FESTO SIEN4BPOKL PROXIMITY SWITCH

Description:

The Festo SIEN-4B-PO-K-L Proximity Switch is used in pneumatic automation and machine control systems to detect the presence and position of metallic objects without physical contact. Commonly installed in pneumatic cylinders, assembly equipment, packaging machinery, material handling systems, and automated production lines requiring reliable position sensing and feedback signals. Maintenance teams and system integrators use this part for sensor replacements, automation retrofits, machine repairs, and OEM equipment maintenance.

Applications:

The Festo SIEN-4B-PO-K-L proximity switch is commonly used to provide non-contact position sensing in industrial automation systems. Typical applications for the SIEN-4B-PO-K-L include pneumatic actuators, pick-and-place systems, packaging equipment, conveyor systems, robotic cells, and factory automation machinery requiring compact inductive sensing and high switching reliability. The sensor is particularly suited for installation in space-constrained applications due to its compact 4 mm design.
