The Rexroth R928028410, model WE-2SP-M12X1, is a high-quality electrical clogging indicator designed for use with hydraulic filters. This essential component monitors the differential pressure across a filter element. When the contamination level reaches a pre-set threshold, the indicator sends an electrical signal to alert operators or control systems that the filter element requires maintenance or replacement. Featuring two switching points (normally open/normally closed) and a standard M12x1 electrical connector, it ensures reliable system protection and facilitates proactive maintenance, preventing potential damage to hydraulic components and reducing downtime.
