  • Drawing of UM-0018-H Reed Switch for SMD mounting
  • Drawing of UM-0018-H Reed Switch for Horizontal mounting
  • Drawing of UM-0018-H Reed Switch for Vertical mounting

Features

7.0 mm Glass length. Ruthenium contact. 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

These highly sensitive, Form A reed switches are designed for low power, high speed switching applications. The 7 mm glass version is built for lower Contact Resistance and can switch higher loads. The flattened leads are useful for orienting all reed switches in a batch, in one way, while soldering, welding etc., for maximum in-group sensitivity. 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.
