Optical Couplers

  • Advantages and Functions of Optoelectronic CouplerAdvantages and Functions of Optoelectronic Coupler2017/12/29Optical coupler's main advantages: signal one-way transmission, input end and output end have full electrical isolation; the output signal has no influence to the input end; strong anti-interference a...
  • The Principle of the Use of Optical CouplerThe Principle of the Use of Optical Coupler2017/12/291. The allowable range of current transmission ratio (CTR) of optical coupler is 50% ~ 200%. This is because when the CTR< 50%, the leds in the optical coupling require a larger working current (IF...
  • Performance characteristics of Photoelectric CouplerPerformance characteristics of Photoelectric Coupler2017/12/291. High common mode rejection ratio (CMRR) Inside the photoelectric coupler, the coupling capacitance between the luminous tube and optical receiver is very small (less than 2pF), so common mode input...
  • Restrain Sharp Pulse and Noise Interference of Photoelectric couplerRestrain Sharp Pulse and Noise Interference of Photoelectric coupler2017/12/29The photoelectric coupler can effectively suppress the sharp pulse and all kinds of noise interference in the transmission signal, so that the signal-noise ratio in the channel can be improved greatly...
  • Relevant Categories of Photoelectric CouplersRelevant Categories of Photoelectric Couplers2017/12/29There are two types of photoelectric couplers: one is nonlinear optocouplers, the other is linear optocouplers. The current transmitting characteristic curve of nonlinear optocoupler is nonlinear, whi...
  • Advantages and Disadvantages of Optical Coupler IsolationAdvantages and Disadvantages of Optical Coupler Isolation2017/12/29The advantages of photoelectric coupler isolation are:① The duty ratio is arbitrarily adjustable;② High isolation and pressure resistance;③ Anti-interference ability is strong, the photoelectri...
  • The Manufacture about Optoelectronic CouplerThe Manufacture about Optoelectronic Coupler2017/12/29The optoelectronic coupler usually adopts DIP package or SMD package. The practical process: package the infrared LED and the silicon photosensitive triode, then form the input/output pins. This proce...
  • Introduction of OptocouplerIntroduction of Optocoupler2017/12/29Optocoupler (Optical coupling) is a new type of semiconductor "electric-optical-electric" conversion device which takes light as the medium and the input signal is coupled to the output end. In other ...
