Specification

SEODescription

The MK 3/12 terminal blocks by MK Electric are DIN rail-mounted connectors designed for secure and flexible electrical connections in industrial applications. These DIN rail 3/12 terminals support up to 12 modules per unit, enabling direct integration with control systems, sensors, and relays. They feature 3 input and 12 output channels, accommodating a voltage range of 24-240V AC/DC and operating temperatures from -20°C to +70°C. Ideal for automation, energy management, and machinery, MK Electric terminal connectors offer high durability and simplified wiring with tool-free clamping. While their modular design enhances scalability, the lack of integrated communication interfaces may require additional adapters for protocols like RS-485. Compact and reliable, they excel in harsh environments with robust DIN rail mounting.
