Please be advised that Panasonic’s Semiconductor Relay (including PhotoMOS Relays / Solid State Relays) and PhotoIC Coupler products are not impacted by the recent Semiconductor business transfer announced in the press release issued on November 28, 2019.
Panasonic Commercializes A New Small Size, High Speed 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 and APS2 Series 20 Mbps PhotoIC Couplers. These new, small size, high speed Couplers with receiver circuit ICs are capable of creating isolation to protect circuits for high speed communication with a transfer rate of 20 Mbps.
Over the years, test and measurement companies have sought for a feature in relays that provides an accurate reading at low current. This is important because at very low current, there is a tendency for inaccurate measurements to occur, thus causing false readings. This feature is referred to as Thermal Electromotive Force (EMF), and is found in a few Relays.
Relay Contact Resistance
Contact resistance is a crucial electrical characteristic. The resistance between the contact terminals determines the Relay's ability to carry current. The contact resistance is subject to change during the life of the Relay. Based on lab investigations and testing, abnormal contact resistance has often been found with the following conditions:
