Product catalog summary

MK22 Series Reed Sensors Overview

Features: The MK22 Series Reed Sensors are supplied in Tape & Reel with J-Lead design, making them excellent for low power operations.

Applications: These sensors are suitable for on/off control switches, position detection, and as switching elements in various markets including appliances, telecommunication, security, and medical sectors.

Specifications:

Contact Data: Rated power is 20 W with a maximum switching voltage of 200 V and a maximum switching current of 1.0 A.
Contact Resistance: Maximum of 150 mOhm at 0.5V & 50mA.
Breakdown Voltage: Minimum of 0.22 kVDC according to EN60255-5.
Operating and Release Time: Maximum operating time is 0.5 ms and release time is 0.1 ms.
Insulation Resistance: Typical value is 1012 Ohm.
Capacitance: Typical value is 0.3 pF at 10kHz across an open switch.

Housing and Lead Specifications:

Housing material is mineral-filled epoxy with a black case color.
Lead designs include flat, straight leads for PCB slot mounting and bent SMD leads of varying lengths.

Glossary:

Contact Forms: Form A (Normally Open), Form B (Normally Closed), and Form C (Changeover).
Magnetic Sensitivity: Ranges from 05-40 AT.

Environmental Data:

Shock resistance up to 30 g and vibration resistance up to 20 g.
Operating temperature ranges from -40 to 130 °C, with storage temperature from -50 to 130 °C.
Maximum soldering temperature is 260 °C for 5 seconds.

Handling & Assembly Instructions: Proper lead clamping or heat sinking techniques are recommended to prevent mechanical and heat stress. Mechanical shock from dropping can alter magnetic sensitivity or damage the sensor. Reflow soldering should follow JEDEC norm J-STD-020D.1.

Life Test Data: Load increases reduce the life expectancy of reed switches, with typical operations ranging from 1E+05 to 1E+10 depending on the load conditions.
