Proximity Switch Photoelectric Switch Sensor LJ12A34Z/BY – PNP Type

The Proximity Switch Photoelectric Switch Sensor LJ12A34Z/BY – PNP Type is a non-contact inductive proximity sensor designed to detect metal objects without physical contact. It generates a digital output signal when a target comes within its sensing range. The PNP output configuration sources current, making it compatible with PLCs and microcontroller input circuits requiring positive switching signals.

This sensor is suitable for industrial automation, conveyor systems, robotics, position detection, and object presence monitoring. The compact cylindrical housing and PNP output make it easy to install and integrate in control systems and embedded projects.
