These small, versatile sensors are best suited for guiding most types of clear and opaque webs. The SP-5 has a built-in 0.05” (1.27 mm) dead band for guiding webs that have uneven or ragged edges. The SP-11 and SP 12 are used to accurately guide all varieties of smooth edged webs. All are intrinsically safe, and can be used in hazardous areas where combustible gases are present.
Designed for use with Fife’s pneumohydraulic power units and control systems, the sensor bodies are constructed of black reinforced nylon, and the air supply and signal recovery inserts are made of natural nylon. The sensors are resistant to most solvents such as esters, ketones, alcohols, and hydrocarbons, as well as alkali and salt solutions. They are susceptible to phenols, formic acid, strong mineral agents, and strong oxidizing agents.
