RM-1318 Reduced Miniature Reed Switch

The RM-1318 Reduced Miniature reed switches are designed for applications where a size restriction is present, but a higher Contact Rating and Carry Current capability is required. The Reed blades of this reed switch have good flexibility for contact closure force, and can carry up to 1.5 A. The flattened leads are useful for orienting the internal blades to face one way while soldering, welding etc., for maximum in-group sensitivity. The three different Release AT ranges, cover a wide range of Release AT specific applications. The cropped version of this Reduced 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.
