Bistable relays

Bistable relays – Energy-efficient and reliable switching

Bistable relays can be used to switch applications in a reliable and energy-saving manner. They retain their switched position if supply voltage fails, preventing loss of information on the current switching status. Bistable relays allow for two stable switch positions even when powered down. In comparison to monostable relays, just a short switching impulse of a few milliseconds is enough to switch the relay into a defined switch position. Only a low nominal power level is required. This saves energy and reduces heat generation. In addition, the relays have high vibration and shock resistance. The bistable relay OB 5623 with forcibly guided contacts was developed for special applications such as in railway and signal technology.

Bistable relay for energy-efficient design

Specialized applications need relays that maintain their switching position if supply voltage fails, thereby preventing a loss of information on the current switched state. The bistable relay OB 5623, with its unique construction, was developed for these applications. In addition, this relay stands out for its good vibration and shock resistance.

Short switching pulses of just a few milliseconds bring the relay into a defined switched position. Only a low rated power of 1.2 W (lock) and 0.7 W (unlock) is required. The holding power is 0 Watt! This saves a large amount of energy and reduces self-heating. Designing today, for tommorrow. Let the energy revolution come.

The special feature of forcibly guided contacts (DIN EN 61810-3) enables reliable detection of the contact position. These features make the OB 5623 destined for use in challenging applications. If desired, you can purchase the relay as a manually-operated version (switch position indicator). Both designs of the OB 5623 offer a temperature range of up to 75° C. They are available with contact materials silver-nickel (AgNi) or silver-nickel + hard gold plating.
