MM-1018 Micro Miniature Reed Switch
This 10.0 mm long, Form A type Micro Miniature reed switch is designed for moderate power, low load applications. The fast operate time lends itself to high speed switching applications also. This Reed Switch has a cost advantage over the UM-0018 Ultra-miniature series. Leads are flattened for orienting the internal blades to face one way while soldering or welding and the three different Release AT types available, cover a wide range of Release AT specific applications. The cropped version of this Micro Miniature Reed Switch 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.
