[New Product Introduction] Ultra-small overmolded reed switch solutions for space-constrained designs

Littelfuse announces the launch of the 59177 series of ultra-small overmolded reed switches, providing designers with unparalleled flexibility for space-constrained applications. With its compact design and low power consumption, the 59177 series reed switches provide a reliable solution for a variety of high-speed switching applications.

59177 Series Ultra-miniature Overmolded Reed Switch

The 59177 Series reed switches feature an ultra-small 9.0 mm x 2.5 mm x 2.4 mm (0.354" x 0.098'' x 0.094") form factor, making them the smallest overmolded reed switches in the Littelfuse portfolio. Despite its small size, this switch can handle up to 170 Vdc or 0.25 A at up to 10 W, ensuring optimal performance in demanding applications.

One of the main advantages of the 59177 series is its ability to operate without consuming any power, making it ideal for low-power applications. This feature saves energy and improves the overall efficiency of battery-powered devices. In addition, the switch's overmolded design ensures excellent resistance to mechanical shock and vibration, giving designers greater flexibility to meet the needs of mechanically challenging applications.

In addition to their small size and low power consumption, the 59177 Series reed switches offer numerous design, manufacturing and end-user advantages. The device's small form factor allows for seamless integration in space-constrained environments, and the SMD package allows standard component installation using typical pick-and-place machines. The switch is also suitable for use in wet, harsh environments, ensuring reliable performance in a variety of conditions. In addition to this, it guarantees no degradation in performance over an extended service life. The device has no leakage current in the "on" state, making it ideal for battery-powered IoT applications.

The 59177 Series Reed Switches are an important addition to Littelfuse's comprehensive product portfolio and are designed to meet the needs of a variety of markets and applications. Its flexible design makes it ideal for:

• Security and access control systems

• Measurement applications

• Battery-Powered Consumer Electronics and Wearable Devices

• factory automation

• processing equipment, and

• Proximity and limit sensing

Julius Venckus, global product manager at Littelfuse, highlighted the switch's innovative design: "The 59177 is our smallest overmolded reed switch, featuring a J-foot (lead) design. It has enhanced resistance to mechanical shock and vibration, Giving designers more flexibility to tackle mechanically challenging applications, saving valuable space on the printed circuit board.”
