The CKD T Series reed 2-wire cylinder switch senses piston position in magnet-equipped pneumatic cylinders. It provides a contact signal to controllers for confirming stroke end positions. It is used throughout automated assembly and handling equipment. The switch is fixed with a band or rail mount so the detection point can be adjusted along the cylinder body as needed.
