Littelfuse MASM-14 Surface Mount Reed Switches

Littelfuse MASM-14 Surface Mount Reed Switches are close-differential, subminiature, normally open switches designed for precise and reliable operation. These switches feature a 14mm x 2.28mm diameter glass envelope and can switch up to 200VDC or 0.5A at 10W. The low hysteresis between pull-in and drop-out values ensures consistent performance. The body is made of hermetically sealed glass, and the leads are tin-plated Ni-Fe wire. These devices are used in position sensing, level sensing, security systems, industrial controls, office equipment, and home appliances.
