Description RT Series Wire wound Variable Resistors - The 12 W and 500 W Vishay RT series wire wound variable resistors are designed for use in professional and industrial equipment with transients, repeated overloads, shocks, and vibrations in daily operations. Suggested attachments: control buttons and display screen. The enamel structure provides excellent reliability. The linear wire wound track conforms to the dissipation level of the tight structure and is designed for heavy-duty applications with a wide range of operating temperatures, such as repeated overloads, transient phenomena, and situations of impact and vibration. The variable resistor is attached to the installation hardware and the installation surface must be grounded. Variable resistor - toggle, slide
