Series MR
Half-Inch Diameter Process Sealed Rotaries
Distinctive
Characteristics
Low profile body of MRF model accommodates space limitations
required for PCB mounting. For the MRA and MRK bushing
mount models, the range of behind panel body depths is .323”
to .669” (8.2mm to 17.0mm).
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.
G
Break-before-make contact timing with sliding contacts
in MRA and rotary contactor disk in MRF and MRK
models.
Interior housing seal and molded-in PC terminals, plus shaft
rubber o-ring on MRA and MRK and polyamide cover on MRF
model, allow cleaning after automated soldering.
MRK model meets IP67 of IEC60529 specifications (similar to NEMA 4 & 13).
