Grayhill 62R22-02-P Rotary Encoder Optical 16PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 62R22-02-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 62R22-02-P maintains Active product status with 956 units in current inventory. Substitute parts become necessary when addressing application-specific requirements such as resolution variation, series availability, or supply chain optimization while maintaining core functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 62R22-02-P are identified based on strict parameter alignment within the Grayhill optical rotary encoder product family. Substitution eligibility is determined by the following critical parameters:

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
• Compliance: ROHS3 Compliant, REACH Unaffected

Variable Parameter Allowing Substitution:

• Pulses per Revolution: Resolution variation permitted within the same functional category

The 62R22-02-P has two identified substitute parts: the 62S22-M5-P (16PPR, same resolution) and the 62N30-P (12PPR, lower resolution). Both substitutes maintain identical mechanical, electrical, and compliance specifications while differing only in encoder resolution or series designation.

Parameter Comparison

Engineering Selection Recommendations

62S22-M5-P Selection Criteria: The 62S22-M5-P is a direct functional equivalent to the 62R22-02-P, maintaining identical 16PPR resolution and all electrical and mechanical specifications. This substitute is appropriate when the 62S series is preferred for supply chain continuity or when higher inventory availability (1309 units) is advantageous. Both parts are Active status products with ROHS3 compliance and REACH unaffected designation.

62N30-P Selection Criteria: The 62N30-P operates at 12PPR resolution, providing lower encoder resolution than the 62R22-02-P. This substitute is applicable only in applications where 12PPR resolution satisfies functional requirements. All other parameters—voltage supply, actuator geometry, detent mechanism, built-in switch, mounting configuration, and compliance certifications—remain identical. The 62N30-P is suitable for applications requiring coarser angular position feedback or lower sampling frequency requirements.

Compliance and Regulatory Basis: All three parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence for industrial and commercial applications. Moisture sensitivity level 1 (unlimited) indicates no special storage or handling requirements for any substitute option.

Frequently Asked Questions (FAQ)

Q: Can the 62N30-P (12PPR) replace the 62R22-02-P (16PPR) in my application?

A: The 62N30-P is mechanically and electrically compatible with the 62R22-02-P. However, substitution is valid only if your application can function with 12 pulses per revolution instead of 16. The lower resolution reduces angular position feedback granularity. Verify that your firmware or control system can operate with this reduced resolution before implementation.

Q: What is the difference between the 62R22-02-P and 62S22-M5-P?

A: Both parts are 16PPR optical rotary encoders with identical electrical and mechanical specifications. The primary difference is series designation (62R versus 62S). The 62S22-M5-P has higher current inventory availability (1309 units versus 956 units). Both are Active status products with equivalent compliance certifications.

Q: Are all three parts suitable for PCB through-hole mounting?

A: Yes. All three parts—62R22-02-P, 62S22-M5-P, and 62N30-P—feature PCB through-hole mounting with PC pin termination. They are mechanically interchangeable in terms of board-level installation.

Q: Do these encoders require special handling or storage conditions?

A: No. All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard industrial storage conditions are appropriate.

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

A: All three substitute parts operate at 5V supply voltage. No voltage conversion or power supply modification is required when substituting between these parts.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial electronics applications.
