Part number


Product name :

R-21AV Oxygen Sensor



Output Connector: 3 pin Molex
Output Voltage 9 - 13 mV
Input Connection: 5/8-24 UNEF American Thread

The response of the R-21AV sensor meets or exceeds the required time response (actual response of sensor is <6 seconds 0 to 90% O2), and the quality and reliabilty are beyond standard requirements.

The R-21AV has a special plating on the cathode resulting in a 200 times greater resistance to the effects of CO2. This increases the useful life of the sensor when used in exhaust emission testing.

Warranty: 12 months from date of invoice against defects in materials and workmanship.
