Frequently Asked Questions (FAQ)

Q: Can the E2B-M18LN16-M1-C1 directly replace the IMN251816M12 in existing installations?

A: Yes. Both sensors share identical electrical output configuration (NPN-NO, 3-Wire), supply voltage range (10V ~ 30V), sensing distance (16mm), and M18 threaded connector interface. Physical and electrical compatibility is confirmed across all specified parameters.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The IMN251816M12 is classified as obsolete, indicating discontinued manufacturing and limited availability. The E2B-M18LN16-M1-C1 maintains active status, ensuring reliable sourcing, technical support, and supply chain availability for current and future applications.

Q: Are there differences in environmental protection between these sensors?

A: Both sensors maintain IP67 ingress protection rating, providing equivalent sealing against dust and temporary water immersion. Operating temperature ranges are identical (-25°C ~ 70°C).

Q: Does the connector termination style remain unchanged?

A: Yes. Both sensors utilize connector-based termination, maintaining compatibility with existing connector interfaces and wiring configurations.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 Compliant represents an updated compliance designation reflecting current regulatory standards. The E2B-M18LN16-M1-C1 meets enhanced environmental and material restriction requirements while maintaining full backward compatibility.
