Ultra-miniature overmoulded reed switch solution for space-constrained designs

Littelfuse, Inc. has introduced the 59177 Series ultra-miniature overmoulded reed switch. This switch presents designers with unparalleled flexibility for space-constrained applications. With its compact design and low power consumption, the series reed switch supplies a reliable solution for various high-speed switching applications.

The series reed switch supplies an ultra-miniature size of 9mm x 2.5mm x 2.4mm (0.354" x 0.098" x 0.094"), making it the smallest overmoulded reed switch in the company product portfolio. Despite its tiny footprint, this switch can handle up to 170VDC or 0.25A at up to 10W, ensuring optimal performance in demanding applications.

One of the key advantages of the series is its ability to operate without consuming any power, making it excellent for low-power applications. This feature saves energy and improves the overall efficiency of battery-powered devices. Also, the switch's overmoulded design provides excellent mechanical shock and vibration resistance, supplying designers more flexibility for mechanically challenging applications.

As well as its compact size and low power consumption, the series reed switch provides several design, manufacturing, and end-user benefits. Its low-profile design allows seamless integration within space-constrained environments, while the SMD package permits standard assembly mounting using a typical pick-and-place machine. The switch is also suited to wet and harsh environments, providing reliable performance in various conditions. Also, it guarantees no degradation in performance over the extended service life. It displays no leakage current in the 'open' state, making it an excellent choice for battery-powered IoT applications.

Its design flexibility makes it a perfect fit for security and access control systems, metering applications, battery-powered consumer electronics and wearables, factory automation, process equipment, and proximity and limit sensing.

Julius Venckus, global product manager at Littelfuse, emphasises the switch's innovative design: "The 59177 is our smallest overmoulded reed switch with J-type feet (lead) design. Its enhanced mechanical shock and vibration capability allows designers more flexibility for mechanically challenged applications, saving valuable space on the printed circuit board."
