Grayhill 62S18-M5-P Rotary Encoder Optical 20PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 62S18-M5-P is an optical rotary encoder with 20 pulses per revolution (PPR), delivering quadrature incremental output. This vertical-mount 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 mounted via PCB through-hole termination with PC pin connections.

The 62S18-M5-P maintains Active product status and holds ROHS3 compliance with REACH Unaffected designation. Substitute parts become necessary when application requirements specify different pulse resolution, inventory constraints exist, or alternative series configurations are required while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 62S18-M5-P are qualified based on strict alignment with the following critical parameters:

Mandatory Compatibility 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 (Cycles Min): 1M
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Variable Parameter (Substitution Basis):

• Pulses per Revolution: 12, 16, or 20

The substitute parts 62S22-M5-P and 62N30-P differ only in pulse resolution (16 PPR and 12 PPR respectively) while maintaining identical electrical supply, mechanical mounting, actuator configuration, and regulatory compliance. These parts are interchangeable when application firmware or signal processing can accommodate the alternative pulse count.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and identical regulatory compliance profiles (ROHS3 Compliant, REACH Unaffected). Selection between 62S18-M5-P, 62S22-M5-P, and 62N30-P depends solely on pulse resolution requirements:

62S18-M5-P (20 PPR): Primary selection for applications requiring 20 pulses per revolution resolution. Highest inventory availability at 1,061 pieces.

62S22-M5-P (16 PPR): Substitute when 16 pulses per revolution resolution satisfies application requirements. Highest inventory availability at 1,309 pieces.

62N30-P (12 PPR): Substitute when 12 pulses per revolution resolution satisfies application requirements. Inventory availability at 755 pieces.

All parts share identical electrical supply voltage (5V), mechanical mounting configuration (PCB through-hole), actuator geometry (1/4" flatted end), and operational life rating (1M cycles minimum). Substitution is valid when the receiving system firmware or signal processing accommodates the alternative pulse count without modification to electrical interface or mechanical mounting.

Frequently Asked Questions (FAQ)

Q: Can 62S22-M5-P replace 62S18-M5-P in existing designs?

A: Substitution is valid only when the application firmware or signal processing can accommodate 16 pulses per revolution instead of 20. The electrical interface, supply voltage, mounting configuration, and mechanical actuator are identical. No hardware modification is required.

Q: What is the primary difference between these substitute parts?

A: The sole difference is pulse resolution: 62S18-M5-P delivers 20 PPR, 62S22-M5-P delivers 16 PPR, and 62N30-P delivers 12 PPR. All other electrical, mechanical, and regulatory parameters are identical.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts (62S18-M5-P, 62S22-M5-P, and 62N30-P) are ROHS3 Compliant with REACH Unaffected status.

Q: Do these encoders require different supply voltages?

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

Q: What mounting configuration do these encoders use?

A: All three parts use PCB through-hole mounting with PC pin termination in vertical orientation. Mechanical mounting is identical across all substitute options.

Q: Is the actuator geometry the same across all substitute parts?

A: Yes. All three parts feature a 1/4" diameter flatted end actuator. Mechanical coupling and shaft interface are identical.

Q: Do these encoders include detent and switch functionality?

A: Yes. All three parts include both detent mechanism and built-in switch functionality.

Q: What is the minimum rotational life rating for these encoders?

A: All three parts are rated for a minimum of 1 million (1M) rotational cycles.
