Product catalog summary

MK11/B Series Reed Sensors (Brass) Overview

Features: The MK11/B Series Reed Sensors are cylindrical sensors available with various cable terminations and lengths, and come in different case sizes. They are designed for applications such as door and window contacts, safety control, and position sensing, serving markets like appliances, industrial, and security.

Specifications:

Contact Data: The sensors have different models (66, 85, 90) with varying rated power, switching voltage, and current capacities. The maximum rated power is 10W, with switching voltages up to 1000V and switching currents up to 1.0A.
Housing and Lead Specifications: The housing is made of brass with a polyurethane sealing compound. The cable is available in flat or round types, made of PVC, with cross-sections ranging from 2 x 0.14 to 3 x 0.14 mm².
Environmental Data: The sensors can withstand shock up to 50g and vibration up to 20g. 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: The document provides guidelines on torque limits for nuts based on thread size, cable bending radius, and other installation precautions to ensure optimal performance.

Glossary: Definitions for contact forms (Form A, B, C) and magnetic sensitivity levels (A to G) are provided to clarify technical terms.

Life Test Data: The document includes life test data for different load conditions, indicating that increased load reduces the life expectancy of the reed switches. Typical operations range from 1E+05 to 1E+10 depending on the load and model.
