IMM25128C Equivalent & Substitute Parts

Part Overview

The IMM25128C is an inductive proximity sensor manufactured by Crouzet, designed for non-contact detection applications with an 8mm sensing distance. This cylindrical, threaded M12 sensor operates across a 10V to 30V supply range and provides NPN-NO output through 3-wire 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

Substitution of the IMM25128C is determined by strict equivalence across the following critical parameters:

• Sensor Type: Must be Inductive
• Sensing Distance: Must be 0.315" (8mm)
• Output Configuration: Must be NPN-NO, 3-Wire
• Voltage Supply Range: Must support 10V ~ 30V
• Operating Temperature Range: Must support -25°C ~ 70°C
• Ingress Protection: Must be IP67
• Package / Case: Must be Cylinder, Threaded - M12
• Termination: Must be Cable Leads
• Body Material: Must be Nickel-Plated Brass
• Shielding: Must be Unshielded

The E2B-M12KN08-WP-C1 2M from Omron Automation and Safety meets all specified parameters and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The E2B-M12KN08-WP-C1 2M is a direct functional equivalent to the obsolete IMM25128C. Both sensors share identical electrical specifications, mechanical form factors, and environmental ratings. The Omron substitute carries active product status with ROHS3 compliance, providing regulatory advantage over the obsolete Crouzet original. The E2B-M12KN08-WP-C1 2M is available in higher inventory quantities (1297 units) compared to the original part, supporting both immediate replacement needs and future procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the E2B-M12KN08-WP-C1 2M directly replace the IMM25128C in existing installations?

A: Yes. Both sensors are identical in sensing distance (8mm), output type (NPN-NO, 3-Wire), voltage supply range (10V ~ 30V), operating temperature (-25°C ~ 70°C), ingress protection (IP67), and M12 threaded cylindrical package. Cable lead termination and mechanical dimensions are equivalent.

Q: What is the significance of the response frequency specification for the Omron substitute?

A: The E2B-M12KN08-WP-C1 2M specifies a response frequency of 800Hz. This parameter was not provided for the original IMM25128C. The 800Hz response frequency of the substitute is suitable for standard industrial inductive sensing applications and does not restrict compatibility with typical control circuits.

Q: Are there compliance differences between the two sensors?

A: The original IMM25128C carries RoHS Compliant status. The Omron E2B-M12KN08-WP-C1 2M carries ROHS3 Compliant status, representing a more current regulatory standard. Both sensors meet RoHS requirements and are suitable for applications with environmental compliance mandates.

Q: Why is the IMM25128C listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Crouzet. The E2B-M12KN08-WP-C1 2M from Omron maintains active production status, ensuring long-term availability and supply chain continuity.

Q: Are there any mechanical installation differences?

A: No. Both sensors use identical M12 threaded cylindrical packages with cable lead termination. Installation procedures, mounting hardware, and connector compatibility remain unchanged.
