PID-A1 Photoionization Gas Sensor

PID-A1 Photoionization Gas Sensor Schematic Diagram

PID-A1 Photoionization Gas Sensor Notes:
1. Do not obstruct Ø3.5 sensing area
2. Seal between Ø6.2 and Ø9.0 (if different to atmosphere)
3. Pin out details:
    Pin 1: + V supply (See note 5)
    Pin 2: Signal output
    Pin 3: 0 V supply
4. All dimensions ±0.1mm unless otherwise stated 
5. Input voltage selector hole:
    a) When filled with solder the onboard regulator is disabled. A regulated supply of 3.0 - 3.6 V (typically 3.0 V) is then required.
    b) When not filled with solder the onboard regulator is enabled. A regulated or unregulated supply between 3.6 - 10 V is then required for IS applications, or up to 18 V for non-IS applications. These sensors will be internally regulated to 3.3V
Normally shipped with regulator disabled.
