Littelfuse Subminiature and Surface Mount Reed Switches Offer Extended Sensitivity Range

Littelfuse, Inc., a manufacturer of circuit protection, power control, and sensing technologies, announces the MITI-7 Series of Subminiature Reeds of Hermetically Sealed Form A (Single Pole Single Throw Normally Open or SPST-NO) Switches in a 7mm Long Glass Housing switch. The MITI-7 series has a sensitivity range of 6 AT to 20 AT, which is much larger than similarly sized solenoid switches (6 AT to 10 AT only). With new automated assembly equipment, Littelfuse is able to increase the production capacity of these small switches, helping circuit designers save space on densely populated circuit boards.


MITI-7 Subminiature Reed Switch and MISM-7 Surface Mount Reed Switch

Typical applications for MITI-7 and MISM-7 reed switches include position and velocity sensing for a wide range of markets:

home appliances

Building and Home Automation

Consumer Electronics

data center



A surface mount version of the MITI-7, MISM-7, is also available. Both can switch at 170VDC at 10W and offer high insulation resistance (at least 1012 ohms) and low contact resistance (<150 milliohms).

“The MITI-7 series is built on fully automated equipment with precise control,” said Max Shi, sensor product marketing manager at Littelfuse. “This equipment supports higher capacity and best-in-class quality standards, helping us to deliver more competitive Prices supply these reed switches to the global market.”

The MITI-7 subminiature reed switch offers the following key benefits:

The hermetically sealed switch contacts are not affected by or have any influence on their external environment.

Measuring only 7 mm x 1.8 mm, it requires minimal board space.

An excellent choice for switching microcontroller logic level loads, it is capable of switching 170VDC or 0.25A at up to 10W.
