PhotoIC Couplers

A Commercialized PhotoIC Coupler For High-Speed Communication Between Industrial Equipment.

Panasonic, a worldwide leader in cutting-edge electronic components, has developed and introduces the NEW APS1 Series PhotoIC Coupler that transmits light signals while allowing electrical insulation. This revolutionary new product is designed for high-speed transmission of signals between industrial equipment such as motors and PLCs.

The swift progression of the Internet-Of-Things on the factory floor, has created a growing demand for faster and higher-volume data communications between various equipment, such as PLCs and Sensors, in factories and processes. Immunity to noise generated inside and outside the equipment is also required to guard against equipment malfunction and breakdown. The demand for higher functionality, increasing compact-size and the growing number of components can cause high temperatures inside the equipment; so proven operation in high-temperature environments is also required.

This new small size, high speed PhotoIC Coupler With Receiver Circuit IC is capable of creating isolation to protect circuits for high speed communication with a transfer rate of 50 Mbps.  The APS1 Series PhotoIC Coupler also has a high noise immunity of 15 kV/µs and an isolation voltage of 3,750Vrms.  With proven performance at 105ºC maximum operation temperature, this product is ideal for industrial applications. The new APS1 Series uses a Totem Pole (TTL) output logic.
