Features

Release AT Configurable. Ruthenium contact. 5.0 mm Glass length. Normally Open. Inert gas filled. 4 types of Lead Formations.

Benefits

Omni-polar. Does not require power for operation. Sputtered Contact. RoHS Compliant. Not ESD Sensitive.

Description

This Form A reed switch is built with a 2.25 mm diameter glass with a higher wall thickness for better glass to metal seals, and is a good solution for general purpose, high volume applications with a little shock and vibration, such as toys. The centre contact also makes it suitable for coil applications. The three Release AT ranges available cover a wide range of Release AT specific applications. A specially Sputtered contact for 230 VAC line voltage switching is also available. The cropped version is suitable for smaller plastic housings and can be soldered to cables, the SMD version is suitable for reflow on PCBs, and the vertical and horizontal mount versions are suitable for mounting on through hole PCBs.
