Printed Circuit Board Sensor
E3S-LS3
Printed circuit board
sensor capable of sta-
ble detection without
being affected by
holes or notches.
• Suitable for incorporation in devices
(E3S-LS3@).
• Wide range is suitable for component
boards with high or irregularly shaped
components (E3S-LS3@W).
Applications
Detecting for PCBs Transparent Film Sheet
