R-21A Oxygen Sensor

Output Connector: 3 pin Molex
Output Voltage: 9 - 14 mV
Input Connection: 5/8-24 UNEF American Thread

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

Recent major breakthroughs by Teledyne include the utilisation of 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.
