OMRON E3S

Printed Circuit Board Sensor
E3S-LS3N
Printed circuit board sensor
capable of stable detection
without being affected by
holes or notches.
● Suitable for incorporation in devices (E3S-LS3N).
● Wide range is suitable for component boards with
high or irregularly shaped components (E3SLS3NW).
