Airtac M5R Roller Lever Mechanical Valve M5R11006
Mechanically actuated · no coil, no pilot airThe AirTAC Airtac M5R Roller Lever Mechanical Valve M5R11006 is a genuine 5/2-way roller type control valve. A roller lever tripped by a passing cam, slide or carriage. Works from either direction. It is an external control, direct-acting valve - the spool is moved mechanically, so there is nothing to wire and no pilot line to plumb. Ports are PT1/8 with a 8.0 mm2 (Cv 0.45) effective area.

Sliding-column (spool) construction, so operating force is not affected by working pressure - there is no back-pressure effect. Lubrication is not required, but once the valve has been run on lubricated air it must stay on lubricated air; AirTAC suggests ISO VG32 or equivalent. The roller type control set is METAL, which gives a longer service life than the engineering-plastic heads. The exhaust outlet sits on top of the body, so a silencer fits directly.
About the M5R11006
The M5R11006 is a 5/2-way external control, direct acting valve that is thrown mechanically by a roller lever - there is no coil, no pilot port and no wiring anywhere on it. A cam, carriage or machine dog rolls onto the lever and trips the spool, and because the roller works in both travel directions it responds whichever way the machine part passes. It belongs to the M5 family of mechanical control valves, not the solenoid-operated 4V range and not the air-piloted 4A range.
This example uses the 110 body (100 Series single control) with PT1/8 ports and an 8.0 mm2 effective orifice (Cv 0.45). The roller returns to rest together with the spool, so each pass gives one full travel. The sliding-column construction means the control force is not affected by working pressure - there is no back-pressure effect, so changeover feels the same from 0 to 1.0 MPa. The exhaust outlet sits on top of the body, so a silencer screws straight in, and the metal control set on this roller version gives a more stable, longer service life than the plastic sets used on the button types.
Typical applications
Drill-head slide end-of-stroke signal
Bolt the M5R11006 to the frame of a drilling unit so the roller is tripped by a dog fixed to the slide. The 5/2 reversal reverses the feed cylinder and the spring-free mechanical trip needs no proximity sensor or cable run near the point of cut.
Pallet stop on a roller conveyor
Set the valve so a passing pallet's pusher bar rolls the lever over on arrival, switching air to a stop cylinder. The metal control set shrugs off repeated impact duty, and the top exhaust port lets you fit a silencer right at the conveyor rail.
Tail-lift platform interlock
On a truck tail-lift, a lug welded to the platform frame trips the roller at the top of travel to shift the 5/2 spool and confirm the platform is parked. No 12 V or 24 V coil is involved, so the switching point keeps working when the vehicle electrics do not.
How to choose
Before choosing the R roller, check whether you actually want the L free-return roller. The L trips in one direction only - the reverse pass invalidates by design - so it suits a valve that must switch on the return stroke alone. Pick the R when the same cam should signal the valve on both the out and back pass of the carriage. If you need more flow, step up to the 210 body with the same roller (8.0 mm2 becomes 9.0 mm2 at PT1/8, or 12.0 mm2 / Cv 0.67 at PT1/4) and match the port to your cylinder bore. The 110 body is the compact choice where panel space is tight. Respect the published reversal strokes: spool stroke 2.0-3.0 mm, roller stroke 4.6-6.8 mm. A cam that overshoots these figures will damage the valve - AirTAC states this explicitly - so design the cam ramp to bottom out inside the roller travel, not through it.
Frequently asked questions
It is a 5/2-way external control, direct acting, mechanically actuated valve with PT1/8 ports and an effective orifice of 8.0 mm2 (Cv 0.45). Operating pressure is 0-1.0 MPa (0-145 psi), proof pressure 1.5 MPa (215 psi), and the temperature range is -20 to +70 C with filtered air through a 40 um element. The body is aluminium alloy, lubrication is not required, and both body and panel mounting are supported.
AirTAC publishes a reversal stroke of 2.0-3.0 mm for the spool and 4.6-6.8 mm of travel for the roller lever. Your cam should complete the switch within these limits and stop, not continue through them - driving the lever beyond the published stroke damages the valve, and the datasheet warns of this explicitly. If a replacement roller control set is ever needed, AirTAC supplies the control sets separately as spares for the M5R110 and M5R210 (order code M3R210-P14A).
