440E-L22BNST

The Allen-Bradley 440E-L22BNST is a cable pull switch. This cable pull switch was designed using stainless steel and it has a system length that measures 75 meters. This device is equipped with 2 normally closed (NC) safety contacts, as well as 2 normally open (NO) auxiliary contacts. This Allen-Bradley product has three 1/2-inch conduit entries, as well as direct opening action. This switching device is equipped with an e-stop button.

During the installation process, users must exercise caution. If the length of the installation is less than 10 meters, a tension spring at one end may be employed to keep the installation in place. However, this must be weighed carefully against the risk that the equipment poses to the operator's health and safety. Instead, if the application is situated in a region with significant daily or seasonal temperature changes, caution must be taken to set up the implementation kit and reset it as necessary under median temperature circumstances before starting the installation.

The thermal current of the Lifeline 4 series product is 10 amperes, and the current value is a minimum of 5 milliamperes at 5 volts. Stainless steel cable with a polypropylene sheath is used to construct this switching actuator element cable. It has an ingress protection grade of IP66 or IP67, and its usual operating temperature ranges from –25 degrees Celsius to +80 degrees Celsius (–13 degrees Fahrenheit to +176 degrees Fahrenheit). It has a mechanical and electrical life of roughly one million (1,000,000) operations, and its tensioning force to run position is typically 103 N (23.17 lb). Additionally, this device's tensioning force to lockout rating is typically 188 N (42.3 lb).
