Motor Connections These wheels are designed to press-fit securely onto the 3mm D output shafts on many of our gearmotors, including our micro metal gearmotors and our mini plastic gearmotors. They also work with our 35:1 and 115:1 15.5D...

These plastic mounting brackets allow you to easily and securely mount the ubiquitous 10 mm × 12 mm × 26 mm metal gearhead motors first popularized by Sanyo’s 12GN series (e.g. NA1S…NA3S), such as our micro metal gearmotors. We also...

Add quadrature encoders to your micro metal gearmotors ( extended back shaft version required) with this kit that uses a magnetic disc and hall effect sensors to provide 12 counts per revolution of the motor shaft. The sensors operate...

This #2-56, pan-head screw is 1/4″ (0.25″) long. It is made from steel, is zinc-plated, and comes in packs of 25. Dimensions Length: 0.25 in General specifications Thread type: 2-56

This ball caster kit includes a black ABS housing, a 1/2" diameter plastic ball, two spacers (1/16" and 1/8" thick), and two #2 screw sets. The total height of the ball caster, 0.53", can be increased to about 0.7" using the included...

This sensor module has 8 IR LED/phototransistor pairs mounted on a 0.375" pitch, making it a great detector for a line-following robot. Pairs of LEDs are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be...

This rugged wheel is designed to fit securely on the output shafts of our micro and 15.5D metal gearmotors. These gearmotors should be mounted onto the side of the hub with the protruding teeth, as shown on the right. The output shaft...

The D24V150Fx family of step-down voltage regulators are high-current synchronous switching regulators that generate lower output voltages from input voltages as high as 40 V. These types of regulators are also known as switched-mode...

This array of IR LED/phototransistor pairs is great for precisely identifying changes in reflectance (like line detection). It operates from 2.9 V to 5.5 V and offers dimmable brightness control independent of the supply voltage. In...
