Backplane Connectors - Accessories: 5223985-5

Backplane connectors are accessories that are used to join two or more devices that are connected to each other through a common backplane. The 5223985-5 backplane connector is an example of a high quality, low profile, low power, and high-speed connector. It is designed to support both 3.3 V and 5 V applications and also supports 2.5 Gbps data rates.

Overview

The 5223985-5 backplane connector is a 50-way, 2-row, right-angle through-hole male connector designed for connecting two or more motherboard-mounted devices. It conforms to the MIL-C-22992/22-1 MIL-STD-1553 specification and is qualified to UL 1977 and CSA 22.2. The connector is made from a high-grade thermoplastic and is offered with a black over-molding. The overall dimensions of the connector are 6.65 mm x 0.5 mm and its operating temperature range is -55°C to +105°C.

Application Fields

The 5223985-5 backplane connector is primarily used in aerospace, automotive, computer, telecom, and military applications. It is also used in medical, networking, industrial control, and instrumentation equipment. This connector is particularly useful in applications where high pin count, low-profile spacing, and cost savings are required.

Working Principle

The 5223985-5 backplane connector is designed to provide a low-profile, high-speed interface between board-mounted devices. It consists of two rows of pins that are soldered directly to two grounds or power and one logic ground. The pins then get connected to the circuit board by soldering or wire-wrapping. Each row of pins includes twenty-four signals and one ground or power line. The signals are connected to external hardware by a 24-way ribbon cable. The connector has a low profile design so that the connectors can be mounted directly to the board without the need for mounting hardware.

Performance Specifications

The 5223985-5 backplane connector is designed to provide reliable connections in highly demanding environments. It has an operating temperature range of -55°C to +105°C and a high-level current rating of 1.6 Amps at 70°C (maximum). The contact retention and mechanical durability are rated at >700 insertion cycles and >300 manipulations. The contact resistance is rated at 20 mΩ maximum and the insulation resistance at 1000 MΩ minimum.

Conclusion

The 5223985-5 backplane connector is an excellent choice for applications where high pin count, low-profile spacing, and cost savings are required. It is designed to provide reliable connections in highly demanding environments and conforms to the MIL-C-22992/22-1 specification. The connector is offered with a black over-molding and has an operating temperature range of -55°C to +105°C. It also has a high-level current rating of 1.6 Amps at 70°C, contact retention and mechanical durability of >700 insertion cycles and >300 manipulations, and contact resistance of 20 mΩ maximum.
