◆Features Of 0.8 mm SMT PCB Connectors Featuring Cross Technology
The BM80A series utilizes robust dual-sided contact technology to withstand vibration and shock, ensuring high reliability in harsh environments; it also offers flexible configurations regarding contact count, board-to-board spacing, orientation, and EMC shielding, providing excellent scalability.
*Receptacle Component
Detailed overview
*Twist-Lock Protective Cover
For the proper connection of the plug and receptacle
*Insert Draft Angle
Used to compensate for misalignment and tilt angles
*Fixed Welding Tab
For a secure connection to the circuit board
*Locating Pin/Positioning Post
Used to correctly position the connector on the
circuit board
*Coplanarity
For reliable welding during the manufacturing process
*Plug Parts
Detailed overview
*Unique Double-Sided Contact Structure
For secure contact in industrial environments(subject
to shock,vibration,thermal cycling, and harmful gases)
*Smooth Contact Surface
Contact between the uniform rolled surface and
the high-quality surface enables 500 mating cycles.
*Protected Contacts
Optimized contact and housing geometries can reduce contact damage.
*Signal Transmission
RF-optimized geometry ensures a data transmission rate of 16 Gbit/s.
*EMC Shielding
Dual-sided shielding ensures high electromagnetic compatibility,guaranteeing optimal signal integrity in industrial environments.
◆Flexible Board-To-Board Distance And EMC Shielding
The BM80A series supports stacking heights ranging from 6.00 mm to 20.00 mm. The minimum height is achieved via a stopper structure, while the maximum height is realized through a 1.5 mm variable mating depth,
maintaining an effective contact length of 0.8 mm to ensure connection reliability.
*The BM80A series supports a 2.3mm mating range, allowing the plug and receptacle to mate with a 1.5mm float tolerance without compromising data transmission;it accommodates PCB stacking heights from 6.00mm to 20.00mm, ensuring a perfect fit for applications without requiring full insertion to the bottom.
*Inserting to the limit stop achieves the minimum PCB spacing; at the maximum spacing,a mating depth of just 0.8 mm ensures a fast and reliable connection.
◆Electromagnetic Compatibility
As installation density increases, the risk of mutual interference rises. To ensure the interference-free operation of electrical components, shielded connectors with high electromagnetic compatibility (EMC) should be used.
A dual-shielding design ensures interference-free, high-speed transmission in industrial environments. The shielding materials are suitable for components with stringent EMC requirements; with a maximum coupling inductance of only 10 pH, the impact of electric and magnetic fields on the connector can be effectively quantified and evaluated.
*The large-area shielding design utilizes multi-point contact to reliably divert interference currents into the ground lines of the two PCBs.
*The shielding design ensures reliable contact throughout the 6–20 mm board-to-board spacing and the 2.3 mm safe mating range.
*The shielding design provides dual protection by resisting electromagnetic interference and preventing the connector itself from becoming a source of interference that could affect adjacent components.
◆Diagram Illustrating The Reduction Of The Quota Value
- ◆The dual-row contact connection system enables reliable mechanical and electrical connections; it supports a variable mating length of up to 1.5 mm, ensuring reliable mechanical and electrical connectivity.
- ◆Featuring a flexible terminal structure design, it achieves high connection stability by utilizing Jingsen Hong's proprietary configuration, which clears away foreign matter through increased terminal contact force.
- ◆Data transmission rates reach up to 16 Gbps, and the connectors offer excellent signal integrity.
- ◆It prevents mismating during surface mounting or mating and enhances the reliability of the entire contact assembly under vibration.
- ◆Reel packaging and pick-and-place trays, suitable for automated SMT processes.
- ◆Environmentally friendly products that comply with the RoHS directive and halogen-free requirements.
