Robotics

Robotics is an industry that uses rotary encoders to tell the robot controller where each axis arm is positioned.  We offer to this industry many options that will work for several applications, the most popular encoder series used in the robotics industry are as follows:

R20

R Series

Shaft encoders are designed for direct coupling to a device shaft. They generate specific output pulses for each revolution of the shaft. To adapt or adjust to angular and rotational misalignment between two shafts flexible shaft couplings are reccomended. Direct mounting is not recommended and may reduce bearing life. The R20 incorporates heavy duty bearings that can be used in driving a timing shaft and/or pulley system.

HS

HS Series

Hollow shaft encoders are designed with either a through-bored shaft or a blind-bored shaft, and intended to mount directly onto a motor or other shaft. This eliminates the need for a shaft to shaft coupling and mounting adapter resulting in both space and cost savings. The encoder "floats" on the motor shaft. A tether or flexible mounting bracket prevents the encoder from turning, yet accommodates for shaft-to-shaft misalignment.

RH

RH or R Series "Wheeled"

Wheeled incremental encoders use precision measuring wheel(s) to directly measure the movement of a conveyor belt, or a web of material. Wheeled encoders vs shaft encoders can more accurately track the conveyor belt or other materials. Two problems with shaft encoders in this application are: (1) slippage of the conveyor belt on the roller, and (2) inaccuracy of roller diameters. Both of these contribute to inaccuracies that reduce the overall efficiency of a material handling sortation system or precision measuring system. Wheeled encoders ride directly on the moving material, use a wheel tread having a high coefficient of friction, and have a very low starting torque resulting in virtually no slippage of the wheels on the belt. In addition, the wheels are precision ground with exacting tolerances, versus a roller which has a much larger tolerance and its circumference seldom translates into an integral number of encoder pulses per unit of linear movement.

RL

RL Series

The model RL rotary shaft encoder is a General Purpose / Heavy Duty Encoder. This encoder is ideal for Heavy Duty applications where a face mounted encoder is needed. The enclosure is 3” in diameter with a ¼” thick housing.

RS

RS or HRS Series

The model RS and HRS is an optical encoder with standard 2¼” cube shaped housing that is electrically interchangeable with most cube style encoders on the market. It is designed to mount directly on an existing shaft. A flexible mounting bracket or other type of tether allows the encoder to float on the shaft without rotating. The number of pulses per revolution is determined by setting configuration switches accessible through an access port near the connector.
