The Raztec PROBE sensor is a compact, high current, open loop current sensor, capable of operating under high overload and ambient temperature conditions.

It is specifically designed for use in applications where small size is critical and current is to be measured economically. It mounts through a 6.5mm diameter hole in the current carrying bus bar.

This particular very high speed version of the PROBE incorporates hybrid technology to assure excellent speed of response for the fast detection of fault current transients.

This version of the sensor is optimized for linearity over the entire current range. There is also negligible hysteresis which makes current sensing over a wide dynamic range practical.

It is rated for common automotive temperature ranges with very stable performance parameters that set a new benchmark for open-loop current sensors.

The PROBE is configurable for a wide range of bus-bar sizes and current ratings.
