MM-1018 Micro Miniature Reed Switch

This 10mm long, Form A reed switch is designed for low power, high speed switching applications, and has a cost advantage over the UM-0018 Ultra-miniature series. The flattened leads are useful for orienting the internal blades to face one way while soldering, welding etc., for maximum in-group sensitivity, and the three different Differential types available, cover a wide range of Release AT specific applications. This micro-miniature reed switch can be molded with a 0.25 mm wall around the glass capsule for use in hazardous industrial environments to withstand higher shock and vibration. This reed switch is completely Lead-free and conforms to the RoHS directive. Click to download this product data sheet as a PDF.
