RS PRO Black Potentiometer Knob Cap for 21 mm Shaft


These RS PRO potentiometer caps are designed to cover collet knobs that mount onto potentiometer shafts. This gives you fine control of the voltage in your circuit. The caps are made of diecast, durable plastic for longevity and each one has brass brushing, which provides a secure and long-lasting connection.
You can use these potentiometer caps to protect the rotational knob of your device from shock, vibration and accidental movement. The caps are easy to fit – they simply push onto the knob so you don't need special mounting tools or hardware.
This product has a Restriction of Hazardous Substances (RoHS) certificate, so contains only minimal levels of any harmful substances. The caps have been handled and packed in accordance with electrostatic control standards ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007. These assure they're safe to use.
