4027F60M, RF Power Sensor is designed for use in semiconductor processing and other precision process applications. At the calibrated frequency and power level, these sensors are capable of 1% accuracy. Intended for use with Bird 4421A Series Precision Multifunction Power Meters, these sensors provide a threefold improvement in long term unit to unit accuracy.

Connectors are required to be equipped on BOTH the INPUT and OUTPUT side of the sensor.
Bird guarantees the 4027 Series Sensors at +-1% Accuracy only with connectors the sensor is calibrated and sold with.
If you do not select connectors when placing this item in the shopping cart someone from sales will contact you to assist with connector selection and final pricing.
