Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors offer compelling advantages over other connector types in terms of size, cost and environmental protection. In particular, 91596-118 connectors are highly popular where both electrical performance and effective shielding are necessary. This article explores their application field and working principle.

Application Fields for 91596-118 Connectors

The 91596-118 connector is ideal in applications where limited PCB real estate is a significant factor; they provide identical appearance and size across all bus-lines – making them particularly suitable for use in high density designs. In addition, 91596-118 are also well suited for noise sensitive circuits, due to excellent shielding performance and a robust contact retention system. These connectors have been traditionally used in equipment from audio/visual equipment, to industrial control panels, and in data processing equipment.

The 91596-118 comes in both left-angle and right-angle models and has a particularly robust contact retention system, adjustable with different screws. This allows it to be used in vibration-prone environments, or when exposed to extreme temperatures and moisture. Both models have leadfree Zinc Alloy body for enhanced corrosion resistance.

Key Specifications for 91596-118 Connectors

The 91596-118 is a 2-row, pre-loaded, post-assembly connector. With a nominal current rating of 3.5A, the 91596-118 offers a range of design potential and supports a typical service life of 5000 mating cycles. It is designed for use in a variety of applications which require good reliability, and is compliant to standard footprint requirements. Another key specification of the 91596-118 is the electrical and shielding performance; it offers IP50 protection against dust, and its powerful contact spring and comprehensive connection design provide superior EMI shielding performance.

Working Principle of 91596-118 Connectors

The 91596-118 features a 2-row design which consists of a large contact element and an insulation body. This contact element is pre-loaded into the contact terminal and is held firmly in place with the adjustable screw. This contact element is designed to form a robust electrical connection with the mating pin, creating an efficient energy transmission. In addition, the body of the connector is highly conductive and is designed to provide excellent shielding performance against EMI/RFI.

When used with other 91596-118 headers, receptacles or female sockets, the highest level of secure connection is achieved. The 91596-118 is equipped with latches which lock securely, avoiding accidental disconnection or misalignment of the contact points. As a result, the connector provides a reliable connection, while also allowing for easy installation and removal.

Conclusion

The 91596-118 is a rectangular connector which offers superior performance in size limited and noise sensitive applications. It features a robust contact retention system, adjustable screws and a shielded body to provide excellent EMI/RFI protection. This connector is ideal for a range of applications, such as audio and visual equipment, industrial control panels and data processing equipment. The 91596-118 ensures secure connection, and its quick and easy installation and removal make it an ideal choice for many applications.
