BBHME56
Replacement for 2AV54, 2AV16A,
2AV51A, 2AV56, 2AV63, etc.

 

It is used in industrial machinery, electronic injection, automation, and several other applications. In the automotive industry it may be used as a trigger in electronic systems, in control engineering it may be used in those areas where switches/sensors must operate maintenance free under harsh environmental conditions, e.g. RPM sensors, limit switches, position sensors, speed measurements, shaft encoders, scanning of coding disks etc.

The BBHME56 is replacement for the similar products 2AV54, 2AV16A, 2AV51A, 2AV56, 2AV63, and other manufacturers. They are compatible in electrical and mechanical properties but with different circuitry principle.

FEATURES

Contactless switch/sensor with open collector output (40mA)
Static switching/sensing
High switching/sensing frequency
Hermetically sealed with plastic
Unaffected by dirt, light and vibration
Large temperature and voltage ranges
Integrated protection of overvoltage etc.

The Hall Effect vane sensor BBHME56 is a non-contact sensor/switch, which consists of a monolithic integrated Hall Effect circuit and a special magnetic circuit hermetically sealed in a plastic package. The sensor is actuated by a soft-iron vane passing through the air gap between magnet and Hall sensor.

MEASURING PRINCIPLE

The Hall Effect vane sensor consist of a Hall IC and a permanent magnet (SmCo, NdFeB disc or block), which are hermetically sealed in plastic (see the following figures). The sensor is actuated by a soft iron vane that passes through the air gap between the magnet and Hall IC. The open collector output is conductive (low) when the vane is outside the air gap (see Fig. a)), and blocks (high) when the vane moves into the air gap (see Fig. b)). The output remains high as long as the vane positions in the air gap. This is the so called static function. The output signal shape is in this case
independent on the operating frequency.

Overvoltage is integrated in the circuit in order to protect against most of the voltage peaks occurring in automotive and industrial applications. The output stage has a Schmitt trigger characteristic. Most of electronic circuits can be driven directly thanks to the open collector output current of maximum 40mA.

MECHANICAL CHARACTERISTICS

The Hall Effect vane sensor is hermetically sealed in a special plastic package, so that it can also be used under harsh environmental conditions. The package is waterproof, resistant to vibration, gasoline, oil and salt. Two tubular rivets are incorporated in the package to mount the sensor on the carrier plate. The sensor has three leads for power supply, output and ground.
