Overview Industry/Application Specifications Related Info  

Overview / Design Principle:

Electrical outputs are electronically compatible with almost all drives and PLC’s. Differential line driver outputs are available for long cable runs (hundreds of feet) and higher noise immunity.

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 & 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 flour, grain, wood, plastic, and chemicals.

Classifications of hazardous locations are subject to the approval of the authority having jurisdiction. Refer to Article 500 of the National Electrical Code (NEC).
