Building & Home Automation Systems

Building & Home automation systems are designed to provide centralized control of various functions throughout a facility or home. These include security, such as access control and alarm systems, HVAC, lighting, outlets, entertainment systems, and appliances. These complex systems use sensor, protection and control devices to provide safe, reliable, and efficient operation.

Explore the extensive selection of Littelfuse products that can be used in certain Building & Home Automation applications.


MDSM-4R-12-18 Reed Switches

The Littelfuse MDSM-4R-12-18 Reed Switch is a sub-miniature, surface mount, normally open switch with a 15.24mm long x 2.28mm diameter (0.600" x 0.090") glass envelope. Capable of switching 200Vdc at 10W, the MDSM-4R-12-18 is available in a sensitivity range of 12-38 AT. High insulation resistance of 1010 ohms minimum and contact resistance of less than 100 milliohms. Available in axial-leaded version (MDCG-4). Ideally suited for reed relays, security, metering, limit sensing, telecom and office equipment applications.
