The parker pneumatic sensor fittings has a unique sensor that detects the pressure drop when a cylinder reaches the end of its stroke. They produce a pneumatic or electric output signal when the pressure drop in the exhaust chamber of the cylinder goes below their back pressure threshold.
Features/Benefits:
- Easy-to-Use
• Suited to changes of series: no adjustment to position detectors is necessary
- With Pneumatic Output
• Totally pneumatic installation • 2 possible installations: Supplied with permanent pressure (P1): produces a pneumatic signal when the back pressure threshold is reached Supplied from the control valve-cylinder circuit on the opposite side: no unexpected pneumatic signal (S) can appear during pressurisation due to the actuating pressure which supplies the sensor fitting (P1)
- With Electrical Output
• Combined electrical and pneumatic installation • Installation with continuous electrical supply only (BU) • Guarantees an electrical signal when the back pressure threshold is reached
• Fluids: Compressed air • Materials: brass, technical polymer, NBR, silicone free • Pressure: 3 to 8 bar • Temperature: -15°C to +60°C • Back pressure: 0.85 to 1 bar • Switching time: Model 7818: 3ms
