IMM2684C Inductive Proximity Sensor - Equivalent & Substitute Parts

Part Overview

The IMM2684C is an inductive proximity sensor manufactured by Crouzet, designed for non-contact detection of metallic objects at a 4mm sensing distance. This cylindrical M8-threaded 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 components essential for system maintenance, repair, and new installations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IMM2684C is determined by strict equivalence across the following critical parameters:

• Sensor Type: Inductive technology for metallic object detection
• Sensing Distance: 0.157" (4mm) detection range
• Output Configuration: NPN-NC, 3-Wire logic
• Supply Voltage Range: 10V ~ 30V DC compatibility
• Physical Form Factor: Cylinder, Threaded M8 package
• Environmental Rating: IP67 protection level
• Operating Temperature Range: -25°C ~ 70°C
• Termination: Cable leads connection method

The E2B-S08KN04-WP-C2 2M from Omron Automation and Safety meets all these critical parameters and is classified as an active product with current manufacturing support.

Engineering Selection Recommendations

The E2B-S08KN04-WP-C2 2M is the direct functional equivalent for IMM2684C replacement applications. Selection is based on the following engineering criteria:

Product Status: The IMM2684C is obsolete with no active manufacturing. The E2B-S08KN04-WP-C2 2M maintains active product status with current inventory availability, ensuring long-term supply chain reliability.

Regulatory Compliance: Both sensors meet RoHS requirements. The substitute part carries ROHS3 compliance certification, representing current regulatory standards. The E2B-S08KN04-WP-C2 2M also maintains REACH Unaffected status, confirming compliance with European chemical regulations.

Electrical and Mechanical Equivalence: All critical operating parameters are identical across both sensors, including sensing distance, output logic, supply voltage range, and environmental protection rating. Physical form factor compatibility is confirmed through identical M8 threaded cylinder packaging.

Response Frequency: The E2B-S08KN04-WP-C2 2M specifies 1kHz response frequency, providing documented switching speed performance not listed for the obsolete IMM2684C.

Frequently Asked Questions (FAQ)

Q: Can the E2B-S08KN04-WP-C2 2M directly replace the IMM2684C in existing installations?

A: Yes. Both sensors share identical electrical specifications (10V ~ 30V supply, NPN-NC 3-wire output), mechanical form factor (M8 threaded cylinder), and environmental ratings (IP67, -25°C ~ 70°C). Cable lead termination and 4mm sensing distance are equivalent. Direct mechanical and electrical substitution is supported.

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

A: The "2M" suffix indicates a 2-meter cable lead length. This specification applies to the termination style and does not affect electrical or sensing characteristics relevant to substitution compatibility.

Q: Are there differences in body material between these sensors?

A: Yes. The IMM2684C uses nickel-plated brass construction, while the E2B-S08KN04-WP-C2 2M uses stainless steel. Both materials provide corrosion resistance suitable for IP67-rated industrial environments. Material selection should be evaluated based on specific application environment and chemical exposure requirements.

Q: What does the response frequency specification mean for substitution?

A: Response frequency (1kHz for the E2B-S08KN04-WP-C2 2M) defines the maximum switching speed of the sensor output. This parameter does not affect basic substitution compatibility but should be verified against application timing requirements if the original IMM2684C specification is known.

Q: Is the E2B-S08KN04-WP-C2 2M the only substitute available?

A: Based on the provided data, the E2B-S08KN04-WP-C2 2M is the documented substitute meeting all critical parameter requirements for IMM2684C replacement.
