Description

The 1L-MSM-111 series Surface Reed Mount Magnetic Switches are engineered for precision sensing in various industrial and automation applications. Available in three configurations—NO (Normally Open), NC (Normally Closed), and NO/NC (Dual Output) — these switches are housed in compact ABS plastic bodies and built for high durability and long service life. Designed with surface-mount options, each switch ensures hassle-free installation using either screws or adhesive tapes. With a robust mechanical life exceeding 10 million cycles, these magnetic switches are well-suited for use in security systems, door interlocks, position sensing, and machinery safety setups.

All variants feature reliable PVC wiring with a standard 18″ length, heat- and moisture-resistant construction, and operate efficiently within a wide temperature range of -20°C to +70°C. With minimal contact resistance and a compact size (50 x 10 x 10.5 mm), the 1L-MSM-111 switches offer high performance in demanding conditions. The different core and wire colors also assist in easy identification and wiring during installation.
