NKK MRB24B-CB Miniature pcb process sealed rotary Datasheet

Miniature PCB Process Sealed Rotaries
Series MRB
Distinctive Characteristics
Double flatted bushing prevents rotation in panel and increases
stability.
Totally sealed construction, achieved with combination of an
interior o-ring, a seal between the frame and base, plus insert
molded terminals, prevents contact contamination and allows
automated soldering and cleaning.
Positive detent mechanism for distinct feel and audible
feedback.
Break-before-make contact timing with sliding
contact mechanism.
Metal bushing and frame/bracket provide
durability.
Panel seal, achieved with use of optional
exterior o-ring, conforms to IP67 of IEC60529
Standards.
High contact reliability achieved by the self-cleaning
contact mechanism.
.100” x .100” (2.54mm x 2.54mm) terminal spacing conforms to
standard PC board grid spacing for straight and right angle mounting.
Actual Size
Insert molded terminals lock out flux and other contaminants.

The MRB Series rotaries have not been tested for UL recognition or CSA certification.
These switches are designed for use in a low-voltage, low-current, logic-level circuit.
When used as intended in a logic-level circuit, the results do not produce hazardous energy.
