Easily adjustable resistance values with an adjustment band! A suitable adjustable resistor for testing purposes.
The "TRH-A" is a resistor that is a successor to the "RWH-A," which allows for resistance value adjustment using an adjustment band. By securing the adjustment band to the exposed part of the resistance wire between the fixed terminals, it enables easy adjustment of the resistance value, making it suitable for testing purposes. It is also coated with a non-flammable paint and complies with RoHS, ensuring excellent safety and environmental performance. 【Features】 ■ Resistance value can be adjusted with the adjustment band ■ Suitable for testing purposes due to adjustable resistance value ■ Coated with non-flammable material ■ Replacement for RWH-A *For more details, please refer to the catalog or feel free to contact us.
