations

All three parts—62S18-M0-P, 62S22-M0-P, and 62F22-01-P-L—maintain active production status with identical compliance certifications (RoHS3, REACH Unaffected). Selection between these parts depends on application-specific resolution requirements:

62S18-M0-P (Primary Selection): Use when 20 PPR resolution is specified in system design. Current inventory: 1067 units.

62S22-M0-P (Series 62S Alternative): Use when 16 PPR resolution is acceptable and part remains within the same 62S series family. Current inventory: 660 units.

62F22-01-P-L (Series 62F Alternative): Use when 16 PPR resolution is acceptable and cross-series substitution is permitted. Current inventory: 1152 units.

All substitute parts share identical electrical supply voltage (5V), mechanical mounting configuration (PCB through-hole, vertical orientation), actuator geometry (1/4" flatted end), and environmental ratings (MSL 1, unlimited moisture sensitivity). The decision between 62S22-M0-P and 62F22-01-P-L depends on design documentation requirements regarding series consistency.

Frequently Asked Questions (FAQ)

Q: Can 62S22-M0-P or 62F22-01-P-L be used as direct replacements for 62S18-M0-P?

A: Direct mechanical and electrical substitution is possible only if the application design accommodates 16 PPR resolution instead of 20 PPR. All other electrical, mechanical, and environmental parameters are identical. Firmware or signal processing logic must be verified to accept the alternative resolution.

Q: What is the primary difference between the substitute parts?

A: The 62S22-M0-P and 62F22-01-P-L differ only in series designation (62S vs. 62F). Both provide 16 PPR output. All other specifications are identical. Selection between them depends on design documentation requirements for series consistency.

Q: Are there any compliance or environmental differences between these parts?

A: No. All three parts carry identical RoHS3 compliance, REACH Unaffected status, MSL 1 rating, and 1M minimum rotational life specification.

Q: What supply voltage do these encoders require?

A: All three parts operate at 5V supply voltage. No voltage conversion or additional power conditioning is required for substitution.

Q: Can these encoders be mounted in orientations other than vertical?

A: The specified orientation for all three parts is vertical. Mounting in alternative orientations is outside the scope of these part specifications.

Q: What is the mechanical interface for the actuator?

A: All three parts feature a 1/4" diameter flatted end actuator, providing identical mechanical coupling to external shaft or knob assemblies.

Q: Do these encoders include integrated switches?

A: No. All three parts are specified without built-in switches. External switching logic must be implemented in the system design if required.
