The new Beckhoff EQxxxx EtherCAT Box I/O series in durable V2A stainless steel housings are rated at protection class 
IP 69K. As a result, these rugged I/O modules are designed for use directly on machines in application areas with demanding hygienic requirements, such as in the food, packaging, chemical and pharmaceutical industries. In addition to excellent protection in harsh production environments, a wide range of digital and analog units in this new product series cover numerous I/O signal requirements. Processes and signals in hygienically critical areas can be measured, evaluated and controlled directly on the machine. The EQ series EtherCAT Box meets all “hygienic design” requirements and thrives outside of electrical cabinets: the housing and all screw connections are made entirely of stainless steel. The screws are fitted flush without grime-collecting contours. These distributed I/O boxes are mounted to the machine or equipment by means of mounting brackets. This avoids unwanted cavities and joints in which dirt can settle while ensuring proper cleaning procedures.
