FAQ

Question?
What is the advantage of the gold-plated contacts on the 52102?

Answer: Gold plating prevents oxidation and ensures reliable switching of low-level signals and currents, which significantly improves long-term contact reliability, especially in low-power circuits.

Question?
Can this MIRO 6.2 relay be used in both AC and DC output circuits?

Answer: Yes, the contacts are rated for a maximum of 250 V AC/DC, making it versatile for switching both AC and DC loads up to the specified current limits.

Question?
What is the typical mechanical and electrical lifespan of this relay?

Answer: While specific values depend on the load, Murrelektronik relays are designed for high durability. Mechanical life is typically in the millions of cycles, while electrical life is dependent on the switched load but is generally rated for over 100,000 cycles at nominal load.
