Photoelectric switch

MPN E18-DS30NA Sensors

This is an E18-DS30NA Photoelectric switch. It is a normally open NPN diffuse reflection type, meaning it outputs a low signal when an object is detected and operates by sensing light reflected from the target. This sensor is typically used for general object detection in automation.

About sensors

Photoelectric switch is listed under Sensors — proximity, photoelectric, ultrasonic, hall and limit sensors. Sensors in this category detect the presence or absence of objects without physical contact, or by contact in the case of limit switches. Proximity sensors, including inductive and capacitive types, respond to metallic and non-metallic objects respectively, typically within short ranges (1-50mm).
