The variation rate versus gap change is not large in such cases. 1 50 100 150 200 250 Gap (µm) • The larger the nozzle diameter is, the larger the variation rate of output versus gap change is. 1 50 100 150 200 250 Gap ( µ m ) • The smaller the nozzle length is, the larger the variation rate of output versus gap change is. 4 E8EB I/O Circuit Diagrams NPN Output Model Timing Charts Output Circuit 1,000,100 Pressure (kPa) E8EB-10C E8EB-01C Setting 0 Output ON OFF Operation Lit indicator (red) Not lit 0 Operation indicator (red) Brown Pressure Sensor main circuit White (ON/OFF) Black (linear output) Load Setting Pressure (kPa) Blue −100 E8EB-N0C2B +24 V Load 0V ON Output OFF Operation Lit indicator (red) Not lit PNP Output Model Timing Charts Output Circuit 1,000,100 Pressure (kPa) E8EB-10B E8EB-01B Setting 0 Output ON OFF Operation Lit indicator (red) Not lit Operation indicator (red) Pressure Sensor main circuit Brown +24 V White (ON/OFF) Black (linear output) 0 Load Load Pressure (kPa) E8EB-N0B2B Setting 0V Blue −100 ON Output OFF Operation Lit indicator (red) Not lit 5 E8EB Safety Precautions WARNING This product is not designed or rated for ensuring safety of persons. Do not use it for such purposes. Precautions for Correct Use Do not use the product in atmospheres or environments that exceed product ratings. ● Mounting • If the diaphragm is damaged, the Pressure Sensor will not operate properly. Do not insert a screwdriver or steel wire into the interior of the pressure-sensitive parts through the pressure port. • The pressure inlet has an R (PT) 1/8 taper screw and M5 female screw that conforms to JIS Standards. Apply sealing tape around the female taper screw so that no pressure leakage will occur. • The most-suitable wrench is 17 mm in size. • Make sure that the tightening torque of the M5 female screw is 9.8 N·m or less. ● Adjustment Pressure Setting • After the pressure is set with the pressure adjuster, cover the adjuster with the rubber bushing so that no dust or any other foreign material will penetrate into the interior of the E8EB.
