The Littelfuse Inc. MDSM-4R-12-18 is a sub-miniature, surface mount reed switch featuring a normally open (SPST-NO) contact configuration. It is capable of switching up to 200Vdc at 0.50A, with a maximum contact power rating of 10W. The switch exhibits low and stable contact resistance, typically less than 0.100 ohms, and high insulation resistance of at least 10¹⁰ ohms.
Designed for surface mounting with gull wing termination, this reed switch has a glass envelope measuring 2.28mm in diameter and 15.24mm in length. The overall dimensions are 19.30mm in length and 2.85mm in height above the board. It operates within a temperature range of -40°C to +125°C.
Key features include hermetically sealed contacts, zero operating power requirement for contact closure, and a sensitivity range of 12-18 Ampere-Turns (AT). Applications include position sensing, level sensing, industrial controls, security systems, limit switching, and office equipment.
The MDSM-4R-12-18 is specified with a typical contact capacitance of 0.2 pF, an operate time of 0.6 ms, and a release time of 0.2 ms. It is listed with RoHS3 compliance and MSL 1 rating.
