Finder 40.52.7.021.0000 Μικροσκοπικό ρελέ PCB DPDT 8A 21V DC ευαίσθητο

This Finder 40.52.7.021.0000 relay stands out with its sensitive 21 V DC coil, drawing only 0.3 W to switch 8 A loads via two changeover contacts. It is equally suited for direct PCB mounting or plug-in use with a compatible socket.

Highlights

• DPDT (2 changeover) contact configuration
• 8 A rated contact current, 250 V AC rated voltage
• Sensitive DC coil: 21 V DC, 300 mW power consumption
• Flux-proof (RT I) construction for demanding environments
• Wide operating temperature range: -40 to +85 °C

In daily use

The relay's AgNi contacts handle up to 2000 VA AC1, making it suitable for general-purpose switching in industrial controls, HVAC, and automation. Its compact miniature form factor saves space on densely packed PCBs or socket strips.
