MK30 Series Reed Sensors Overview

Features: The MK30 Series Reed Sensors are available in Tape & Reel, Axial, or Gull-Wing Lead designs, making them ideal for low power operations.

Applications: These sensors are suitable for use in on/off control switches, position detection, and as switching elements in microphones, among other applications.

Markets: The sensors are applicable in various markets including appliances, telecommunications, security, and medical sectors.

Technical Specifications:

• Contact Data: Rated power is 100 W, with a maximum switching voltage of 1000 V and a maximum switching current of 1.0 A. The carry current is capped at 2.5 A, and contact resistance is 150 mOhm.
• Breakdown Voltage: Minimum of 1.5 kVDC as per EN60255-5 standards.
• Operating and Release Time: Maximum operating time is 1.1 ms, and release time is 0.05 ms.
• Insulation Resistance: Typically 1010 Ohm.
• Capacitance: 0.5 pF at 10kHz across an open switch.

Housing and Lead Specifications: The housing is made of mineral-filled epoxy with a black case color. The lead design includes 2 flat, bent SMD leads.

Contact Forms: The sensors are available in Form A (Normally Open, SPST), Form B (Normally Closed, SPST), and Form C (Changeover, SPDT).

Environmental Data:

• Shock Resistance: Maximum of 30 g for a 1/2 sine wave duration of 11ms.
• Vibration Resistance: Maximum of 20 g.
• Operating Temperature: Ranges from -40 to 130 °C.
• Storage Temperature: Ranges from -50 to 130 °C.
• Soldering Temperature: Maximum of 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 should follow JEDEC norm J-STD-020D.1.

Life Test Data: The life expectancy of reed switches decreases with load increase. Typical operations range from 1E+05 to 1E+10 depending on the voltage and current conditions.
