• Output Type: Both provide NPN-NC, 3-Wire configuration
• Voltage Supply Range: Both operate within 10V ~ 30V
• Shielding: Both are shielded designs
• Termination Style: Both use cable leads
• Operating Temperature Range: Both support -25°C ~ 70°C
• Ingress Protection: Both meet IP67 rating
• Indicator: Both include LED indication
• Package / Case: Both use cylindrical form factor
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)
• Export Classification: Both classified as EAR99
• HTSUS Code: Both share 8543.70.9860

Allowable Parameter Variations:

• Sensing Distance: E2E-C04S12-WC-C2 2M provides 0.047" (1.2mm) versus 0.039" (1mm) on the original
• Response Frequency: E2E-C04S12-WC-C2 2M operates at 4kHz versus 3kHz on the original
• Material - Body: E2E-C04S12-WC-C2 2M uses stainless steel versus nickel-plated brass on the original

Engineering Selection Recommendations

The E2E-C04S12-WC-C2 2M is the designated substitute for the obsolete E2E-C1C2. Selection of this substitute is supported by the following factors:

Product Status: The E2E-C04S12-WC-C2 2M maintains active production status, ensuring ongoing availability and supply chain continuity. The original E2E-C1C2 is obsolete and subject to inventory depletion.

Functional Equivalence: Both sensors maintain identical electrical interface specifications (NPN-NC, 3-Wire output) and operate within the same voltage supply range (10V ~ 30V), ensuring direct compatibility with existing control circuits and wiring harnesses.

Environmental Compliance: Both components share identical ingress protection rating (IP67), operating temperature range (-25°C ~ 70°C), and moisture sensitivity classification (MSL 1), confirming suitability for equivalent environmental conditions.

Export and Trade Classification: Both parts carry identical ECCN (EAR99) and HTSUS (8543.70.9860) classifications, maintaining consistent regulatory and customs treatment.

Material Upgrade: The substitute features stainless steel body construction versus nickel-plated brass on the original, providing enhanced corrosion resistance in industrial environments.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the E2E-C1C2 and E2E-C04S12-WC-C2 2M?

A: The sensing distance differs by 0.008" (0.2mm), with the substitute providing 1.2mm detection range versus 1mm on the original. The substitute also operates at 4kHz response frequency compared to 3kHz, and uses stainless steel body material instead of nickel-plated brass.

Q: Can the E2E-C04S12-WC-C2 2M be used as a direct replacement in existing installations?

A: Yes. Both sensors provide identical output type (NPN-NC, 3-Wire), voltage supply range (10V ~ 30V), and termination style (cable leads). The electrical interface and control circuit compatibility are maintained.

Q: Does the increased sensing distance of the substitute affect system performance?

A: The 0.2mm increase in sensing distance (1mm to 1.2mm) represents a 20% change in detection range. System performance impact depends on application-specific mounting geometry and target material properties. Applications with tight tolerance requirements should evaluate this parameter against specific installation constraints.

Q: Are there any compliance or certification differences between these parts?

A: Both components share identical ingress protection (IP67), operating temperature range (-25°C ~ 70°C), moisture sensitivity level (MSL 1), ECCN classification (EAR99), and HTSUS code (8543.70.9860). No compliance or certification differences exist.

Q: Why is the original E2E-C1C2 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The E2E-C04S12-WC-C2 2M represents the active production equivalent within the E2E series, ensuring long-term component availability and supply chain stability.

Q: What is the significance of the stainless steel body material on the substitute?

A: Stainless steel provides superior corrosion resistance compared to nickel-plated brass, particularly in environments with moisture, salt spray, or chemical exposure. This material upgrade enhances sensor durability in harsh industrial conditions.

Q: How does the 4kHz response frequency of the substitute compare to the 3kHz of the original?

A: The higher response frequency (4kHz versus 3kHz) indicates faster detection switching capability. This improvement supports applications requiring higher detection speed without compromising compatibility with standard industrial control systems.
