Series X25 encoders are designed for use in environments stated in: UL Class I, Group C: atmospheres such as ethyl ether and ethylene; UL Class I Group D: atmospheres such as acetone, ammonia, benzene, butane, cyclopropane, ethanol, gasoline, hexane, methanol, methane, natural gas, naphtha, and propane; Class II, Groups E, F, and G: combustible metal dusts, including aluminum, magnesium, and their commercial alloys, and atmospheres containing combustible carbonaceous dusts, including carbon black, charcoal, coal, or coke dusts, and combustible dusts including four, grain, wood, plastic, and chemicals.

Series X25 are rugged, high-performance, incremental optical encoders that feature an environmentally sealed, cast aluminum housing. A stainless steel shaft and a clear anodized housing provide corrosion resistance. Electrical outputs are electronically compatible with almost all drives and PLCs. Differential line driver outputs are available for long cable runs and higher noise immunity.
