PA-850 pressure transducer is a high corrosion resistance and drip-proof sensor that has IP-65 grade gauge body and provides switch output and analog output.
This manual describes the Copal PA-850 pressure transducer with built‑in amplifier. It lists the available fittings (R2, GF, G2), the pressure reference options (gauge, absolute, vacuum, compound) and the electrical interfaces (NPN or PNP open‑collector switch output and analog output). The document also details the internal structure, materials (SUS 316L, ABS+PC) and environmental ratings such as IP‑65.
Technical data such as rated pressure ranges, maximum pressure, supply voltage, output voltage, hysteresis settings and environmental limits are provided, along with wiring diagrams for both NPN and PNP output configurations. Ordering information and model number tables help identify the correct variant for a given application.

| Operating temperature range | ‑20 °C to 80 °C |
| Supply voltage | 10.8 V DC to 30 V DC |
| Consumption current (max) | 20 mA |
| Output voltage | 1 V to 5 V |
| Hysteresis | ≈1 %–15 % of set value |
| Switching capacity | 80 V DC, 100 mA |
| Dielectric strength | 800 V AC for 60 s |
| Ingress protection | IP‑65 |
The PA-850 operates from a DC supply of 10.8 V to 30 V.
Depending on the model, the rated range is 0–100 kPa (model 102), 0–350 kPa (model 352) or 0–1000 kPa (model 103).
The device provides both a switch output (NPN or PNP open‑collector) and an analog voltage output.
