Pneumatic Stroke Completion Sensors
Stroke Completion Sensors (SCS) mount directly on cylinder ports
to provide an air signal when rod motion stops...even when the full
stroke length is not used. Stroke completion sensors automatically
adjust to variable strokes, replacing limit and reed switches in
clamping, holding and sequencing tasks.
Sensors work by comparing supply pressure to exhaust pressure.
Once the pressure drops on the exhaust side of the cylinder, the
sensor will emit an air signal. Stroke completion sensors are not
recommended for cylinder inching operations with pressure held
Air to electric switches convert air signals into electrical signals...
ideal for actuating solenoid power valves or other electric
components. Switches may be wired normally closed or normally
Actuator head model MPE-B may be easily mounted on any
plunger-type switch; operating range is 8 PSI (minimum) to 100
PSI (maximum) and is not adjustable to a specific pressure.
Switch models MPE-BZ and MPE-BZE are single pole double throw
(SPDT), have a 15 amp capacity for normal, low resistance electrical
circuits and are UL and CSA listed. Solder terminals accept up
In this sample circuit, sensor #1 provides an air signal when the
cylinder rod is retracted. When the four-way control valve shifts, air
flows to the cylinder , which extends. This causes sensor #1 to shut
off. The cylinder rod stops when it reaches the work piece or end of
stroke, causing sensor #2 to emit an air signal. This air signal may be
used to actuate another valve or for sequencing operations.
When using a flow control valve in conjunction with a stroke completion
sensor, place the flow control valve between the control valve
