Grayhill 62HS22-H9-P Rotary Encoder Optical 16PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 62HS22-H9-P is an optical rotary encoder with 16 pulses per revolution (PPR), providing quadrature (incremental) output for vertical mounting applications. This encoder features a concentric actuator with integrated detent and built-in switch functionality, designed for PCB through-hole installation with PC pin termination. The part is currently in active production status with 717 units in stock.

Substitute parts are identified when design requirements allow for alternative encoder configurations while maintaining core functional compatibility across electrical specifications, mechanical mounting, and output characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 62HS22-H9-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: Concentric
• Detent: Yes
• Built in Switch: Yes
• 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
• Manufacturer: Grayhill Inc.

Variable Parameter Allowing Substitution:

• Pulses per Revolution (PPR)

The 62HS22-H9-P operates at 16 PPR. Substitute parts may operate at alternative PPR values when all other electrical, mechanical, and compliance parameters remain identical. This allows for resolution flexibility in applications where encoder resolution can be adjusted through firmware or system configuration.

Parameter Comparison

Engineering Selection Recommendations

62H2222-H9-P (Primary Substitute): The 62H2222-H9-P is a direct functional equivalent to the 62HS22-H9-P, matching all electrical, mechanical, and compliance specifications including the 16 PPR resolution. Both parts are manufactured by Grayhill Inc., maintain identical supply voltage, mounting configuration, and termination style. Selection between these two parts is determined by availability and series designation. The 62H2222-H9-P currently has higher inventory availability (1430 units versus 717 units).

62H3030-H9-P (Alternative Substitute): The 62H3030-H9-P operates at 12 PPR instead of 16 PPR, representing a lower resolution configuration. All other parameters—encoder type, output type, supply voltage, actuator type, detent function, built-in switch, mounting type, orientation, termination style, rotational life, and compliance certifications—remain identical to the main part. This substitute is applicable only in applications where 12 PPR resolution is functionally acceptable or where system firmware supports resolution adjustment.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the 62H2222-H9-P be used as a direct replacement for the 62HS22-H9-P?

A: Yes. The 62H2222-H9-P matches all electrical specifications (5V supply, quadrature output), mechanical parameters (concentric actuator, detent, built-in switch, PCB through-hole mounting, vertical orientation, PC pin termination), and compliance certifications (ROHS3, REACH unaffected, MSL 1). Both parts operate at 16 PPR. The primary difference is the series designation (62H versus 62HS).

Q: Under what conditions can the 62H3030-H9-P substitute for the 62HS22-H9-P?

A: The 62H3030-H9-P can substitute only when the application permits operation at 12 PPR instead of 16 PPR. All other functional parameters are identical. Applications with adjustable firmware resolution or those requiring lower resolution encoding are candidates for this substitution. Applications with fixed 16 PPR requirements cannot use this part.

Q: Are there any packaging or storage differences between these parts?

A: All three parts are supplied in bulk packaging with identical moisture sensitivity level (MSL 1 - Unlimited), indicating no special storage or handling requirements beyond standard component storage practices.

Q: What is the rotational life specification for these encoders?

A: All three parts specify a minimum rotational life of 1 million cycles, ensuring equivalent mechanical durability across the substitution group.

Q: Do these encoders require different supply voltages?

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

Q: Are these parts suitable for high-moisture environments?

A: All three parts carry MSL 1 (Unlimited) rating, indicating they are not moisture-sensitive and do not require special moisture control during storage or handling.
