Miller Edge PS20K500-18C 18ft Pneumatic Kits of RAH-500 Rubber Hose w/ Coil Cord
The Miller Edge PS20K500-18C pneumatic edge kit is used to assemble or repair a basic non-monitored air-activated sensing edge system. When the edge or hose is compressed, the air pressure wave is sent to a pneumatic switch, allowing the door or gate control circuit to stop and/or reverse when the operator is wired correctly.
This kit is tied to the Miller Edge PS20A pneumatic edge component family and uses RAH-500 1/2 in. inside-diameter gum rubber hose. The C suffix indicates the coil cord version, which is useful when the moving edge needs a flexible wired connection back to the operator controls.
Compatible With
- Miller Edge PS20A pneumatic edge switch applications using 1/2 in. RAH-500 gum rubber hose
- Miller Edge pneumatic configured sensing edges up to 18 ft. when the system is built for a PS20A style switch
- Select Miller Edge pneumatic treadle and signaling hose applications using compatible 1/2 in. air hose
- Commercial sectional doors, rolling doors, coiling grilles, sliding doors, and similar motorized door applications that were originally designed for non-monitored pneumatic edges
- Pre-2010 commercial door operators and pre-2016 gate operators where a non-monitored air-activated edge is allowed by the operator design and local requirements
- Secondary entrapment protection applications where a non-monitored pneumatic edge is allowed and properly connected
- Related PS20K500 kit family: PS20K500-12, PS20K500-12C, PS20K500-18, and PS20K500-18C
- Not a monitored 10K, 8.2K, 4-wire, wireless monitored, or Miller Edge RBand replacement

Technician Note
This kit should be matched to a pneumatic edge system, not an electric 2-wire, monitored 10K, or wireless monitored edge. If the existing installation has a resistor, monitored transmitter, edge module, or a newer operator requiring monitored entrapment protection, this kit may not be the correct replacement.
Before Ordering Checklist
- Confirm the original kit or hose size is PS20K500-18C or a compatible 18 ft. x 1/2 in. pneumatic kit.
- Check whether the moving edge needs the coil cord version.
- Confirm the connected switch is a PS20A style pneumatic switch or compatible pneumatic switch assembly.
- Confirm the operator accepts a non-monitored pneumatic safety edge on the intended input.
- Inspect the old hose, end plugs, coil cord, and switch tubing for cracks, leaks, and missing fittings.
Professional Advisory
Do not bypass a safety edge or leave a motorized door or gate operating without required entrapment protection. If the operator wiring, safety input type, or code requirement is unclear, have a qualified door or gate technician inspect the system before replacement.
Product Questions & Answers
Q: What comes with the PS20K500-18C kit?
A: The PS20K500-18C kit is listed with 18 ft. of 1/2 in. RAH-500 gum rubber hose, a 4 in. hard rubber hose, two end plugs, two wire nuts, and a 12 ft. coil cord.
Q: Is PS20K500-18C a monitored safety edge kit?
A: No. This is for a non-monitored pneumatic edge system. It should not be used as a substitute for a monitored edge where the operator requires monitored entrapment protection.
Q: What does the C mean in PS20K500-18C?
A: The C suffix identifies the coil cord version of the PS20K500-18 kit.
Q: Can this kit replace an electric sensing edge?
A: Only if the original system is being configured as a compatible pneumatic edge system. It is not a direct replacement for a standard electric contact edge or a resistor-monitored edge.
Q: What should I check before ordering PS20K500-18C?
A: Check the required 18 ft. length, 1/2 in. hose size, coil cord requirement, switch style, and whether the operator allows a non-monitored pneumatic edge.
