Frequently Asked Questions (FAQ)
The E2B-M12LS04-M1-B1 uses PNP (sourcing) output, which means the output switches the positive voltage. This is commonly used with PLCs that have sinking inputs. NPN (sinking) outputs switch the ground connection instead.
No, inductive proximity sensors like the E2B-M12LS04-M1-B1 can only detect metallic objects. For non-metallic object detection, capacitive or photoelectric sensors would be required.
Shielded sensors can be mounted flush with metal surfaces without affecting their sensing performance. Unshielded sensors require a clearance area around them when mounted in metal.
While the sensor itself doesn't have a strict cable length limit, for optimal performance in industrial environments, it's recommended to keep cable lengths under 100 meters and use shielded cables in electrically noisy environments.
You can test the sensor by applying power (10-30V DC) and bringing a metal target within the 4mm sensing range. The output should switch when the target is detected. A multimeter can be used to verify the output voltage change.
While the IP67 rating provides good protection against dust and temporary water immersion, for continuous outdoor exposure, additional protection from direct sunlight and extreme weather conditions is recommended.
