Product Description The RM065 5K Ohm Trimpot (also known as a Preset) is a miniature variable resistor designed for occasional circuit adjustments and fine-tuning. Encased in a compact RM065 package, it features a vertical mounting orientation with three pins spaced specifically for PCB and breadboard compatibility. For the engineering team at Robogears Pvt Ltd, these presets are essential for tasks like calibrating sensor thresholds, adjusting the contrast of 16x2 LCD modules, or setting the gain in analog amplifier circuits. The "502" code signifies 50 followed by two zeros, totaling 5,000 Ohms.

Key Highlights

  • Breadboard Friendly: The pin spacing is perfectly aligned for standard 2.54mm pitch breadboards, making it a "must-have" for rapid prototyping in your Pimpri workshop.

  • Compact Footprint: Its small 6.5mm circular body allows for high-density placement on PCBs without sacrificing adjustability.

  • Linear Taper: Provides a smooth, linear change in resistance as you rotate the dial, ensuring predictable calibration.

  • Durable Carbon Film: Built with a high-quality carbon resistive element that offers stability and long-term reliability for set-and-forget applications.

  • Top Adjustment Slot: Easily adjustable with a standard flat-head mini screwdriver, allowing for precise control over the output voltage or current.

Technical Specifications

  • Maximum Operating Voltage: 50V DC

  • Rotational Life: 200 Cycles (intended for calibration, not frequent user interaction)

  • Rotational Angle: 200° $\pm$ 20°

  • Operating Temperature: -10°C to +70°C

  • Resistive Material: Carbon Film

Prototyping & Installation Tip

Using as a Voltage Divider: To use this as a variable voltage source for an Arduino or ESP32 analog pin:

  1. Connect Pin 1 (one of the outer pins) to VCC (5V or 3.3V).

  2. Connect Pin 3 (the other outer pin) to GND.

  3. Connect Pin 2 (the center/wiper pin) to your Analog Input Pin. As you turn the dial, the voltage at the center pin will vary linearly between 0V and VCC.

Calibration Note: Presets are designed for "set-and-forget" calibration. If your project requires the user to adjust the resistance frequently (like a volume knob), I recommend using a Panel-Mount Potentiometer (WH148) instead, as it is built for thousands of rotations.
