Reed sensors for use in portable medical devices
Meder Electronic
MK24 series Reed Sensors
Now offered in two Form B versions, the MK24 series Reed Sensors are suitable in applications with low power and space limitation requirements, such as in portable medical and electronic devices.
The sensors achieve a minimum life expectancy of 50 million operations at 5V, 5mA, 100Hz and measure 5 x 1.8 x 2.2.
The MK24's base reed switch is a 4mm KSK-1A04 that, it is claimed, unequivocally surpasses all other reed switches in its size class.
Though ultra miniature, the MK24 is constructed of a rugged overmoulded package containing the hermetically sealed reed switch and requires no external power to operate.
These sensors are used as a control switch or non-contact magnetic proximity sensor for counting, position, limit and liquid-level-detection applications.
Customers can choose from three surface-mount lead designs in a SPST-NO (Form A) version: lead design 1 (straight cut axial lead), lead design 2 (Gull Wing) and lead design 3 (J Lead).
The MK24 is also available in lead design 2 or 3 in a SPST-NC (Form B) version.
The normally open (Form A) version sensors come in five contact sensitivity ranges (A, B, C, D and E), while the normally closed (Form B) version is available in a B sensitivity only.
These reed sensors are RoHS compliant.
