jb Digital Knob Series – Multi-Turn Control, Visible Display, and Mounting Flexibility
In the design of professional control systems, adjustment components must offer both mechanical reliability and specification clarity. The jb Digital Knob Series is engineered to meet this standard by offering multiple configurations in turn range, numeric display, diameter, and shaft fit—all structured for seamless integration into a variety of control panels.
Whether you are working with compact circuit layouts or high-precision tuning modules, the jb Digital Knob Series provides engineers with the confidence to choose a fit-for-purpose solution based purely on objective design criteria.
Overview of Key Design Parameters
The following table outlines the main technical differences across the three models in the jb Digital Knob lineup:
| Specification | JBR-BP | JBR-BN | JBR-BM |
|---|---|---|---|
| Turn Range | 0 – 9 turns | 0 – 14 turns | 0 – 9 turns |
| Display Window | 3-digit numeric | 3-digit numeric | 1-digit numeric |
| Shaft Compatibility | Φ6.35mm | Φ4mm | Φ4mm |
| Outer Diameter | 46mm | 22mm | 22mm |
| Mounting Type | Screw-fix | Screw-fix | Screw-fix |

Why These Parameters Matter in Real Design Work
Turn Count Options: Matching Precision to Purpose
Multi-turn knobs are typically selected based on the level of control resolution required.
- A 14-turn knob provides high-precision modulation—ideal for settings that require fine increments.
- A 9-turn knob, while offering less granularity, is sufficient for broader-range or non-critical adjustments.
Display Readability: Inform at a Glance
The built-in numeric display removes ambiguity during field operation.
- The 3-digit display models (BP & BN) provide clear visibility of the knob’s position, essential for repeatable setups.
- The 1-digit version (BM) offers simplified feedback when only general range indication is needed.
Physical Integration: Fit the Panel, Fit the Workflow
Choosing between Φ4mm or Φ6.35mm shaft compatibility allows the knob to mate securely with a wide range of potentiometers or encoders.
Meanwhile, outer diameters of 46mm vs. 22mm allow flexibility across large-format panels or dense modular setups.
Built for Engineers – Not Just End Users
With standard screw-mount installation, durable mechanical construction, and straightforward technical documentation, the jb Digital Knob Series gives engineering teams the freedom to focus on performance without second-guessing part selection.
This series is ideal for procurement teams, OEM designers, or field engineers looking for predictable, spec-driven components they can trust in control design.
