IMN26128C Inductive Proximity Sensor - Equivalent & Substitute Parts

Part Overview

The IMN26128C is an inductive proximity sensor manufactured by Crouzet, designed for non-contact detection of metallic objects at 8mm sensing distance. This sensor features NPN-NC output configuration with 3-wire termination via cable leads and operates across a 10V to 30V supply voltage range. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for system maintenance, repair, and new design implementations where this specific model is no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IMN26128C is determined by strict alignment of the following critical parameters:

• Sensor Type: Inductive (detection principle must remain unchanged)
• Sensing Distance: 0.315" (8mm) (detection range must match application requirements)
• Output Type: NPN-NC, 3-Wire (electrical interface and logic state must be compatible)
• Voltage - Supply: 10V ~ 30V (power supply compatibility)
• Termination Style: Cable Leads (physical connection method)
• Operating Temperature: -25°C ~ 70°C (environmental operating range)
• Ingress Protection: IP67 (environmental sealing requirement)
• Package / Case: Cylinder, Threaded - M12 (mechanical form factor and mounting)
• Material - Body: Nickel-Plated Brass (corrosion resistance and material compatibility)
• Shielding: Unshielded (electromagnetic interference characteristics)

The Omron Automation and Safety E2B-M12LN08-WP-C2 2M meets all specified parameters and qualifies as a direct functional equivalent.

Engineering Selection Recommendations

The E2B-M12LN08-WP-C2 2M from Omron Automation and Safety is the qualified substitute for the obsolete IMN26128C. Selection is based on:

• Parameter Equivalence: All critical electrical, mechanical, and environmental parameters match the original specification.
• Product Status: The substitute maintains active product status, ensuring continued availability and support.
• Compliance: Both components maintain RoHS compliance and equivalent regulatory classification (ECCN: EAR99; HTSUS: 8543.70.9860).
• Response Frequency: The substitute provides specified response frequency of 800Hz, enabling predictable switching performance in control applications.

Direct substitution is appropriate for replacement applications where the IMN26128C is no longer procurable.

Frequently Asked Questions (FAQ)

Q: Can the E2B-M12LN08-WP-C2 2M be used as a direct replacement for IMN26128C?

A: Yes. Both sensors share identical specifications across all critical parameters: 8mm sensing distance, NPN-NC 3-wire output, 10V–30V supply voltage, M12 threaded cylinder package, IP67 ingress protection, and operating temperature range of -25°C to 70°C.

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

A: The "2M" indicates a 2-meter cable lead length. Verify that the cable length requirement matches your application before selection.

Q: Are there any differences in response frequency between these sensors?

A: The IMN26128C does not specify response frequency in the provided data. The E2B-M12LN08-WP-C2 2M specifies 800Hz response frequency. Confirm that this switching speed is compatible with your control circuit requirements.

Q: Do both sensors use the same mounting interface?

A: Yes. Both employ M12 threaded cylinder mounting, allowing direct mechanical interchange without modification to mounting hardware.

Q: What is the difference in product status, and does it affect substitution?

A: The IMN26128C is classified as obsolete, while the E2B-M12LN08-WP-C2 2M maintains active status. Active status ensures ongoing availability, technical support, and compliance with current manufacturing standards.

Q: Are cable lead connections compatible between these sensors?

A: Both sensors use cable leads for termination. Verify wire gauge, connector type, and pinout configuration against your application schematic before installation.
