Standard Limit Switch Box 2xNO PNP NAMUR Inductive Switch ATEX 8VDC/1mA

This limit switch box checks the end positions for pneumatic actuated quarter-turn valves. The box is mounted on top of the actuator and detects the shaft position with built-in switches. The housing and cover are made of Vestamid PA. The selector shaft and assembly bridge are made of PA6. The seals are made of EPDM and NBR, and the screws are of 1.4301 stainless steel. Suited for temperatures between -20 and +80 °C (-4 and +176 °F). The switch box is suitable for various mounting holes patterns and utilizes a NAMUR switch with an 8 VDC / 1 mA (3 mA non-damped) capacity.

Pros:

• Fits mounting hole patterns 50 x 25, 80 x 30 and 130 x 30 mm
• Shaft height adjustable from 20 to 30 mm
• Safe NAMUR switch (ATEX II 2G Ex ia IIB T6)
• Dust-tight and temporary submersible (IP67)

Cons:

• Not suitable for size '50' 'PAL' pneumatic actuators
• 'PAL' pneumatic actuators size '1' with a Namur valve may require the V2N28 spacer plate
