Magnetic Non-contact Switches MN Series

Product Overview

The MN series magnetic non-contact switches are designed to provide reliable monitoring of actuator doors through magnetic detection technology. These switches are versatile in installation, allowing for vertical or horizontal placement, as well as mounting from either side of the door. The robust construction and IP67 protection rating ensure these switches are durable and suitable for a wide range of industrial applications.

Key Features

• Non-powered Magnetic Detection: The MN series switches operate using a non-powered magnetic detection method, making them highly reliable for door monitoring applications.
• Versatile Wiring Options: Available in two wiring configurations—Cable type and Cable connector type—offering flexibility in installation based on specific needs.
• Flexible Installation: These switches can be installed on doors that move back and forth or right and left, with options for mounting from both sides.
• Durable Construction: Built to last with an IP67 protection structure, these switches are resistant to dust and water, ensuring longevity even in harsh environments.
• Long Life Expectancy: The switches are engineered to operate over 1 billion times under low load conditions, providing long-term reliability.
• High Vibration and Shock Resistance: Designed to withstand significant vibration and shock, making them ideal for industrial settings.
