Crowtail – Dry-Reed Relay 2.0 is a compact reed relay with hermetically sealed contacts, providing fast and reliable switching. Used in automation systems, microelectronics, and detection systems requiring precision and durability.
The Crowtail – Dry-Reed Relay 2.0 module is a reed relay whose operation is based on magnetizing the contacts enclosed in a glass capsule by passing current through the coil. Thanks to the hermetically sealed contacts in a vacuum or gas-filled tube, the module features high durability, resistance to contamination, and fast switching speed. Its compact design and high sensitivity make the relay suitable for precise automation circuits, detection systems, and microelectronic projects.
