801-ASC21X

Part number 801-ASC21X is a Bulletin 801 series roller type, 1-pole, limit switch with light duty type C contacts operated using the snap action, spring return operation. Designed and manufactured by Allen Bradley / Rockwell Automation, this limit switch’s contacts are fitted for 120 volts AC, 240 volts AC, 480 volts AC, and 600 volts AC, with corresponding current levels of 3 amperes, 1.5 amperes, 0.75 amperes, and 0.6 amperes, respectively. This limit switch is equipped with one (1) normally open (NO) contact and one (1) normally closed (NC) contact. Furthermore, its contacts are suited for a rated current of 1.1 amperes at 115 volts DC, 0.55 amperes at 230 volts DC, as well as 0.2 amperes at 550 volts DC. This device can be found in various applications and industries, such as packaging, food processing plants, transportation, and material handling. This limit switch provides large snap-through forces during operation in the required distance.

The Allen Bradley 801-ASC21X limit switch features a surface mounting option, as well as maintained lever actuators with a NEMA 600 contact rating. It also features a type 1 NEMA rating enclosure and has a variety of roller options. This device supports different replacement parts such as the X-45712 external lever, the X-70160 operating mechanism kit (roller lever), the X-58820 front moveable contact switch lever, and the X-45709 contact base station. This roller limit switch can operate at a temperature range of +32 to +104 degrees Fahrenheit, or the equivalent of 0 to 40 degrees Celsius. Furthermore, it requires a force of 37.82 Newtons in the operation of its roller lever. This limit switch has a minimum over travel rating of 40 degrees.
