The Y-1002 servo can withstand a maximum side loading force on the shaft up to 22 lbs. For example, if this servo is used in a hoist, the weight applied to the shaft cannot exceed 22 lbs. If the weights exceed this, other mechanisms will have to be designed to accept greater side forces.
Two connectors are attached to the servo. The first connector, called the encoder connector, has 24 internal pins. Each pin is attached to a wire, and the wires carry the data signals from the computer controlling the servo. The second connector, called the power connector, has 9 internal pins. These 9 pins are used to carry the main power to drive the servo.
The servo has a length of 2.8 inches. If the servo has a brake attached, the length is 4.27 inches. The diameter of the case is 1.2 inches. The overall length of the shaft extending out of the case is 1 inch. The diameter of the shaft itself is .3 inches. This is very small servo, fitting inside the palm of your hand. It is very useful for miniature automation applications such as radio-controlled aircraft or miniature robots.
