Cosmo ( Photo Couplers )

We are Manufacturer, Supplier and Exporter of our product range. Our setup is situated in Pune, Maharashtra, India and majorly we serve our customers from all over India including metro cities like Pune, Mumbai, Bangalore, Chennai, Delhi, Hyderabad.

The basic function of a Photo Coupler is that it ensures total electronic isolation, including potential isolation (as in the case of transformer) in an electrical circuit.

SSR MOSFET OUTPUT

These SSR MOSFET output are used mainly to control the switch of output pole connection, which provides normally open 1A, normally close 1B, 2A,2B, normally open and normally close 1C and 1 photo coupler+1 MOS connectors. The various types of SSR MOSFET output we offer are

• Normal Close Type
• Normal Open / low Current & ON Resistance Type
• Normal Close + Normal Open Type
• Normal Open Type

The salient features are as follow :

• High voltage
• Low impedance
• Compact package
• Ant vibration contactor-less or multiple connector combination and quick response to high frequency

REED RELAYS

Our reed relays are a mechanical switch operation which controls output pole connection. The contactors may include 1A, 1B, 1C, 2A, or 2C. The main features are as follow :

• Integrated mounting packing
• Compact resistant to high voltage
• Long usable life and high isolation

The areas where these can be applied are computer peripheral, telecom, instrument, security and automation equipment. The various types we offer are as follow :

PHOTO INTERRUPTER

We offer KW Series photo interrupter which consists of a high radiant power GaAs infrared LED and a Si photo transistor. This photo interrupter is housed in a short lead package and is ideal for automatic mounting. The specifications are as follow :
