Grayhill 26GS22-01-1-16S-F Rotary Encoder Mechanical 16PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 26GS22-01-1-16S-F is an active mechanical rotary encoder with 16 pulses per revolution (PPR) output in Gray Code (Absolute) format. This vertical-mounted encoder features a 1/8" diameter flatted end actuator, detent mechanism, and PC pin termination suitable for panel and PCB through-hole mounting applications. The component is RoHS compliant and REACH unaffected, with a rotational life rating of 25,000 cycles minimum. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part number becomes unavailable or when alternative termination styles are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 26GS22-01-1-16S-F is determined by the following critical parameters: encoder type (mechanical), output type (Gray Code Absolute), pulses per revolution (16 PPR), actuator type (1/8" diameter flatted end), detent presence, mounting type (panel and PCB through-hole), vertical orientation, and termination style (PC pin). All substitute parts must maintain identical specifications across these parameters to ensure functional and mechanical compatibility.

The substitute parts are grouped into two categories:

Category 1: Direct Equivalents (Identical Specifications) Parts that match all critical parameters including 16 PPR output. These parts differ only in termination connector style or internal construction while maintaining identical electrical and mechanical interfaces.

Category 2: Functional Alternatives (Different PPR) Parts that share the same mechanical form factor, mounting type, orientation, and termination style but operate at different pulse-per-revolution ratings. These parts are suitable only when system design permits alternative resolution specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Identical 16 PPR Operation):

The 26GS22-01-1-16S-C and 26GSD22-01-1-AJS are direct functional equivalents to the 26GS22-01-1-16S-F. Both parts maintain identical electrical output specifications (16 PPR Gray Code Absolute), mechanical form factor, mounting configuration, and compliance certifications. Selection between these parts depends on connector availability and internal construction differences. All three parts carry active product status and full RoHS compliance.

For Alternative Resolution Applications (8 PPR Operation):

The 26GSD45-01-1-AJS operates at 8 PPR instead of 16 PPR. This part is suitable only for applications where lower encoder resolution is acceptable or required. The mechanical interface, mounting type, orientation, and termination style remain identical to the primary part. This substitution requires system-level design review to confirm that 8 PPR output resolution meets application requirements.

Compliance and Certification:

All substitute parts maintain identical RoHS compliance status, REACH unaffected designation, and moisture sensitivity level (MSL 1 - Unlimited). No additional qualification or testing is required from a regulatory standpoint when substituting between these parts within their respective PPR categories.

Frequently Asked Questions (FAQ)

Q: Can the 26GS22-01-1-16S-C be used as a direct replacement for the 26GS22-01-1-16S-F?

A: Yes. Both parts are mechanical rotary encoders with identical 16 PPR Gray Code Absolute output, 1/8" flatted end actuator, detent mechanism, vertical orientation, and PC pin termination. The parts differ only in internal connector construction. Electrical and mechanical compatibility is complete.

Q: What is the difference between the 26GSD22-01-1-AJS and the 26GS22-01-1-16S-F?

A: Both parts share identical specifications including 16 PPR output, mechanical encoder type, Gray Code Absolute format, actuator type, detent, mounting type, orientation, and termination style. The difference lies in the base product series designation (26GSD22 versus 26GS22), which reflects internal design variations. Functional compatibility is maintained.

Q: Can the 26GSD45-01-1-AJS replace the 26GS22-01-1-16S-F in any application?

A: The 26GSD45-01-1-AJS operates at 8 PPR, half the resolution of the 26GS22-01-1-16S-F (16 PPR). Mechanical and mounting compatibility is identical, but electrical output differs. This part is suitable only for applications where 8 PPR resolution is acceptable. System design review is required before substitution.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 26GS22-01-1-16S-F, 26GS22-01-1-16S-C, 26GSD22-01-1-AJS, and 26GSD45-01-1-AJS are all RoHS compliant and REACH unaffected. Moisture sensitivity level is MSL 1 (Unlimited) for all parts.

Q: What mounting configurations are supported by these encoders?

A: All parts support panel and PCB through-hole mounting with vertical orientation. The 1/8" diameter flatted end actuator is standard across all substitute parts.

Q: Which substitute part has the highest current inventory availability?

A: The 26GS22-01-1-16S-C has the highest inventory at 1802 pieces. The 26GSD22-01-1-AJS has 1363 pieces, and the 26GSD45-01-1-AJS has 1144 pieces available.
