D-M9BW Applications
The SMC DM9BW is used for magnetic position detection on pneumatic cylinders in automated assembly, packaging, material handling and machine tool applications. It is suited for end-of-stroke confirmation on air cylinders, interlock and sequencing signals to a PLC, and cycle counting on high-duty production lines. Its 2-colour indicator is the key advantage: the LED shows green when the switch sits inside the proper operating range and red at the exact ON point, so a technician can set the optimum mounting position visually without trial-and-error adjustment.
