These magnetic discs can be used with our mini plastic gearmotors (extended motor shaft versions only) as part of a quadrature encoder system that offers 12 counts per revolution . They are 2 mm thick with an outer diameter of 9.7 mm and...

These universal mounting hubs are designed to work with most 4 mm diameter shafts, including round shafts, and “D” shafts. Each of the two included hubs has four mounting holes for M3 screws (not included), letting you mount custom...

Overview Measuring 37 mm (1.46″) in diameter, these brushed DC gearmotors are the largest and most powerful we carry. They are available in a range of gear ratios from 6.3:1 to 150:1 and with 12 V or 24 V motors, and all versions are...

Overview The Light-Duty (LD) series of Glideforce linear actuators by Concentric International (formerly Iowa Export-Import) are 12V DC gearmotors that use a lead screw to move a shaft back and forth along its length. The shaft will hold...

These cylindrical brushed DC gearmotors are available in a wide range of gear ratios and with five different motors (two power levels of 6 V motors and three power levels of 12 V motors). The gearmotors all have the same 25 mm diameter...

Overview These tiny brushed DC gearmotors are available in a wide range of gear ratios—from 5:1 up to 1000:1—and with five different motors: high-power 6 V and 12 V motors with long-life carbon brushes (HPCB), and high-power (HP), medium...

Overview This compact sensor makes it possible to measure the distance of objects up to about 50 cm (20″) away using a simple digital pulse width interface (similar to a hobby servo control signal). It uses a short-range lidar module to...

Overview This compact sensor is a great way to quickly detect the presence of nearby objects. As long as the sensor is enabled, it takes continuous distance measurements and uses a single digital output to indicate if it detects an...

These versatile wheels use interchangeable collets to tightly grab a variety of different common motor shafts, including the 3mm D-shafts on our micro metal gearmotors and mini plastic gearmotors and the 4mm D-shafts on our 20D metal...

These wheels are great for robotics, custom RC vehicles, or any other project you need to get rolling. They measure 40 mm (1.57″) in diameter and are designed to press-fit securely onto D output shafts with a diameter of 3 mm. They are...
