OPTO Couplers and Photo Couplers

Opto Coupler

Approx Price: Rs 10 / Piece(s) 
We are actively engaged in offering the high quality assortment of Opto Coupler. These products are known for their durability, high performance, and low power consumption. Our range is widely used in commercial complexes, under-construction sites and many more industries for variegated applications. It is a component that transfers electrical signals between two isolated circuits by using light. Moreover, it prevents high voltages from affecting the system receiving the signal.


  • Voltage - Isolation: 5000Vrms
  • Current Transfer Ratio (Max.)    : 600% @ 5mA
  • Current Transfer Ratio (Min): 50% @ 5mA

AT89C52 Microcontroller

Approx Price: Rs 10 / Piece(s) 
We have gained expertise in offering a quality approved range of AT89C52 Microcontroller. The microcontroller controls the counting and displays the number of persons present in the hall/room. The control logic is built around transistors, operational amplifier LM324 (IC1) and JK flip-flop (IC2). When nobody is passing through the entry/exit point, the IR beam continuously falls on phototransistor T1. Phototransistor T1 conducts and the high voltage at its emitter drives transistor T3 into saturation, which makes pin 3 of comparator N1 low and finally output pin 1 of comparator N1 is high.


  • Programmer can be connected to the PC through the serial port: COM1 to COM4
  • Supports both Parallel and SPI Programming
  • Facility is available to program the device soldered in the target hardware through SPI bus
