IMN32188C Inductive Proximity Sensor - Equivalent & Substitute Parts

Part Overview

The IMN32188C is an inductive proximity sensor manufactured by Crouzet, designed for non-contact detection of metallic objects at 8mm sensing distance. This sensor features a cylindrical M18 threaded housing with PNP-NO output configuration and operates 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 type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IMN32188C is determined by strict equivalence across the following critical parameters:

• Sensor Type: Inductive (detection principle must remain unchanged)
• Sensing Distance: 0.315" (8mm) (detection range must match application requirements)
• Output Configuration: PNP-NO, 3-Wire (electrical interface compatibility)
• Supply Voltage Range: 10V ~ 30V (power supply compatibility)
• Shielding: Shielded (electromagnetic interference rejection)
• Housing: Cylinder, Threaded - M18 (mechanical mounting compatibility)
• Ingress Protection: IP67 (environmental sealing requirement)
• Termination: Cable Leads (connection method)

The substitute part E2B-M18LS08-WP-B1 5M meets all these critical parameters, enabling direct functional replacement in applications currently using the IMN32188C.

Engineering Selection Recommendations

The E2B-M18LS08-WP-B1 5M from Omron Automation and Safety is the qualified substitute for the obsolete IMN32188C. Selection is based on the following engineering criteria:

• Functional Equivalence: All critical electrical and mechanical parameters match the original specification, ensuring drop-in replacement capability.
• Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both the original and substitute part carry RoHS Compliant certification, meeting environmental and regulatory requirements.
• Certification Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8543.70.9860) classifications, maintaining compliance consistency.

Frequently Asked Questions (FAQ)

Q: Can the E2B-M18LS08-WP-B1 5M directly replace the IMN32188C in existing installations?

A: Yes. The substitute part matches all critical parameters including sensing distance, output type, supply voltage range, housing form factor, and environmental protection rating. Physical mounting and electrical connection are compatible.

Q: What is the significance of the "5M" designation in the E2B-M18LS08-WP-B1 5M part number?

A: The "5M" indicates the cable lead length is 5 meters. Verify that the cable length requirement of your application matches this specification before selection.

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

A: The IMN32188C does not specify a response frequency parameter. The E2B-M18LS08-WP-B1 5M specifies 500Hz response frequency. This specification does not affect substitution eligibility for applications using the original part.

Q: Do both sensors require the same mounting hardware?

A: Yes. Both sensors use M18 threaded cylindrical housing, requiring identical mounting fixtures and installation procedures.

Q: What compliance certifications apply to both parts?

A: Both the IMN32188C and E2B-M18LS08-WP-B1 5M are RoHS Compliant and carry identical ECCN and HTSUS classifications, ensuring regulatory consistency in applications requiring export or environmental compliance documentation.
