Working Principle
The 91930-21125LF family utilizes a unique design to ensure signal integrity. The design consists of a double-sided circuit board which houses two rows of fingers that terminate the signal cables. The two rows of fingers, which are perpendicular to each other, are separated by an isolation wall. The first row of fingers form a shield that provides EMI/RFI protection. The second row of fingers is responsible for the signal transmission. This unique design isolates the signal transmission from any other noise or interference, while providing excellent signal integrity.
The shielded fingers also help to improve the overall performance of the connectors. The shielding improves both the EMI/RFI protection and the signal integrity of the connectors. The 91930-21125LF family also features a unique dielectric material which is designed specifically to reduce the effects of crosstalk. This material also reduces the effects of any external vibration or noise that may be present in the system.
The 91930-21125LF family of connectors also feature a latching mechanism, which provides a secure connection between the mating pieces. This helps to ensure that the connection remains reliable even under harsh conditions. The latching mechanism also ensures that the connectors remain in the correct position.
In conclusion, the 91930-21125LF family of rectangular connectors—arrays, edge type, mezzanine (board to board)—is a superior standalone solution for many applications due to its superior design and construction which provide high signal integrity and reliable connections. The combination of the double-sided circuit board, shielding, and latching mechanisms make the 91930-21125LF an ideal choice for a wide variety of applications.
