Product catalog summary

MK18 Series Reed Sensors Overview
The MK18 Series Reed Sensors are cylindrical sensors available with various cable terminations and lengths, suitable for applications such as door and window contacts, water level detection with magnetic floats, and position sensing. These sensors are used in markets including appliances, industrial, and security.

Specifications

Contact Data: Rated power is 10 W, with a maximum switching voltage of 200 V and a maximum switching current of 0.4 A. The contact resistance is 150 mOhm, and the breakdown voltage is 0.23 kVDC.
Housing and Lead: The housing is made of PBT glass fiber reinforced material, with a black case color and polyurethane sealing compound. The cable is a flat PVC type with a cross-section of 2 x 0.14 mm².
Environmental Data: The sensors can withstand a shock resistance of 50 g and a vibration resistance of 20 g. The operating temperature ranges from -30 to 70 °C when the cable is not moved, and -5 to 70 °C when moved.

Handling & Assembly Instructions

Maximum torque for screws is 1Nm.
Cable bending-radius should be diameter x 15, with a minimum bending distance to housing of 5mm.
Avoid using magnetically inductive screws and ensure a series resistor is used for cable lengths over 5m.

Glossary

Contact Form: Form A (Normally Open), Form B (Normally Closed), and Form C (Changeover).
Magnetic Sensitivity: Ranges from 05-10 AT to 35-40 AT.

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