Chen Yang .. Technologies Gmb H & Co. KG Hall-Effect Vane Sensor CYHME301 INTRODUCTION Chen Yang Automotive Shaft Position Monitoring Sensor CYHME301 is designed to work in the conditions of automobile environment. The device is produced in pliance 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 patible in electrical and mechanical properties but with different circuitry principle. CROSS REFERENCE (Table 1) Part Number CYHME301 Replacement HKZ101，HKZ101S，HKZ121 Features Contactless switch/sensor with open collector output (40m A) 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 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 (Sm Co, Nd Fe B 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...
