Frequently Asked Questions

What socket bases are compatible with this Finder 40 Series relay?

The 40.31.8.230.0000 relay is compatible with Finder socket bases 95.63, 95.03, 95.P3, 95.83.3, 95.93.3, and 95.13. These bases provide different mounting options including PCB socket and 35mm DIN rail mounting configurations, allowing flexible installation in various panel and control board layouts.

What is the difference between the 12A and 10A ratings on this relay?

The relay offers dual current ratings: 12A when mounted directly to PCB and 10A when used with a socket base. The higher PCB-mounted rating is due to better heat dissipation through the PCB copper traces, while socket mounting has slightly reduced capacity due to thermal considerations through the socket connections.

Can this relay be used for both 50Hz and 60Hz power systems?

Yes, the Finder 40.31.8.230.0000 features an AC coil designed for both 50Hz and 60Hz operation at 230V, making it suitable for European (50Hz) and North American/other international (60Hz) power systems without modification.

What are the physical dimensions and pin specifications for PCB layout design?

The relay features a 3.5mm pin pitch with 5.2mm pin length and measures 12.4mm in width. These compact dimensions allow high-density PCB layouts while the standardized pin pitch ensures compatibility with common PCB design software libraries and manufacturing processes.

What temperature range can this relay operate in?

The Finder 40 Series relay operates reliably across an ambient temperature range of -40°C to +85°C, making it suitable for both indoor controlled environments and harsh industrial conditions including outdoor installations and unheated industrial facilities.
