Frequently Asked Questions
What socket bases are compatible with the Finder 40.52.8.012.0000 relay?
This relay is compatible with several Finder socket bases including 95.65, 95.05, 95.55, 95.P5, 95.85.3, 95.95.3, and 95.15. These sockets offer different mounting options including PCB socket mounting and 35mm DIN rail mounting, providing flexibility for various panel configurations.
Can this relay switch both AC and DC loads up to 8A?
Yes, the 8A rating applies to both AC and DC switching applications, though the actual switching capacity may vary depending on the load type and voltage. The AgNi contact material is particularly well-suited for handling inductive loads such as motors and solenoids commonly found in industrial applications.
What is the difference between direct PCB mounting and socket mounting?
Direct PCB mounting involves soldering the relay pins directly to the circuit board, creating a permanent installation ideal for high-volume production. Socket mounting uses a separate base that allows the relay to be plugged in and easily replaced for maintenance, making it preferable for applications requiring field serviceability.
How does the 5.2mm pin length affect installation options?
The 5.2mm pin length provides sufficient engagement for reliable PCB connections while accommodating standard PCB thicknesses. This length ensures proper contact with plated through-holes and socket terminals, whilst allowing for automated insertion equipment in production environments.
What makes the Finder 40 Series different from other miniature relay ranges?
The Finder 40 Series combines compact dimensions with robust construction and wide temperature operation (-40°C to +85°C). The 5mm pin pitch and standardised socket system provide excellent compatibility, while the comprehensive range of coil voltages and contact configurations makes it suitable for diverse applications across industrial automation and control systems.
