A rectangular connector is an electrical connector which typically consists of a plug-in housing and an array of pins in various configurations and arrangements. Rectangular connectors are usually either male or female, with male connectors containing pins or blades that insert into female connectors, and female connectors containing sockets to receive pins or blades. Though commonly used in a variety of applications, rectangular connectors often feature in audio, communications and navigation equipment.

The FI-RE21S-VF is a popular and widely used type of rectangular connector. It is a 21-way surface mount receptacle type header designed to operate at a temperature range of -55°C to +125°C. A high-temperature plastic material ensures reliable contact retention, while its beveled entry provides excellent EMI and EMC protection. Connectors are also designed to meet MIL-C-55302 product specification.

The FI-RE21S-VF makes for an ideal solution when it comes to a variety of applications due to its combination of features. It is often used in industries such as aerospace, military, medical, automotive, and consumer, among many others. In fact, it can be found in some of the most demanding application fields such as smart firmware update, distributed real-time system, smart robots, as well as analog/digital audio and HF/VHF communications.

The FI-RE21S-VF rectangular connector utilizes an array of 21 pins, which are arranged in a three-pin staggered format. Its signal contacts are arranged 4, 4, 4, 5 in a linear configuration with two ground contacts, providing unmatched quality for board connection reliability. Its pins are a single point contact design, and made with heat-treated beryllium copper material which ensures excellent electrical performance and a long service life.

In order to ensure reliable signal transmission, the FI-RE21S-VF utilizes additional features. Its high-temperature insulator kapton material provides exceptional EMI, EMC and board connection reliability even under harsh environmental conditions. It also has plated body solder tails, which are designed to provide better solderability and improved EMI/EMC attributes.

The FI-RE21S-VF’s working principle is quite simple. An insulating material encapsulates the internal components of the connector to ensure their environmental protection. At the contact point, there is an electrically conductive pathway which enables electric current to travel between points. When an electrical signal is passed through the signal contacts, they complete the circuit by connecting two previously unconnected points and allowing the flowing current to enable various electronic operations.

In summary, the FI-RE21S-VF Connector is an ideal choice of solution for a variety of demanding applications. Its reliable and highly advanced materials and design features make it suitable for applications in aerospace, military, medical, automotive, and consumer markets. Its 21-pin arrangement, beveled entry, plated solder tails, and single point contact design enable it to offer superior electrical performance, board connection reliability, and a long service life. Its working principle is relatively simple, where electricity passes through the conductive pathways of the signal contacts to enable a circuit connection and various operations.
