Features

Release AT Configurable. Ruthenium contact. 10.0 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 10mm long, Form A type, Micro Miniature reed switch is designed for low power, high speed switching applications, and has a cost advantage over the UM-0018 Ultra-miniature series. The flattened leads are useful for orienting the internal blades to face one way while soldering, welding etc., for maximum in-group sensitivity, and the three different Release AT types available, cover a wide range of release specific applications. This micro-miniature reed switch can be molded with a 0.25 mm wall around the glass capsule for use in hazardous industrial environments to withstand higher shock and vibration. 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.
