Norgren CS8-2-04 Reed Air Cylinder Reed Switch Nfpa

Product Description

The NORGREN CS8-2-04 REED is a reed switch accessory designed for use with pneumatic air cylinders. It mounts externally to the cylinder body and detects piston position without direct mechanical contact, sending a signal to indicate end-of-stroke or intermediate position. The switch is rated for bore sizes from 3/4 inches to 2-1/2 inches and carries a minimum operating temperature of -22 degrees F, making it suitable for cold-environment industrial and commercial pneumatic applications. Automation technicians, machine builders, and industrial maintenance technicians install this type of switch as part of position-sensing and control circuits on pneumatic actuator systems.

The CS8-2-04 REED is intended for use with 1-1/2 inch to 2-1/2 inch NFPA-style pneumatic cylinders. NFPA cylinders follow a standardized mounting and tie-rod envelope, and this switch is designed to fit the T-slot or groove profile common to that cylinder family. Typical applications include automated assembly equipment, material handling actuators, and process control pneumatics where piston position feedback is required for sequencing or safety interlock logic.

Key Features

• Reed switch design provides non-contact piston position detection
• Compatible with bore sizes from 3/4 inches to 2-1/2 inches
• Rated for use down to -22 degrees F for cold-environment installations
• Designed to mount on 1-1/2 inch to 2-1/2 inch NFPA-standard pneumatic cylinders
• Sold as a single unit accessory for targeted replacement or new installation

Compatibility

Designed for use with 1-1/2 inch to 2-1/2 inch NFPA-style pneumatic air cylinders with bore sizes ranging from 3/4 inches to 2-1/2 inches.

Installation Notes

Installation is typically performed by an automation technician or industrial electrician. De-energize all electrical circuits and exhaust pneumatic pressure from the cylinder before installing or replacing the switch. Secure the switch into the cylinder T-slot or mounting groove according to the cylinder manufacturer specifications and verify signal output before returning the system to service. Wiring should comply with applicable electrical codes for the control voltage class used in the circuit.
