The parameters and performance indexes of the sensor of the optical coupling relay RF

　　Mechanical and physical parameter requirements:

　　Ensure the use of the product installation size, weight, sealing, lead pin strength and weldability of the sensor, parameters, performance indicators, etc. Including: contact pressure, contact gap, contact tracking, resetting reed pressure, armature motion, nail height and other mechanical parameters.

　　Electrical parameter requirements:

　　Ensure that the relay RF sensor under the specified conditions of use, reliable and normal operation, accurate reaction and speed signal. Including: winding resistance, contact electrical resistance, suction current (voltage), rated working current (voltage), release current (voltage), rated contact load photocoupling relay RF sensor, parameters, performance indicators, insulation resistance, electrical parameters such as strength.

　　Time parameter requirements:

　　In the control circuit, the requirements of the relay RF sensor pulling and releasing time, as well as the time parameters such as armature conversion, contact jitter and pulse distortion are often put forward.

　　Environmental adaptability requirements:

　　According to the use environment of the relay RF sensor, in order to ensure reliable work, the environmental adaptability items are: temperature (limit high and low temperature, temperature cycle, temperature shock, low temperature storage, etc.), humidity resistance (normal temperature and high humidity, high temperature and high humidity), low pressure resistance, vibration stability and vibration strength, impact stability and impact strength, constant acceleration.

　　In special circumstances, there are salt spray resistance, optical lotus relay RF sensor, parameters, performance indicators anti-mold, radiation resistance, transportation, storage and other items.

　　Life and failure rate index requirements:

　　Under the specified test environmental conditions and contact load, the number of failures of the relay RF sensor should not exceed the requirements specified in the product within the specified number of operations. The error referred to here refers to the bonding phenomenon of the relay RF sensor when the contact is disconnected during the operation process, so that the contact pressure drop of the photoelectric relay RF sensor, parameters, and performance indicators exceeds the specified level when the contact is closed.

　　relay RF sensors with reliability index requirements have specified inefficiency index grade requirements.

　　Safety specifications:

　　In order to prevent electric shock and fire, the product must meet the safety regulations of the relevant countries, such as the Great Wall of China, UL of the United States, CSA of Canada, VDE of Germany, TUV, etc.
