Introduction

The QFS-016-04.25-L-D-PC4 is a rectangular connector from arrays, edge type, mezzanine (board to board) class of connectors. It is used to connect between two printed circuit boards or two single-row connectors. This connector is especially designed for applications where a very low profile and highly reliable connection is a must.

Application Field

QFS-016-04.25-L-D-PC4 connectors are mainly used in the areas of telecommunications equipment, wireless equipment, automotive electronics, storage and server applications and many other areas where a low profile design is essential. It features a standardized pin design, which is compatible with most other telecommunications connectors. The connector\'s small size and low profile design make it a great choice for space-constrained applications, while its high quality contacts and reliable connection also make it suitable for more stringent application requirements.

Working Principle

The QFS-016-04.25-L-D-PC4 connector is designed with a 4-pin array, edge type. When inserting the plug into the connector, it guides the pins into the correct position and then provides a reliable connection. The plastic housings of the connector are mated together to complete the electrical connection and to provide a dust-proof seal. The four pin array is held in place by a spring-loaded latch which provides secure latching, as well as a pull-out force of up to 6.3 N. The contact system consists of two rows of four contact positions for each side. One row is to provide a secure electrical connection while the other two are to provide signal and/or grounding capability. The QFS-016-04.25-L-D-PC4 connector is designed with a plated phosphor bronze contact material that is designed for maximum corrosion resistance and superior electrical performance. The contact is gold flash plated for maximum contact reliability and protection against oxidation. The contact area is gold flashed on both sides of the contact for excellent retention strength and superior electrical performance. The connector is designed with a 2mm pitch, and the overall height is only 4.25mm. This allows for a very low profile connector solution that meets the needs of even the most stringent application requirements. It also features a high retention force, low insertion force, and a secure latching system.

Summary

In conclusion, the QFS-016-04.25-L-D-PC4 is a great choice for applications where a low profile and reliable connection is key. It features a 4-pin array, edge type, and is designed with a small size and low profile design, making it perfect for space-constrained applications. The contact system consists of two rows of four contact positions, each of which provides secure electrical connection and/or grounding capability. It is also designed with a plated phosphor bronze contact material, gold flash plated for maximum contact reliability and protection against oxidation. The connector is designed with a 2mm pitch, and the overall height is only 4.25mm.
