Backplane connectors, also known as high-speed connectors, are designed to handle large spinning or non-continuous generating and transfer powers between modules, planar, and other devices. They are responsible for creating reliable and efficient connections between different components used in systems such as buses, test and measurement equipment, data storage, medical equipment, etc.

HM2S27PECA20N9LF, belonging to the Hard Metric Standard Series of backplane connectors, is designed to be used in high-speed and data applications. This type of backplane connector is ideal for those applications that require high reliability and robustness. It has a wide variety of sizes, shapes, and features.

Application Field

The HM2S27PECA20N9LF is a backplane connector which can either work as an interconnection between M2S (Male) and S2P (Screw) or be used to carry electrical power up to 12A. It has a large number of application fields, such as:

• Computer peripheral and other electronic equipment.
• Industrial equipment.
• High-voltage applications.
• Medical equipment.
• Test and measurement equipment.
• Data storage and communications.

Working Principle

HM2S27PECA20N9LF backplane connectors employ 9 contact terminals--6 M2S (Male) and 3 S2P (Screw). The male contacts are made of copper alloy which is gold-plated with contact resistances as low as 40mΩ. The screw contacts are made of phosphor bronze and gold-plated with contact resistances as low as 6mΩ.

The backplane connector is designed for optimal operation and signal integrity. Its screw contacts are held firmly in place so that they are not affected by the kind of vibration that can occur when used in extreme industrial environments. Thanks to its flexible modular system, it can fit diverse configurations and provide excellent EMC performance.

The stability and mechanical robustness of the HM2S27PECA20N9LF are such that the connector maintains a reliable electrical connection even after 1,000 mating cycles and 10g vibration tests. This performance can be attributed to the self-locking screws and the spring-loaded contacts used in its design.

The connector is also available in high-temp version based on miniature MIL-DTL-83513 specification, which supports operations in high temperatures up to 125ºC. As for the connector dimensions, it has an external width of 28.5 mm, a profile depth of 13.7 mm, and a pin height of 9.5 mm.

In conclusion, the HM2S27PECA20N9LF is a reliable and highly robust backplane connector which can be employed in a wide array of application fields due to its performance and resistance to extreme environmental conditions.
