Tubular 4ps 08002325 Rev.2 01900201-647.2 Infrared Tap Sensor

Summary

Tubular 4ps 08002325 Rev.2 01900201-647.2 Infrared Tap Sensor

The Stern Tubular 4ps 08002325 Rev.2 01900201-647.2 is an infrared tap sensor assembly for Stern Tubular electronic tap installations. It is used in the sensor-controlled part of the tap system where hand detection activates the electronic control and solenoid-operated water flow.

This part should be matched against the installed Stern Tubular sensor and the printed markings on the removed component before ordering. The key identifiers to check are 08002325, Rev.2 and 01900201-647.2.

Technical Details

• Stern Tubular electronic taps use infrared sensing to detect the user's hands and trigger solenoid-controlled water flow.
• Stern Tubular documentation states a sensor range adjustment from 35 mm to 300 mm depending on installation and setting.
• Stern Tubular documentation states an operating pressure range of 0.5 bar to 8.0 bar / 7 PSI to 116 PSI.
• Power arrangement depends on the tap version, with documented Tubular versions using battery or 9V transformer arrangements.

Before You Order Checks

• Match the printed code 08002325 to the part removed from the tap.
• Match the revision Rev.2 before ordering.
• Match the printed board/reference code 01900201-647.2 before ordering.
• Check the connector shape, cable routing and installed tap power version because other Stern Tubular sensor kits and revisions exist.

Troubleshooting Notes

• Symptom: no water from the tap. Likely Cause: sensor range, low battery, security mode, reflection or solenoid/diaphragm obstruction. Solution: check power, clear obstructions, adjust sensor range and service the solenoid/diaphragm as required.
• Symptom: water flow does not stop. Likely Cause: dirty or covered sensor, reflection, diaphragm debris or disconnected connectors. Solution: clean the sensor area, remove reflective interference, check connectors and service the diaphragm.
• Symptom: reduced flow. Likely Cause: blocked filter or aerator. Solution: remove, clean and reinstall the affected filter or aerator.
