Key Parameters

Substitute Part Grouping Explanation

Substitute components for the IMM3281M8 are identified based on strict equivalence of the following critical parameters:

• Sensor Type: Inductive
• Sensing Distance: 0.039" (1mm)
• Output Type: PNP-NO, 3-Wire
• Package / Case: Cylinder, Threaded - M8
• Shielding: Shielded
• Termination Style: Connector
• Ingress Protection: IP67 (minimum)
• Voltage Supply: Compatible range (10V ~ 30V minimum coverage)
• RoHS Compliance: RoHS Compliant

The E2A-S08KS01-M3-B1 OMS from Omron Automation and Safety meets all substitution criteria. This part maintains identical sensor functionality, mechanical form factor, electrical output characteristics, and environmental protection ratings. The substitute part is classified as active product status, ensuring ongoing availability and technical support.

Parameter Comparison

Engineering Selection Recommendations

The E2A-S08KS01-M3-B1 OMS is a direct functional equivalent for the obsolete IMM3281M8. Selection of this substitute is supported by:

• Identical sensor type, sensing distance, and output configuration
• Mechanical compatibility through matching M8 threaded cylindrical form factor
• Equivalent or superior environmental protection (IP67 minimum, with additional IP69K rating)
• Extended operating temperature range (-40°C vs. -25°C lower limit)
• Expanded voltage supply range (10V ~ 32V vs. 10V ~ 30V)
• Active product status ensuring component availability and manufacturer support
• RoHS compliance maintained across both parts

The substitute part is suitable for direct replacement in existing applications and for new designs requiring equivalent inductive proximity sensing functionality.

Frequently Asked Questions (FAQ)

Q: Can the E2A-S08KS01-M3-B1 OMS replace the IMM3281M8 in existing installations?

A: Yes. Both parts share identical sensor type, sensing distance, output type, and M8 threaded mechanical form factor. The substitute part maintains connector-based termination and LED indicator functionality. Electrical compatibility is confirmed through overlapping voltage supply ranges and equivalent operating temperature performance within the original specification window.

Q: What are the key differences between these two parts?

A: The substitute part offers extended operating temperature range (-40°C minimum vs. -25°C), expanded voltage supply tolerance (10V ~ 32V vs. 10V ~ 30V), and additional IP69K ingress protection rating. Material composition differs (stainless steel body vs. nickel-plated brass), and product status transitions from obsolete to active.

Q: Are there mechanical compatibility concerns with the M8 threaded connection?

A: No. Both parts use identical M8 threaded cylindrical packaging. Connector-based termination is maintained in the substitute part, ensuring compatibility with existing wiring harnesses and connector interfaces.

Q: Does the substitute part maintain RoHS compliance?

A: Yes. The E2A-S08KS01-M3-B1 OMS is RoHS compliant, matching the compliance status of the original IMM3281M8.

Q: What is the significance of the active product status for the substitute part?

A: Active product status indicates ongoing manufacturer support, technical documentation availability, and supply chain continuity. This contrasts with the obsolete status of the original part, ensuring long-term component availability for maintenance and future production requirements.
