Overview
The Beckman Instruments A-RIK-L.25 is a precision helipot (helical potentiometer) designed for fine-resolution resistance adjustment in analog electronics. This 10-turn potentiometer delivers stable, repeatable performance in measurement instruments, control circuits, and industrial equipment.
Key Features
- 10-turn construction for precise, multi-revolution adjustment
- Nichrome wire resistance element for stability and durability
- Stainless steel shaft with insulated brass terminals
- Linearity tolerance of ±0.1% across the resistance range
- Panel bushing mounting compatible with standard instrument enclosures
- 5 watt power rating suitable for low-power analog applications
Technical Specifications
The A-RIK-L.25 series delivers the precision and reliability that made Helipot potentiometers essential components in radar systems, aircraft control instruments, and laboratory equipment. The nichrome wire element resists corrosion and temperature drift, while the multi-turn design enables users to achieve fine-grain resistance adjustments without gear reduction or counting dials.
Typical Applications
- Analog measurement instrumentation and test equipment
- Control system calibration and adjustment
- Audio equipment level adjustment
- Scientific laboratory apparatus
- Aviation and aerospace control circuits
- Vintage and legacy electronics repair or restoration
