Finder has made important production modifications to the marks on PCB 34 series relays. The relay is also widely used in industrial automation, usually as a PLC interface - sold as 38 and 39 Series modular interface relays.
Reason for change: the welding process accuracy of the cover is higher.
The ultrasonic welding manufacturing process of relay cover has been changed to the latest laser welding technology. This new program requires changing the plastic used for the EMR (electromechanical relay) version cover. This change also improves the readability of basic technical data of products. In fact, all new versions of the ultra slim 34 series will be identified as EMR or SSR (solid state relay) as appropriate, with a complete product code.
This function greatly helps panel manufacturers and installers, especially when the relay in the panel must be replaced. This useful function now appears in all our plug-in relay series.
