E3FJ12-LT30M Laser Through-Beam Photoelectric Sensor
Uses a visible red laser beam between a separate emitter and receiver for non-contact object detection. The visible beam assists optical alignment during installation. Objects are detected by interrupting the beam, making this arrangement suitable for counting and presence detection across equipment openings. The M12 nickel-plated brass housing, pre-wired connection and operation indicator support installation and commissioning.
