Grayhill 62P22-L4 Rotary Encoder Optical 16PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 62P22-L4 is an optical rotary encoder with 16 pulses per revolution (PPR) in quadrature (incremental) output configuration. This component operates at 5V supply voltage and features a vertical orientation with PCB through-hole mounting and PC pin termination. The encoder includes an integrated detent mechanism and built-in switch functionality.

The 62P22-L4 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or maintenance requirements for systems utilizing this encoder.

Mechanical Considerations: Substitute parts may differ in actuator diameter and mounting type while maintaining functional equivalence, provided all core electrical and output characteristics remain identical.

Parameter Comparison

Engineering Selection Recommendations

The Grayhill 62AG22-L5-P serves as a functional equivalent to the obsolete 62P22-L4 based on matching core electrical and output specifications. Both encoders share identical encoder type (optical), output configuration (quadrature incremental), resolution (16 PPR), supply voltage (5V), and termination style (PC pin).

Compliance Advantages: The 62AG22-L5-P holds ROHS3 Compliant status, exceeding the RoHS Compliant rating of the 62P22-L4. Both parts maintain REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity classification.

Performance Advantages: The 62AG22-L5-P provides 1M rotational life cycles, doubling the 500K minimum specification of the 62P22-L4, indicating enhanced mechanical durability.

Mechanical Differences: The substitute part features a 1/4" diameter flatted-end actuator compared to the 3/16" diameter of the original part. The 62AG22-L5-P utilizes panel mount configuration versus the PCB through-hole mounting of the 62P22-L4. These mechanical differences require mechanical design review to confirm fit within the target application enclosure and mounting structure.

Availability: The 62AG22-L5-P maintains active product status with 882 units in stock, ensuring supply continuity for new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the 62AG22-L5-P directly replace the 62P22-L4 in existing PCB designs?

A: Electrical substitution is valid; the encoders share identical output type, resolution, voltage, and termination. However, mechanical substitution requires design modification. The 62AG22-L5-P uses panel mount configuration instead of PCB through-hole mounting, and features a larger 1/4" actuator diameter versus 3/16". Mechanical redesign of the mounting interface is necessary.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts maintain REACH Unaffected and MSL 1 (Unlimited) status. The 62AG22-L5-P holds ROHS3 Compliant certification, which exceeds the RoHS Compliant rating of the 62P22-L4. This represents an improvement in environmental compliance.

Q: What is the significance of the different rotational life specifications?

A: The 62AG22-L5-P specifies 1M rotational life cycles compared to 500K for the 62P22-L4. This indicates the substitute part has been tested and rated for extended mechanical durability. Applications requiring high-cycle operation benefit from this enhanced specification.

Q: How do the different actuator diameters affect mechanical compatibility?

A: The 62AG22-L5-P uses a 1/4" diameter flatted-end actuator versus 3/16" on the 62P22-L4. This 1/16" diameter increase affects coupling selection, shaft bore sizing, and mechanical clearances. Mechanical design review is required to confirm fit within the application's mechanical envelope.

Q: Is the 62AG22-L5-P suitable for new product designs?

A: Yes. The 62AG22-L5-P holds active product status with confirmed inventory availability. It meets all core electrical and output requirements for optical quadrature encoder applications at 5V supply. Mechanical integration must be evaluated based on specific application mounting and actuator requirements.
