Lift cylinder with sensing valve ® Action description (Explanation about sensing and air sensing chart) Action confirmation can be conducted by detecting differential pressure with the air catch sensor connected to the push-end detecting port and pull-end detecting port. Sensing valve • Air catch sensor is required in order to conduct the action confirmation. Sensing can be done by the air catch sensor with small air flow (recommended models are in the chart below). Recommended operating air pressure : 0.2MPa Recommended air catch sensor • In order to carry out stabilized detection, the...

Sectional structure Action description Performance curve External dimensions Accessories Number directly connected to clamp: 1 1. This sensing chart shows the relationship between the stroke and detection circuit air pressure. 2. The detection pressure varies depending on the number of cylinders connected per circuit. Sensing pressure declines as the number of connected cylinders increases. (Maximum number of cylinders connected: 4) 3. The features may vary as per the air circuit structure. Please contact us for details. 4. Sensing symbol [R] detects only push end and Q] detects only pull...
