Engineering Selection Recommendations

The E2E-C04S12-MC-C1 is the designated substitute for the obsolete E2E-C1C1-R. Selection of this substitute is based on:

• Product Status: The substitute maintains active product status, ensuring continued availability and supply chain reliability.
• Electrical Compatibility: Both sensors operate within the same voltage supply range (10V ~ 30V) and provide identical NPN-NO, 3-wire output configuration, enabling direct functional replacement in existing circuits.
• Environmental Specifications: Identical operating temperature range (-25°C ~ 70°C) and IP67 ingress protection rating ensure equivalent performance in industrial environments.
• Export Classification: Both parts share the same ECCN (EAR99) and HTSUS codes, maintaining regulatory compliance for international distribution.

The 0.2mm increase in sensing distance (1.2mm vs. 1mm) and the change from cable leads to connector termination require mechanical and installation verification in the target application. The stainless steel body material of the substitute provides enhanced corrosion resistance compared to the nickel-plated brass of the original part.

Frequently Asked Questions (FAQ)

Q: Can the E2E-C04S12-MC-C1 directly replace the E2E-C1C1-R in all applications?

A: The substitute provides electrical and environmental compatibility. However, the 0.2mm difference in sensing distance and the change from cable leads to connector termination require verification against specific application requirements. Mechanical mounting and wiring interface must be confirmed before implementation.

Q: What is the significance of the sensing distance difference between the two sensors?

A: The E2E-C1C1-R operates at 1mm sensing distance, while the E2E-C04S12-MC-C1 operates at 1.2mm. This 0.2mm difference affects the maximum distance at which the sensor detects ferrous metal objects. Applications with tight spatial constraints or precise detection requirements must account for this parameter variation.

Q: Why does the substitute use a connector termination instead of cable leads?

A: The E2E-C04S12-MC-C1 employs connector-based termination, whereas the original E2E-C1C1-R uses cable leads. This design change requires compatible connector hardware and may necessitate modifications to existing wiring harnesses or connection infrastructure.

Q: Are there compliance or certification differences between these sensors?

A: Both sensors share identical ECCN (EAR99) and HTSUS classifications. The substitute is RoHS non-compliant, which should be evaluated against your system's regulatory requirements.

Q: What is the response frequency difference, and does it affect substitution suitability?

A: The E2E-C04S12-MC-C1 operates at 4kHz response frequency compared to the 3kHz of the E2E-C1C1-R. This 1kHz increase provides faster detection response and is generally compatible with applications designed for the original 3kHz specification.
