Molded Ultra-Mini DYAD™ SRC CM5 DEVICES Features • Small size • SMT-compatible • Easily formed leads • Sputtered ruthenium contacts • Hermetically sealed contacts • Fast switching speed — up to 500Hz • Wide range of available magnetic sensitivities • Superior mechanical strength • Enhanced for better auto placement Applications • Security − Proximity sensing − Smoke alarms • Automotive − Level sensor − Lamp current sensor • Relays Description SRC Devices Molded Ultra-Mini DYADTM is well suited for small signal switching applications. The small size lends itself to surface mountable applications; working well on higher density PC boards. The Molded Ultra-Mini DYADTM has sputtered ruthenium contacts and an extraordinary strength achieved by a patented laser sealing of the leads. In low level or dry switching environments, switches typically exceed 1 billion operations. In addition, the molding process provides a solid plastic outer shell. This plastic shell provides superior mechanical strength, eliminates concerns over handling glass switches, and provides an ideal solution for high speed, automated assembly environments. Ordering Information A complete part number is represented by the digits to the right. For example, CM5S1030 is a MOLDED ULTRAMINI DYAD™ with a minimum operate value of 10NI and a maximum of 30NI. Refer to the switch operating specification charts for available ranges. Special ranges are available upon request. CM5 S XX XX Standard Test Coil "S" for straight switch The magnetic force (expressed in NI, AT or Ampere Turns) required to cause the reed switch contacts to close is called the pull-in or operate value. Maximum operate value Minimum operate value CM5 Surface Mount Molded Ultra-Mini DYAD Refer to operating characteristics table for complete part number.
