A non-contact surface mounted reed sensor with a base reed switch (4mm KSK-1A04) achieving a minimum life expectancy of 50 million operations at 5V, 5mA, 100Hz, while measuring just 5mm x 1.8mm x 2.2mm, the MK24 series additionally offers both normally open (NO) and normally closed (NC) switch options. Having both types of switch available means a much wider variety of applications is possible for those specifying this tiny but powerful sensor.
The normally open version is available with three lead options: straight cut axial, gull wing and J lead with the normally closed option available with gull wing and J lead designs. All these reed sensors are RoHS compliant.
Though ultra miniature, the MK24 is constructed of a rugged overmoulded package containing the hermetically sealed reed switch. Additionally, the reed switch is supplied in tape and reel packaging, making it suitable for automatic pick and place.
As well as their high performance and ultra miniature size, the MK24s require no external power to operate, making them especially suitable in applications with low power and space limitation requirements such as in portable medical and electronic devices.
These sensors are used as control switches or non-contact magnetic proximity sensors for counting, position, limit and liquid level detection applications.
