Finder 40.52.9.004.0000 pistoke/PCB-rele, 2 vaihtokosketinta, 8 A, 4 V DC kela

The Finder 40.52.9.004.0000 is a compact plug-in/PCB relay with 2 changeover contacts rated for 8 A, driven by a 4 V DC coil. Its dual mounting capability—plug-in socket or direct PCB mounting—makes it adaptable for both industrial control panels and printed circuit board applications.

Highlights

• 2 changeover (DPDT) contacts for versatile switching
• Rated current 8 A, rated voltage 250 V AC
• Low coil voltage: 4 V DC, ideal for low-voltage control circuits
• Flux-proof (RT I) construction for protection against soldering fluxes and cleaning agents
• Wide operating temperature range: -40 to +70 °C

In daily use

This relay is suited for applications requiring reliable switching of moderate loads with a low-voltage control signal. Its plug-in design allows for quick replacement, while the PCB option supports automated assembly.
