These Planetary Gearboxes are nominally 32mm in diameter with permanent magnet reversible DC motors. We carry 12VDC and 24VDC motors and range from 8 to 265 RPM. Several right angle gearboxes. Several motors have encoders.
This is a DS18B20 temperature sensor in a waterproof housing with 3 meter (9.8 ft) long insulated leads. This is perfect for both internal and external temperature measurements in outdoor robotic applications.
