( Brand: Square D ), ( Manufacturer Part Number: 9007-CR53B2 ), ( Part Type: Switch )
The 9007-CR53B2 Square Explosion-Proof Limit Switch is a robust and reliable safety device designed for use in hazardous environments. This limit switch is specifically engineered to meet the requirements of Class I, Groups E, F, and G, Division 1 and 2, and Class II, Group E, F, and G, Division 1 locations, as per the National Electrical Code (NEC) and International Electrotechnical Commission (IEC) standards.
The 9007-CR53B2 is a square-shaped limit switch, measuring approximately 4.8 inches by 4.8 inches (122mm x 122mm), making it suitable for various applications where space is a constraint. The switch is constructed with high-quality materials, including a corrosion-resistant, powder-coated aluminum housing and a 316L stainless steel actuator, ensuring durability and long-lasting performance in harsh conditions.
The switch operates on a 12V DC power supply and features a normally open (NO) contact configuration, which means it is in the open position until actuated. When the limit is reached, the switch closes, providing a signal to the controlling system. The switch is rated for a maximum operating temperature of 158 F (70 C) and can withstand an explosion pressure of 10 psi (0.69 bar).
The 9007-CR53B2 is designed for ease of installation and maintenance. It comes with a 6-foot (1.8m) cable and a mounting bracket, allowing for flexible placement options. The switch is also IP66 rated, meaning it is dust-tight and can withstand powerful water jets from any direction, ensuring protection against ingress of water and debris.
In conclusion, the 9007-CR53B2 Square Explosion-Proof Limit Switch is an essential safety component for applications in hazardous environments. Its robust construction, reliable operation, and compliance with explosion-proof standards make it an excellent choice for industries such as oil and gas, mining, pharmaceuticals, and chemical processing.
