Hall-Effect Vane Sensor CYHME301
INTRODUCTION
ChenYang Automotive Shaft Position Monitoring Sensor CYHME301 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 electronic 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 CYHME301 is replacement of the similar products (HKZ101, HKZ101S, HKZ121) of
SIEMENS. They are compatible in electrical and mechanical properties but with different
circuitry principle.

Integrated protection of overvoltage etc.
The Hall Effect vane sensor CYHME301 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.
