Grayhill 62F11-01-P-L Rotary Encoder Optical 32PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 62F11-01-P-L is an optical rotary encoder with 32 pulses per revolution (PPR) in quadrature (incremental) output configuration. This vertical-mounted encoder operates at 5V supply voltage and features a 1/4" diameter flatted end actuator with detent positioning. The part is Active status and ROHS3 compliant, making it suitable for industrial control, automation, and instrumentation applications requiring precise rotational feedback.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same functional category. Alternative models may be required due to inventory availability, series preference, or manufacturer sourcing constraints.

Substitute Part Grouping Explanation

Substitution eligibility for the 62F11-01-P-L is determined by strict equivalence in the following critical parameters:

Primary Substitution Criteria (Must Match):

• Encoder Type: Optical
• Output Type: Quadrature (Incremental)
• Pulses per Revolution: 32
• Voltage - Supply: 5V
• Actuator Type: 1/4" Dia Flatted End
• Detent: Yes
• Mounting Type: PCB, Through Hole
• Orientation: Vertical
• Termination Style: PC Pin
• Rotational Life: 1M cycles minimum

Identified Substitute Parts (32 PPR Configuration):

1. 62S11-M0-P (Grayhill Inc., Series 62S) – Maintains all primary substitution criteria. Differs only in series designation and termination connector style within the same manufacturer family.

2. HRPG-AD32#13R (Broadcom Limited, Series HRPG) – Cross-manufacturer substitute maintaining all primary substitution criteria. Represents alternative sourcing from different manufacturer with identical functional specifications.

Non-Equivalent Parts (Different PPR):

The following parts are listed in the substitute field but do not meet primary substitution criteria due to different pulse-per-revolution specification:

• 62F22-01-P-L (16 PPR) – Not equivalent; different resolution
• 62S22-M0-P (16 PPR) – Not equivalent; different resolution

These 16 PPR variants are suitable only for applications with different rotational resolution requirements.

Parameter Comparison

Engineering Selection Recommendations

Same-Manufacturer Substitution (Grayhill Series 62S):

The 62S11-M0-P represents an internal series variant within the Grayhill product family. Both the 62F and 62S series maintain identical electrical and mechanical specifications for the 32 PPR optical encoder configuration. Selection between 62F11-01-P-L and 62S11-M0-P depends on inventory availability and internal design documentation references. Both parts carry Active product status and ROHS3 compliance.

Cross-Manufacturer Substitution (Broadcom HRPG Series):

The HRPG-AD32#13R from Broadcom Limited provides functional equivalence with identical electrical performance and mechanical interface specifications. This option is suitable when Grayhill series components are unavailable or when design flexibility permits multi-source qualification. The Broadcom part maintains equivalent compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification).

Compliance and Regulatory Alignment:

All three equivalent parts share identical regulatory and compliance status:

• ROHS3 Compliant
• REACH Unaffected
• EAR99 ECCN classification
• MSL 1 (Unlimited moisture sensitivity level)
• HTSUS 8543.70.4500

Selection among equivalent parts does not introduce compliance risk or regulatory deviation.

Frequently Asked Questions (FAQ)

Q: Can the 62F22-01-P-L (16 PPR) be used as a substitute for the 62F11-01-P-L (32 PPR)?

A: No. The 62F22-01-P-L operates at 16 pulses per revolution, providing half the rotational resolution of the 62F11-01-P-L. This difference in PPR specification makes the parts functionally incompatible for applications requiring 32 PPR feedback. The 16 PPR variant is suitable only for applications with different resolution requirements.

Q: What is the difference between the Grayhill 62F and 62S series encoders?

A: Both series maintain identical electrical and mechanical specifications for equivalent PPR configurations. The series designation reflects internal product line organization within Grayhill's portfolio. The 62F11-01-P-L and 62S11-M0-P are functionally interchangeable for 32 PPR applications.

Q: Is the Broadcom HRPG-AD32#13R pin-compatible with the Grayhill 62F11-01-P-L?

A: Both parts feature PC Pin termination style and identical mechanical mounting specifications (PCB through-hole, vertical orientation, 1/4" flatted end actuator). Pin compatibility is confirmed by matching termination style and mounting type. Verify specific pinout documentation for signal assignment if required by application design.

Q: Are all three equivalent parts (62F11-01-P-L, 62S11-M0-P, HRPG-AD32#13R) suitable for the same PCB layout?

A: Yes. All three parts share identical mounting type (PCB through-hole), orientation (vertical), and termination style (PC pin). PCB footprint compatibility is confirmed. However, verify connector pinout assignments in application-specific documentation before final assembly.

Q: What compliance certifications apply to substitute parts?

A: All equivalent parts carry identical compliance status: ROHS3 Compliant, REACH Unaffected, and EAR99 ECCN classification. Moisture sensitivity level (MSL 1 – Unlimited) is consistent across all options. No compliance deviation occurs when substituting among the identified equivalent parts.

Q: Can I substitute a 32 PPR encoder with a 16 PPR encoder if I adjust firmware?

A: No. The PPR specification is a hardware characteristic determined by the optical encoder's physical design. Firmware adjustment cannot compensate for the fundamental difference in rotational resolution. Application firmware must be designed for the specific PPR value of the installed encoder.
