Description
Tokyo Cosmos (TOCOS) Industrial Potentiometer
Model: RV30YL 15S B2KΩ | Heavy-Duty Shaft Lock Type | Sealed Carbon Film Element
Product Overview
The genuine Tokyo Cosmos (TOCOS) RV30YL 15S B2KΩ Potentiometer is a heavy-duty, high-reliability industrial variable resistor engineered for panels and systems where setting drift cannot be tolerated. Featuring a 2k Ohm resistance value with a Linear (B) taper, this 30mm diameter component utilizes a highly stable carbon film element. Its defining characteristic is a robust shaft lock type configuration, which allows operators to lock the rotational shaft firmly in place once calibrated. This feature protects critical parameters against accidental human adjustments, heavy structural vibration, or panel shock in severe factory environments.
