IMM23188C Inductive Proximity Sensor - Equivalent & Substitute Parts

Part Overview

The IMM23188C 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, operating across a 10V to 30V supply range. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and new design implementations where this sensor is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IMM23188C is determined by strict alignment of the following critical parameters:

• Sensor Type: Inductive (required for metallic object detection)
• Sensing Distance: 0.315" (8mm) (determines detection range and application compatibility)
• Output Type: NPN-NC, 3-Wire (ensures circuit compatibility with existing control systems)
• Shielding: Shielded (maintains electromagnetic immunity in industrial environments)
• Material - Body: Nickel-Plated Brass (provides corrosion resistance and mechanical durability)
• Voltage - Supply: 10V ~ 30V (ensures power supply compatibility)
• Termination Style: Cable Leads (maintains installation compatibility)
• Operating Temperature: -25°C ~ 70°C (defines environmental operating range)
• Ingress Protection: IP67 (ensures sealed operation in wet/dusty conditions)
• Package / Case: Cylinder, Threaded - M18 (ensures mechanical fit in existing mounting)

The E2B-M18KS08-WP-C2 2M from Omron Automation and Safety meets all these critical parameters and qualifies as a direct functional equivalent.

Engineering Selection Recommendations

The E2B-M18KS08-WP-C2 2M is the qualified substitute for the obsolete IMM23188C. Selection is based on:

• Product Status Alignment: The substitute is Active status, ensuring continued availability and manufacturer support, whereas the original is Obsolete.
• Regulatory Compliance: Both parts maintain RoHS compliance. The substitute achieves ROHS3 Compliant status, representing current regulatory standards. The substitute is REACH Unaffected, confirming no restricted substance concerns.
• Functional Equivalence: All critical electrical and mechanical parameters match exactly, including sensing distance, output configuration, supply voltage range, operating temperature, and mechanical form factor.
• Certification Alignment: Both parts carry identical ECCN (EAR99) and HTSUS (8543.70.9860) classifications, confirming trade compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can the E2B-M18KS08-WP-C2 2M be used as a direct replacement for the IMM23188C?

A: Yes. Both sensors share identical sensing distance (8mm), output type (NPN-NC, 3-Wire), supply voltage range (10V ~ 30V), operating temperature (-25°C ~ 70°C), mechanical package (M18 threaded cylinder), and ingress protection (IP67). Direct substitution is supported without circuit modification.

Q: What is the significance of the Response Frequency specification on the substitute part?

A: The E2B-M18KS08-WP-C2 2M specifies 500Hz response frequency. This parameter was not provided for the original IMM23188C. Response frequency defines the maximum switching speed of the sensor. The 500Hz specification on the substitute indicates capability for applications requiring moderate switching speeds in industrial automation.

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

A: Both parts are RoHS compliant. The substitute achieves ROHS3 Compliant status, representing the current regulatory iteration. The substitute carries REACH Unaffected status, confirming no restricted substances under REACH regulations. Both share identical trade classifications (ECCN: EAR99, HTSUS: 8543.70.9860).

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

A: Yes. Both sensors use identical M18 threaded cylinder packaging. This ensures mechanical fit in existing mounting fixtures, sensor holders, and enclosure penetrations without modification.

Q: What is the cable lead termination configuration?

A: Both sensors use cable leads for termination, providing flexible installation in field wiring applications. The 2M designation on the substitute indicates a 2-meter cable length. Verify cable length requirements for your specific installation.
