Product Description – Denki Seigyo DUP-30S / DUP-30S-P Fork Sensor
The Denki Seigyo DUP-30S series is a compact U-type fork photoelectric sensor designed for reliable and high-speed object detection in industrial automation applications. With a 30 mm slot gap, the emitter and receiver are integrated into a single housing, ensuring stable sensing without the need for alignment.
The sensor is ideal for detecting labels, films, small parts, and edges in packaging machines, conveyor systems, and printing equipment. Its robust industrial design and fast response time make it suitable for continuous operation in demanding manufacturing environments.
The series includes two output options: DUP-30S (NPN output) and DUP-30S-P (PNP output), allowing easy integration with different PLC and control systems.
With its compact structure, reliable performance, and simple installation, the DUP-30S fork sensor provides an efficient solution for precision detection in modern automation systems.
