HWC Micro Connectors, 2mm Pitch Connectors
Board-to-Board Connectors, Wire-to-Wire Connectors, Wire-to-Board Connectors
HWC and HW-M80 connectors are compact rectangular micro connectors with a 2 mm contact pitch. They are designed to meet the electrical and mechanical performance requirements of MIL-DTL-55302F and BS 9525 F0033. These electrical connectors are available for board-to-board, board-to-wire, and wire-to-wire connections, they carry signals and power between electronic components in aerospace, defense, and other systems exposed to vibration, shock, or limited installation space.

Features
- Low-frequency, high-frequency, and high-power contacts can be combined in the same connector. One connector can take the place of two or three separate units, reducing the number of connections in the system.
- Depending on the configuration, the connectors can use up to 40% less PCB space, reduce overall volume by up to 60%, and weigh 20% to 50% less than conventional connector arrangements.
- Spring latches and built-in locking mechanisms are available to keep the connection in place under vibration and other demanding operating conditions.
- More than 15 million standard combinations are available, with traceability throughout production. Custom versions can also be developed by changing existing standard components.
- Connector samples can be prepared quickly, and production lead times can be adjusted to meet project needs. We also offer technical support during connector selection and order preparation.
