IMN251816P Equivalent & Substitute Parts

Part Overview

The IMN251816P is an inductive proximity sensor manufactured by Crouzet, designed for non-contact detection applications with a 16mm cylindrical form factor. This sensor operates as a 3-wire NPN normally open (NO) output device with a sensing distance of 0.630" (16mm). The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and component sourcing in ongoing applications.

Key Parameters

Substitute Part Grouping Explanation

The E2B-M18LN16-M1-C1 from Omron Automation and Safety qualifies as a direct substitute for the IMN251816P based on the following critical parameters:

• Sensor Type: Both are inductive proximity sensors
• Sensing Distance: Identical at 0.630" (16mm)
• Output Configuration: Both provide NPN-NO, 3-Wire output
• Supply Voltage Range: Both operate within 10V ~ 30V
• Mechanical Form Factor: Both use M18 threaded cylinder packaging
• Body Material: Both feature nickel-plated brass construction
• Environmental Rating: Both meet IP67 ingress protection
• Termination: Both use connector-based termination
• Operating Temperature Range: Both function across -25°C ~ 70°C
• Shielding: Both are unshielded designs

These parameters define the functional and mechanical compatibility requirements for inductive proximity sensor substitution in this category.

Parameter Comparison

Engineering Selection Recommendations

The E2B-M18LN16-M1-C1 is the appropriate substitute for the obsolete IMN251816P. The Omron component maintains active product status, ensuring ongoing availability and supply chain continuity. Both components meet identical electrical and mechanical specifications across all critical parameters. The Omron part carries ROHS3 compliance, which exceeds the RoHS compliance of the original Crouzet sensor, providing enhanced environmental and regulatory alignment. The specified response frequency of 400Hz for the Omron component represents an additional performance characteristic not documented for the original part, supporting applications requiring defined switching speeds.

Frequently Asked Questions (FAQ)

Q: Can the E2B-M18LN16-M1-C1 be used as a direct replacement for the IMN251816P?

A: Yes. Both sensors share identical sensing distance (16mm), output configuration (NPN-NO, 3-Wire), supply voltage range (10V ~ 30V), mechanical form factor (M18 threaded cylinder), and environmental specifications (IP67, -25°C ~ 70°C operating range). Connector-based termination is identical on both components.

Q: What is the primary reason to substitute the IMN251816P?

A: The IMN251816P is obsolete. The E2B-M18LN16-M1-C1 provides an active, continuously available alternative with equivalent functional and mechanical characteristics.

Q: Are there any differences in compliance or certifications?

A: The E2B-M18LN16-M1-C1 carries ROHS3 compliance compared to RoHS compliance on the original part. Both components are EAR99 classified and share identical HTSUS codes (8543.70.9860).

Q: Does the M18 threaded cylinder packaging ensure mechanical compatibility?

A: Yes. Both components use identical M18 threaded cylinder packaging with connector-based termination, ensuring direct mechanical and electrical integration into existing mounting and wiring configurations.

Q: What is the significance of the 400Hz response frequency specification on the Omron part?

A: The 400Hz response frequency defines the switching speed capability of the E2B-M18LN16-M1-C1. This parameter was not specified for the original IMN251816P but represents a documented performance characteristic of the substitute component.
