71700-104LF Application Field and Working Principle

71700-104LF is a miniature dual-coil latching relay, which has a wide range of applications, such as industrial machinery as well as consumer, commercial, and entertainment equipment. The latching relay is designed to switch on and off with a very low current. In addition to its low power consumption, the 71700-104LF is characterized by a small size and considerable weight savings.

The 71700-104LF has two separate latching coils, one on each side of the frame. The magnetic element consists of a ferrite core, which is usually encased in an epoxy resin for additional protection. The ferrite core is connected to the frame of the relay in such a way that when current running through one of the coils generates a magnetic field, the core will become magnetized. This magnetization then has either an energizing or deenergizing effect on the contact, as explained below.

When the relay is in the off position, there is no current running through either coil. In this state, the core is not magnetized and the contacts are open. Applying a very low direct current voltage through one of the coils will magnetize the core. This will close the two contact arms, thus closing the switch and turning the relay on. When the current is reversed, the same process occurs in reverse and the contact arms open, turning the relay off.

The 71700-104LF is thus ideally suited for applications where power consumption needs to be kept to a minimum. Additionally, its small size helps to save precious space in enclosures or other tight locations. The latching relay is also relatively inexpensive compared to other types of relays, making it a cost-effective choice for engineers and hobbyists alike.

In summary, the 71700-104LF is a miniature, dual-coil latching relay that is capable of switching on and off with just a low current. It is suitable for a wide variety of applications, from industrial machinery to consumer products. Its small size and low power consumption make it an ideal choice for tight spaces and cost conscious engineers. Thanks to its robust construction, it is also reliable and durable.
