Frequently Asked Questions

What socket bases are compatible with the Finder 40.52.7.024.0000 relay?

This relay is compatible with Finder socket bases 95.65, 95.05, 95.55, 95.P5, 95.85.3, 95.95.3, and 95.15. These bases provide options for PCB mounting, panel mounting, and 35mm DIN rail installation, offering flexibility for different application requirements.

What is the difference between standard and sensitive DC coils in Finder relays?

The sensitive DC coil in this 40.52.7.024.0000 model operates at lower power consumption compared to standard coils, making it ideal for battery-powered applications and systems where energy efficiency is important. Sensitive coils also generate less heat and provide faster response times, essential for precision control applications.

Can this 8A relay handle both resistive and inductive loads?

Yes, the 8A rating applies to resistive loads at 250V AC. For inductive loads such as motors or solenoids, the switching capacity will be lower due to the higher inrush currents and back-EMF. The AgNi contact material provides good performance with both load types, though specific derating should be applied based on your application requirements.

What are the physical dimensions and how much panel space does this relay require?

The relay measures 12.4mm in width with 5mm pin pitch and 5.2mm pin length. The compact design allows multiple relays to be mounted closely together on PCBs or in control panels, making it ideal for applications where space is at a premium whilst still providing 8A switching capability.

Is this Finder relay suitable for safety-critical applications?

This relay features 2CO (DPDT) contacts which provide positive contact indication and can be configured for safety applications requiring forced-guided contacts. The wide operating temperature range of -40°C to +85°C and robust construction make it suitable for industrial safety systems, though specific safety certifications should be verified against your application requirements.
