Catalog excerpts

Ultra-Precision Measurement System Linear and Rotary Encoders Linear Encoders Linear encoders provide the highest measurement accuracy possible. Since linear encoders measure distance directly, leadscrew accuracy and backlash are not a factor in the measurement system. Traditionally optical glass scale encoders were used for high accuracy direct linear measuring. Magnetic and inductive encoder alternatives today have significant advantages over glass scale technology. Inductive and magnetic encoders are more durable, use non-contact sensing, integrate better, and offer high accuracy in combination with Velmex UniSlide and BiSlide Assemblies.

Rotary Encoders Rotary encoders are a cost effective method to measure rotational distance on a leadscrew or motor shaft. Several cycles per rev (CPR) options and shaft bores are available. The resolution per rev is equal to 4x the CPR. For example: 400 CPR = 1600 increments of resolution per revolution. ENCODER PRODUCTS (EPC) Rotary Encoder The EPC differential encoders are the preferred choice for durability and reliability. (5mm bore for Size 17 motors, 100 CPR, 3M cable) (5mm bore for Size 17 motors, 200 CPR, 3M cable) (5mm bore for Size 17 motors, 400 CPR, 3M cable) (5mm bore for Size...

Linear and Rotary Encoders Single Ended / Differential Encoders Single ended encoders are the simplest to interface to external electronics. Modern digital readouts like the Velmex VRO have the necessary electronics for use with the more robust differential type encoders. Differential encoders are the preferred choice to greatly increase the integrity of a measurement system. AMO, ELGO, and EPC encoders sold by Velmex are differential. VRO Digital Readout for Encoders The Velmex model VRO is a high performance digital encoder readout. It offers an easy to read OLED display and a full...
