Product catalog summary

MK31 Series Reed Sensors Overview

Features: The MK31 Series Reed Sensors are designed for low power operations with centrally aligned paddles and round corners. They are available in Tape & Reel, J-Lead, and Gull Wing configurations.

Applications: These sensors are suitable for on/off control switches, position detection, sabotage switches, and other switching elements. They are used in markets such as metering, appliances, medical, security, and telecommunications.

Specifications:

Rated Power: Maximum 3 W
Switching Voltage: Maximum 30 V (DC or peak AC)
Switching Current: Maximum 0.3 A (DC or peak AC)
Carry Current: Maximum 0.5 A (DC or peak AC)
Contact Resistance: Maximum 200 mOhm at 0.5V & 50mA
Breakdown Voltage: Minimum 100 VDC (EN60255-5)
Operating Time: Maximum 0.2 ms including bounce
Release Time: Maximum 0.15 ms
Insulation Resistance: Typical 10 GOhm
Capacitance: Typical 0.1 pF at 10kHz across open switch

Housing and Lead Specifications: The housing is made of mineral-filled epoxy with a black case color. Lead designs include flat, straight leads for PCB slot mounting, flat bent SMD leads, and J-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 30 g (1/2 sine wave duration 11ms)
Vibration Resistance: Maximum 20 g
Operating Temperature: -40 to 115 °C
Storage Temperature: -55 to 115 °C
Soldering Temperature: Maximum 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.
