Air Catch Sensor Series ISA For Workpiece Placement Confirmation No-contact sensor for confirming workpiece placement, with a configuration that is less affected by supply pressure change. ZSP PS ISA PSE IS ISG ZSM Easy-to-set-up LED level meter Compliant with manifolds of up to 6 stations Proper set position is steadily and easily set due to the LED level meter and setting dial. Compliant with centralized wiring and piping Free mounting position Setting dial Stable detection is available at any mounting position due to the pressure sensor. Below set position (Green) Wide adjustment range Compliant between 10 and 300 μm Stably detects 10 μm clearance The configuration is unlikely to be affected by supply pressure change due to the air pressure bridge circuit and semi-conductor pressure sensor. Dustproof and dripproof type

Series ISA Operation guideline: Design data When you design the pneumatic circuit using the air catch sensor, please refer to the data below. The detection distance of the air catch sensor is between 10 and 300 μm. However, please note that stable detection cannot be done when supply pressure or nozzle size are different. Relation between Nozzle Diameter and Detection Distance The data in the following charts are characteristics of hysteresis at the detection distance. In case accuracy is required by the settings, the design should be made so that the hysteresis will stay within the optimum...

Response Time Response time changes with detection distance and piping length. It is hardly influenced by the supply pressure and nozzle diameter (ø1.0 to ø2.0). While both graphs assume a fixed set distance with changes in the detection distance, Fig. 2 shows responses at various set values and Fig. 3 shows responses at various piping lengths. If the detection distance is equal to the set value, the response becomes quicker as the set value becomes smaller or the piping length becomes shorter. Detection nozzle: ø1.0 Operating piping: ø6 x ø4 tubing Supply pressure: 0.1 MPa Set distance:...
