MK25 Series Reed Sensor

The MK25 Series is a robust, intrinsically safe contactless reed sensor designed for panel mounting in hazardous or potentially explosive environments. Certified to ATEX and IECEx standards, it offers reliable switching performance in industrial safety systems, mining operations, and other high-risk applications. The MK25 Series supports SPST-NO (Form A), SPST-NC (Form B), and SPDT (Form C) contact configurations, with rated power up to 10 W, 400 VDC, and 0.5 A.

Its modular design allows for customization of internal switch types, cable lengths, and terminations. Optional button plates and emergency stop buttons can be laser-inscribed for long-lasting durability, making the MK25 ideal for rugged environments where printed labels may degrade over time.

Type of protection: II 2 G Ex mb IIC T6, II 2 D Ex tD A21 IP65 T85 °C
In accordance with: IEC/EN 60079-0, IEC/EN 60079-18, IEC/EN 61241-0, IEC/EN 61241-1
