It features a side rotary roller actuator that provides consistent snap action response with high mechanical endurance. The switch’s double-pole, double-throw (DPDT) configuration with 2NO/2NC contacts supports flexible circuit control in both AC and DC systems. Constructed from rugged, explosion-proof materials and sealed to an IP67 rating, it ensures safe operation in environments exposed to gas, dust, or moisture. The 3/4" NPT conduit entry and screw terminal connections simplify installation and maintenance in heavy-duty field applications. Key Features: Explosion-Proof Design: Certified for hazardous locations, ensuring safe operation in environments with flammable gases or dust. DPDT Contact Configuration: Provides two normally open and two normally closed contacts for versatile circuit control options. Side Rotary Roller Actuator: Enables precise mechanical actuation for applications requiring smooth, repeatable switching. Snap Action Mechanism: Delivers rapid switching performance with minimal contact bounce and extended electrical life. High Electrical Ratings: Handles up to 10A at 120–600V AC and 800mA at 120V DC for both control and power circuits. IP67 Environmental Protection: Fully dust-tight and waterproof for reliable use in harsh or outdoor conditions. Durable Metal Construction: Heavy-duty body ensures strength, corrosion resistance, and long service life. Wide Mechanical Travel Range: Offers 15° pretravel, 7° differential, and 60° overtravel for flexible application design. The BXM4N-1A delivers the reliability and precision required for position detection, safety interlocking, and control applications in hazardous industrial environments.
