Frequently Asked Questions

What cable sizes can be connected to the Finder 94.04SMA socket?

The socket accommodates maximum stranded cable sizes of 1 x 4mm² for single conductor connections or 2 x 2.5mm² for dual conductor terminations. The box clamp/screw terminal design provides secure connection without requiring cable ferrules, simplifying installation and maintenance procedures.

Which Finder relay models are compatible with this socket?

The 94.04SMA socket is specifically designed for Finder 55 Series relays, particularly models 55.32 and 55.34. This ensures perfect mechanical alignment and optimal electrical contact performance when these relay types are plugged into the socket.

Can this socket be used in outdoor or extreme temperature applications?

Yes, the Finder 94.04SMA operates reliably across an ambient temperature range of -40°C to +70°C, making it suitable for harsh industrial environments and applications where temperature extremes may occur. However, ensure appropriate IP-rated enclosures are used for outdoor installations.

What is the difference between panel mounting and DIN rail mounting options?

The 94.04SMA offers dual mounting flexibility - it can be secured directly to control panels using mounting screws, or clipped onto standard 35mm DIN rail (EN 60715 compliant). DIN rail mounting enables quick installation and removal for maintenance, while panel mounting provides a more permanent fixed installation solution.

How does the 4-pole configuration benefit my control system design?

The 4-pole design provides four separate switching contacts, allowing complex control logic including simultaneous switching of multiple circuits, changeover operations, or isolation of different voltage levels within a single relay. This reduces the number of components required and simplifies wiring in sophisticated control applications.
