Description
Tokyo Cosmos (TOCOS) Carbon Wound Potentiometer
Model: RV30YL 15S B502 | 5k Ohm | Heavy-Duty Shaft Lock Type
Product Overview
The genuine Tokyo Cosmos (TOCOS) RV30YL 15S B502 Potentiometer is a high-reliability, industrial-grade variable resistor built around a high-stability carbon wound element. Featuring a linear resistance rating of 5k Ohm (B502), this panel-mount component is engineered specifically for environmental conditions where calibration security is critical. It features a robust shaft lock mechanism that allows operators to mechanically secure the tuning shaft in position, entirely preventing accidental drift or rotation caused by intense mechanical vibrations, thermal cycling, or manual operator contact. It is ideal for long-term calibration in industrial machinery, field testing equipment, and critical power supply panels.

Key Features & Operational Benefits
- Mechanical Shaft Lock: Equipped with a robust external locknut that applies secure mechanical pressure onto the shaft collar, completely neutralizing tuning alterations caused by severe field shock.
- Premium Carbon Composition Film: Built with high-purity carbon materials to provide excellent resolution, high electrical durability, and reliable noise suppression.
- Sealed Industrial Enclosure: Designed with a sealed metal shell that prevents fine shop dust, ambient oil vapor, and workshop humidity from compromising the internal slider contacts.
- Linear Taper Performance: Type B linear tuning allows precise, uniform resistance adjustments across the full rotation of the wiper path.
