Littelfuse 59177 Ultra-Miniature Overmolded Reed Switches
Littelfuse 59177 Ultra-Miniature Overmolded Reed Switches can switch 170VDC or 0.25A at up to 10W with no standby power requirement. These switches are available in select sensitivities (operating distances) and are made of thermoset overmold material for added robustness. Littelfuse 59177 reed switches are designed with hermetically sealed, magnetically operated contacts and operate through non-ferrous materials such as wood, plastic, or aluminum. The switches feature a 175VDC minimum breakdown voltage, 0.30pF typical contact capacitance, and a -40°C to +125°C operating temperature range.
The 59177 reed switches are ideal for pick and place and are solder reflow compliant to IPC-A-610 standards. The 59177 reed switches come in tape and reel packaging and measure 9.0mm x 2.5mm x 2.4mm. Typical applications include security and access control, metering, factory automation, process equipment, small appliances, and proximity and limit sensing.
