Key Features

• Rugged Threaded Metal Bushing:

  Equipped with a solid metal shaft and a threaded mounting bushing, this potentiometer allows secure, tight panel installation. The threaded collar reinforces structural stability, preventing shaft wiggle and protecting internal PCB solder joints from mechanical stress during heavy use.

• Precise 300-Degree Rotational Travel:

  Featuring a wide $300^\circ \pm 10^\circ$ total rotational angle and smooth rotational torque (20 to 200 gf.cm), the device ensures fine tactile control. The predictable resistance curve allows accurate, repeatable voltage division for professional audio gear and instrumentation.

• Horizontal Right-Angle PCB Mount:

  The horizontal pin configuration is optimized for low-profile chassis layouts and right-angle board mounting. This design reduces vertical clearance requirements, enabling efficient space management in multi-layer electronic hardware designs and complex control interfaces.

• High-Power Electrical Handling:

  Rated for a robust 0.5W power capacity on linear taper B models, it safely manages higher electrical loads than standard compact potentiometers. This enhanced thermal and electrical capacity prevents track degradation under continuous operational use.

• Long Mechanical Operational Life:

  Engineered with high-grade materials and precision wiper contacts, the RD243N-H delivers dependable endurance exceeding 10,000 rotational cycles. The low rotational noise of under 100mV ensures pristine signal integrity over years of commercial service.
