Reed Switches combine design flexibility and precision.

Press Release Summary:




While promoting layout and design flexibility, MACD-14 reed switch series and surface-mount version MASM-14 Series have close-differential characteristics that benefit applications with limited space and strict accuracy requirements. Hermetically sealed switch contacts are not affected by harsh environments, and low close/open hysteresis provides precise switching. Switching capability is 200 Vdc at up to 10 W, and sensitivity range is 10–30 AT.

Littelfuse Extends Reed Switch Product Line with High-Precision MACD-14 and MASM-14 Series



New switches serve additional market segments requiring close-differential characteristics at a competitive price



CHICAGO – Littelfuse, Inc., the global leader in circuit protection, has released the MACD-14 and MASM-14 Series, a high-precision extension of its reed switch product line. (The MASM-14 is the surface mount version of the MACD-14.) These reed switches have close-differential characteristics that benefit customer applications with space limitations and strict requirements for accuracy. In addition, the MACD-14 and MASM-14 Series allow circuit designers to enjoy enhanced layout and design flexibility.



“The close-differential characteristics of the MACD-14 and MASM-14 Series allow us to serve new market segments that require high-precision sensing at a competitive price,” said Gwenn Gmeinder, business development manager at Littelfuse. “These switches are ideal for level and proximity sensing in water pump, brake fluid reservoir, windshield washer fluid level and small appliance applications.”



The MACD-14 and MASM-14 Series offer these key features and benefits:

Through-hole, surface-mount and custom forms provide layout and design flexibility

Hermetically sealed switch contacts are not affected by harsh environments

Close differential (low close/open hysteresis) provides precise switching  for applications with limited space

Switching capability of 200 Vdc at up to 10 Watts provides high load switching capability and flexibility in a compact package

Available sensitivity range of 10-30 AT for high-accuracy performance under all operating conditions



“As design footprints and components continue to shrink, many of our customers are challenged by the very limited travel space available for the magnet to both activate and de-activate the reed switch or sensor,” explained Gmeinder. “The close differential of the MACD-14 and MASM-14 Series allows our customers do more with less space and less budget.”



Availability

The MACD-14 reed switch and MASM-14 surface-mount reed switch are available in three different models and in minimum order quantities of 250. The MASM-14 is also available with tape and reel packaging. Sample requests can be placed through authorized Littelfuse distributors worldwide.
