Littelfuse's New Ultra-Miniature 12.7mm Reed Switches

Creation Date

Recently, Littelfuse announced the launch of the MATE-12B reed switch series. These ultra-compact reed switches offer longer life and greater reliability than existing 12.7mm reed switches for millions of cycles. Their service life exceeds the requirements of automatic test equipment and electrical applications.
The MATE-12B is a normally open switch with a 12.7mm x 1.8mm (0.276" x 0.071") glass enclosure that can switch up to 200 Vdc 10W. This switch has a high insulation resistance of 1012 ohms (minimum) and a low contact resistance of less than 100 milliohms.
The MATE-12B reed switch series is ideally suited for markets that require long life and high reliability, such as automated test equipment (ATE) for power semiconductor testing, appliances, and other limit switch applications.
Key benefits and differentiators of the MATE-12B include:

High Reliability and Long Life: Extensively tested and validated for millions of operating cycles, offering significant advantages over currently available 7mm reed switches.
Design Flexibility: Ultra-compact magnet size and hermetically sealed glass housing make it suitable for more challenging environments and applications.
Save PCB space: Extremely compact dimensions and light weight help reduce the size of the final product.
Suitable for harsh environments: fully sealed and cULus compliant.

"The MATE-12B is an extension of our existing product line to help our end customers significantly improve efficiency and extend service life." Wayne Wang, global product manager at Littelfuse, said, "Minimising the risk of failure is especially important for limit switch applications such as automatic test equipment for appliances and power semiconductors."
As for availability, the MATE-12B reed switch series is available in 1,000-piece lots. Samples are available through Littelfuse authorised distributors worldwide.
