Shaft Position Monitoring Sensor BBHME56 (replacement for 2AV54, 2AV16A, 2AV51A, 2AV56, 2AV63, CYHME56) is designed to work in the conditions of automobile environment. The device is produced in compliance with the international standard and features: modern design, accurateness, endurance, narrow temperature drifting, smooth and clean output curve as well as non instantaneous dithering.

It is applicable to engines with electrronic ejection. The main applications are in automobile industry, i.e. as a breakerless trigger in electronic systems, in control engineering, especially 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 similar products such as 2AV54, 2AV16A, 2AV51A, 2AV56, 2AV63, and CYHME56. 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.
