MK23 SERIES REED SENSOR

Product catalog summary

Overview: The MK23 Series Reed Sensors are characterized by their miniature size, close differential, and long life expectancy. They are suitable for applications in air conditioning, gas metering, barcode scanning, security panels, and water flow gauges, among others. The sensors serve markets such as automotive, telecommunication, security, test and measurement, household, and medical sectors.

Specifications: The sensors come in various models with different magnetic sensitivities and lead designs. Key specifications include rated power, switching voltage, switching current, carry current, contact resistance, breakdown voltage, operating time, release time, insulation resistance, and capacitance. These parameters vary across different models, providing flexibility for various applications.

Dimensions and Lead Specifications: The sensors have an overall length ranging from 13.0 to 29.6 mm, with glass lengths between 7.0 and 21.0 mm. Lead designs include flat, straight leads for PCB slot mounting, flat bent SMD leads (Gull-wing), and round bent SMD leads for PCB slot mount.

Environmental Data: The sensors can withstand shock resistance up to 30 g and vibration resistance up to 20 g. They operate within a temperature range of -40 to 130°C and can be stored between -55 to 130°C. The maximum soldering temperature is 260°C for 5 seconds.

Handling & Assembly Instructions: Proper lead clamping or heat sinking techniques should be used to prevent mechanical and heat stress during soldering and welding. Mechanical shock from dropping the sensor may alter its magnetic sensitivity or damage it. Reflow soldering conditions should adhere to JEDEC norm J-STD-020D.1.

Life Test Data: The life expectancy of reed switches decreases with increased load. The datasheet provides typical numbers of operations for various load conditions across different models, indicating the durability and reliability of the sensors under specified conditions.

Note: The datasheet contains standard product specifications and may include technical inaccuracies or typographical errors. For the most current specifications and product information, contact the nearest sales office.
