Rail Systems - General Info

Rail Assemblies

The 1-1/2" X 3" aluminum extrusion profiles include 3/8" NPSF ports at each end. One port is for air supply and the other for a plug or a pressure gauge. Rails are drilled to mount modules on center-to-center distances to your specifications. The minimum recommended spacing is 1-1/2" (38.1 mm) but is also dependent on vacuum cup diameter. RS18-10L modules will be mounted to the rail and tested by EDCO USA. Pilot port fittings, zone tubing and 3-way air solenoid pilot valves must be installed by the system integrator because of the many possible configurations.


1.) Purge Pilot Signal - M5 (10-32 UNF)
2.) Air Supply - 3/8 NPSF
3.) Vacuum On/Off - M5 (10-32 UNF)

Vacuum Sensor Option

A P10 plug can be removed from the front or side of the RS18 module to accomodate a VP-3 or VN-3 vacuum sensor.

Simple Module Alignment

Placing the Reference Face of the module on the center line of the thru hole aligns the compressed air port with the thru hole. The rail has a groove on the center line for ease of alignment.
