IMN23124C Inductive Proximity Sensor - Equivalent & Substitute Parts

Part Overview

The IMN23124C is an inductive proximity sensor manufactured by Crouzet, designed for non-contact detection of metallic objects at a 4mm sensing distance. This cylindrical, threaded M12 sensor operates with NPN-NC output configuration and is rated for industrial environments with IP67 ingress protection. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IMN23124C is determined by strict equivalence across the following critical parameters:

• Sensor Type: Inductive (detection principle must remain unchanged)
• Sensing Distance: 0.157" (4mm) (detection range must be identical)
• Output Type: NPN-NC, 3-Wire (electrical interface and logic state must match)
• Shielding: Shielded (electromagnetic interference rejection must be equivalent)
• Material - Body: Nickel-Plated Brass (environmental resistance and mechanical durability)
• Voltage - Supply: 10V ~ 30V (power supply compatibility)
• Termination Style: Cable Leads (connection method must be compatible)
• Operating Temperature: -25°C ~ 70°C (thermal operating range)
• Ingress Protection: IP67 (environmental sealing requirement)
• Package / Case: Cylinder, Threaded - M12 (mechanical form factor and mounting interface)

The E2B-M12KS04-WP-C2 2M from Omron Automation and Safety meets all these criteria and is classified as an active product with current manufacturing support.

Engineering Selection Recommendations

The E2B-M12KS04-WP-C2 2M is the direct equivalent substitute for the obsolete IMN23124C. Selection is based on the following engineering factors:

• Product Status: The substitute is an active product with current manufacturing support, ensuring long-term availability and supply chain continuity.
• Compliance: Both parts maintain RoHS compliance. The substitute achieves ROHS3 compliance, meeting current regulatory requirements.
• Electrical Equivalence: Identical voltage supply range (10V ~ 30V), output type (NPN-NC, 3-Wire), and operating temperature range (-25°C ~ 70°C) ensure direct functional replacement without circuit modification.
• Mechanical Compatibility: Identical M12 threaded cylindrical form factor and cable lead termination enable direct mechanical substitution in existing mounting configurations.
• Environmental Rating: Both sensors maintain IP67 ingress protection, suitable for industrial environments with moisture and dust exposure.

Frequently Asked Questions (FAQ)

Q: Can the E2B-M12KS04-WP-C2 2M be used as a direct replacement for the IMN23124C without circuit modifications?

A: Yes. Both sensors share identical electrical specifications: 10V ~ 30V supply voltage, NPN-NC 3-wire output configuration, and -25°C ~ 70°C operating temperature range. No circuit modifications are required.

Q: Are the mechanical mounting interfaces identical?

A: Yes. Both sensors use the M12 threaded cylindrical form factor with cable lead termination. Direct mechanical substitution is possible without adapter plates or mechanical modifications.

Q: What is the sensing distance for both sensors?

A: Both sensors have a sensing distance of 0.157" (4mm). Detection range is identical for metallic objects.

Q: Does the substitute sensor meet current environmental compliance standards?

A: Yes. The E2B-M12KS04-WP-C2 2M is ROHS3 compliant and maintains IP67 ingress protection, meeting current industrial environmental and regulatory requirements.

Q: Why is the IMN23124C listed as obsolete?

A: The IMN23124C is no longer manufactured by Crouzet. The E2B-M12KS04-WP-C2 2M from Omron provides equivalent functionality with active manufacturing support and availability.

Q: Is the response frequency specification critical for substitution?

A: The substitute specifies 1kHz response frequency. If the original IMN23124C application requires frequency response verification, the 1kHz specification of the substitute should be confirmed against system requirements. Both sensors are suitable for standard industrial proximity sensing applications.
