Overview
The Festo SPAU-P10R-F-Q4 pressure sensor (part number 8186653) is designed for precise monitoring of compressed air and inert gases in industrial automation. It measures relative pressure from 0 to 10 bar (0 to 145 psi) with an accuracy of ±1.5% FS and a repeatability of ±0.3% FS, making it suitable for applications where consistent pressure readings are critical. The sensor uses a piezoresistive measuring principle and offers a 12-bit ADC resolution for detailed process data.
IO-Link Integration and Configuration
This sensor supports IO-Link protocol version 1.1 with a Smart Sensor profile, enabling seamless integration into modern control architectures. It communicates via COM2 (38.4 kBd) and provides a 2-byte process data input that includes a 14-bit pressure measurement and 2-bit binary data channel for pressure monitoring. The minimum cycle time of 3 ms ensures timely data updates for real-time control. Configuration can be performed through IO-Link, teach-in, or via the illuminated LCD display and pushbuttons. For security, a PIN code can be set via IO-Link to prevent unauthorized changes to critical settings.
Output Flexibility and Electrical Characteristics
The SPAU-P10R-F-Q4 offers versatile output options to match various controller inputs. It features two switching outputs that are freely programmable as PNP or NPN, with N/O or N/C contacts, and a maximum output current of 100 mA. Additionally, it provides an analog output selectable among 0–10 V, 4–20 mA, or 1–5 V, with a rise time of 3 ms. The sensor operates on a DC voltage range of 20–30 V and includes reverse polarity protection on all electrical connections. The M8x1 A-coded plug (4-pin) complies with EN 61076-2-104 and supports both latching and screw-lock connections.
Installation and Environmental Suitability
Designed for front panel mounting, the sensor can be installed in any position, offering flexibility in panel layouts. It is rated IP65, making it suitable for environments with dust and water spray. The operating medium must be compressed air per ISO 8573-1:2010 [7:4:4] or inert gas, with oil lubrication permitted. Both medium and ambient temperatures range from 0°C to 50°C. The housing materials in contact with media include FPM, nickel-plated brass, NBR, and PA-reinforced components, ensuring compatibility with typical industrial gases. The sensor is RoHS-compliant and carries certifications including RCM, c UL us (Listed), CE, UKCA, and KC EMC.
Practical Benefits for Automation Engineers
For engineers integrating pressure monitoring into pneumatic systems, this sensor reduces wiring complexity by combining switching and analog outputs in one device. The IO-Link interface simplifies parameterization and enables remote diagnostics, which can shorten commissioning time. The tamper-proof PIN feature protects calibrated settings in shared production environments. With a weight of only 60 g and a compact design, it fits easily into existing control panels. The display supports multiple units (MPa, bar, psi, kPa, etc.), allowing operators to read values in their preferred scale without conversion. Overall, the Festo SPAU-P10R-F-Q4 provides a reliable, configurable solution for maintaining process stability in compressed air monitoring tasks.
