Differences Between Bestact Relays and Others' Relays

Comparison of Breaking Time

Approx.1/8 the breaking time of metal seal contact relays
Bestact Relay: Glow Discharge Breaking
Air-Break Contact Relay: Arc Discharge Breaking
Metal Seal Contact Relay: Arc Discharge Breaking

Comparison of Electrical Life


Approx.3 times the electrical life of metal seal contact relays

The contact part of general metal seal contact relays and air break contact relays tends to experience severe wear and tear due to the arc discharge*¹ that occurs when breaking a DC inductive load. Bestact relays, on the other hand, shorten the breaking time due to breaking by glow discharge*² and have a longer service life due to less wear and tear on the contact part.
＊1 Arc discharge　　　　＊2 Glow discharge　

Comparison of Failure Rates

Appox.1/20 the failure rate of air contact relays

Bestact failure rate λ₆₀＝5×10⁻⁹/time or less
Air-Break contact failure rate λ₆₀＝1×10⁻⁷/time or less

Difference Between Bestact and General Reed Switches

The unique contact structure provides overwhelming advantages in terms of contact capacity and small size.
