Half-Inch Diameter Process Sealed Rotaries Series MR Distinctive Characteristics Low profile body of MRF model accommodates space limitations required for PCB mounting. Behind panel body depths ranging from .323” to .669” (8.2mm to 17.0mm) for MRA and MRK bushing mount models. Positive detent mechanism for distinct feel and audible feedback. Metal bushing and housing construction increases durability. Adjustable stopper plate allows 2–12 position settings. High contact reliability achieved by the self-cleaning contact mechanism. Break-before-make contact timing with sliding contacts in MRA and rotary contactor disk in MRF and MRK models.
