IMN251816C Equivalent & Substitute Parts

Part Overview

The IMN251816C is an inductive proximity sensor manufactured by Crouzet, designed for industrial sensing applications requiring detection at 16mm sensing distance. This cylindrical M18-threaded sensor features NPN-NO output configuration with 3-wire termination via cable leads. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the IMN251816C are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires matching on the following parameters:

• Sensor Type: Inductive
• Sensing Distance: 0.630" (16mm)
• Output Type: NPN-NO, 3-Wire
• Voltage Supply Range: 10V ~ 30V
• Package / Case: Cylinder, Threaded - M18
• Shielding: Unshielded
• Material - Body: Nickel-Plated Brass
• Operating Temperature: -25°C ~ 70°C
• Ingress Protection: IP67
• Termination Style: Cable Leads
• Indicator: LED

The Omron Automation and Safety part E2B-M18KN16-WP-C1 2M satisfies all these parameters and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The E2B-M18KN16-WP-C1 2M from Omron Automation and Safety is the direct substitute for the obsolete IMN251816C. This substitution is supported by complete parameter equivalence across all electrical and mechanical specifications. The Omron part carries Active product status, ensuring ongoing availability and supply chain continuity. Both components meet RoHS compliance requirements, with the Omron part meeting the more recent ROHS3 standard. The Omron part additionally provides Response Frequency specification of 400Hz, which was not documented for the original Crouzet component.

Frequently Asked Questions (FAQ)

Q: Can the E2B-M18KN16-WP-C1 2M be used as a direct replacement for IMN251816C?

A: Yes. Both components share identical electrical specifications (10V ~ 30V supply, NPN-NO 3-wire output), mechanical form factor (M18 threaded cylinder), sensing distance (16mm), and environmental ratings (IP67, -25°C ~ 70°C). Physical installation and electrical connection are compatible.

Q: What is the significance of the "2M" designation in the Omron part number?

A: The "2M" indicates the cable lead length is 2 meters. This specification must be verified against system requirements during substitution.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant. The Omron part meets ROHS3 standard, representing a more recent compliance revision. The Omron part is also REACH Unaffected. Both carry identical ECCN (EAR99) and HTSUS (8543.70.9860) classifications.

Q: Why is the original IMN251816C listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Crouzet. The E2B-M18KN16-WP-C1 2M maintains Active status, confirming current production and availability from Omron.

Q: Are there any performance differences in response frequency?

A: The Omron E2B-M18KN16-WP-C1 2M specifies 400Hz response frequency. Response frequency was not documented for the original Crouzet component in available specifications.
