Grayhill 61KS32 Rotary Encoder Optical 32PPR - Equivalent & Substitute Parts

Part Overview

The Grayhill 61KS32 is an optical rotary encoder with 32 pulses per revolution (PPR), providing quadrature (incremental) output. This vertical-mount encoder operates at 5V supply voltage and features a 1/4" diameter flatted end actuator. The device is designed for panel and PCB through-hole mounting applications with PC pin termination. The 61KS32 maintains active product status with 887 units in current inventory and demonstrates ROHS3 compliance and REACH unaffected status. Finding equivalent substitute parts becomes necessary when primary inventory is depleted, when supply chain disruptions occur, or when design flexibility permits component standardization across multiple suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Grayhill 61KS32 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

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

The Bourns EM14A0D-C24-L032N meets all critical electrical and mechanical parameters required for direct substitution. Both components share identical functional specifications for encoder operation, signal output characteristics, and physical mounting requirements. Compliance certifications (ROHS3) are maintained across both parts, ensuring regulatory compatibility in target applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Grayhill 61KS32 and Bourns EM14A0D-C24-L032N are active products with current manufacturing status. Component selection between these parts should be based on availability and supply chain considerations. The Grayhill 61KS32 currently maintains 887 units in inventory, while the Bourns EM14A0D-C24-L032N maintains 1081 units. Both components satisfy ROHS3 compliance requirements and share identical export classification (EAR99) and tariff coding (8543.70.4500). The rotational life specification differs between manufacturers (10M cycles minimum for Grayhill versus 1M cycles minimum for Bourns); applications requiring extended operational life should reference the specific rotational life requirement against the selected component's rating.

Frequently Asked Questions (FAQ)

Q: Can the Bourns EM14A0D-C24-L032N directly replace the Grayhill 61KS32 in existing designs?

A: Yes. Both components share identical electrical output characteristics (32 PPR quadrature output at 5V), mechanical mounting specifications (vertical orientation, panel and PCB through-hole mounting), and physical actuator dimensions (1/4" diameter flatted end). PC pin termination is consistent across both parts.

Q: What is the difference in rotational life between these two encoders?

A: The Grayhill 61KS32 specifies a minimum rotational life of 10 million cycles, while the Bourns EM14A0D-C24-L032N specifies a minimum of 1 million cycles. Applications with extended operational requirements should account for this specification difference in component selection.

Q: Are both parts RoHS compliant?

A: Yes. Both the Grayhill 61KS32 and Bourns EM14A0D-C24-L032N are ROHS3 compliant and carry identical export classification (EAR99).

Q: What is the moisture sensitivity level for each part?

A: The Grayhill 61KS32 carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The Bourns EM14A0D-C24-L032N is listed as Not Applicable for moisture sensitivity level.

Q: Are there any REACH compliance differences between these parts?

A: Yes. The Grayhill 61KS32 is REACH Unaffected, while the Bourns EM14A0D-C24-L032N is REACH Affected. Applications subject to REACH regulations should verify compliance requirements against the specific component selected.

Q: Can these encoders be used interchangeably in PCB designs?

A: Yes, from a mechanical and electrical standpoint. Both components feature identical PC pin termination and mounting specifications (panel and PCB through-hole). PCB layout and footprint compatibility should be verified against manufacturer datasheets to ensure proper alignment.
