Reed Technology Solutions Product Spotlight REED RELAYS REED SENSORS REED SWITCHES KSK-1A04 Series (4mm) Reed Switches D E SC RIP T ION KSK-1A04 Series Reed Switches are magnetically actuated, ultra- NEW! miniature, low power reed switches. Designed with flat lead • The KSK-1A04 Series offers the terminals they provide consistent smallest glass size (4mm) available at contact orientation and larger MEDER contact soldering surface in SMT applications. • Ultra-miniature size conquers space limitations allowing high density board F E A TURE S population Ultra-miniature size (4mm) Hermetically sealed • Flat lead design best solution for Dynamically tested contacts consistent contact orientation and Millions of reliable operations larger surface area for SMT soldering Five different sensitivity ranges Flat lead design-Consistent World's Smallest Reed Switch with Flat Contact Terminals! contact orientation and large soldering surface No external power required for • Available in multiple sensitivity ranges (AT) • Suitable for low power miniature operation devices Suitable for low power applications in miniature devices Our KSK-1A04 Series Reed Switches, at 4mm in glass The KSK-1A04 Reed Switches are used in size are currently the smallest reed switch offered by contactless sensors as position and limit detection Low power miniature devices MEDER electronic and the world’s smallest reed switch switches as well as level sensors. They are Position sensor with flat contact terminals. The flat contact lead design especially fitting for applications with space limitations Limit switch provides two major assembly advantages over the and low power applications in miniature devices. A P P L IC A T IO NS Contactless sensors Space limited Hand-held devices traditional round leads, which are consistent contact orientation and large soldering surface area both ideal for Cell phones Notebook computers Medical devices (i.e. hearing aids) SMT applications. These ultra-miniature reed switches are offered in five contact sensitivity (AT) ranges (A, B, C, D, & E).
