Feature: 1. Excellent Gear: All metal gear has high temperature resistance and strong bearing capacity, effectively protecting the main body of the gear box motor. 2. Multiple Usages: Photoelectric incremental rotary encoder, which can be used to measure the rotating speed, angle, acceleration and length of objects. 3. Stainless Steel Shaft: 6mm D type output shaft design, made of stainless steel, impact resistant, improving bearing quality and service life of gear motor. 4. Stable Operation: NPN collector open circuit output mode, and side outlet mode, which ensures stable and reliable operation, with less interference. 5. Wide Application: Used for measuring various displacement changes, such as intelligent control, full automatic fixed length leather cutting machine, competition robot, etc. Specification: Item Type: Photoelectric Encoder Outer Diameter: Approx. 39mm / 1.5in Type: Solid Shaft Shaft Diameter: Approx. 6mm / 0.24in Working Voltage: 5-24V Outgoing Mode: Side Out Cable Length: Approx. 1.3 meter / 4.3ft Output Mode: NPN collector open circuit Purpose: Used to measure the rotation speed, angle, acceleration and length of objects.. Package List: 1 x Photoelectric Encoder Note: 1. The encoder shall not be rigidly connected with the shaft. The photoelectric encoder with elastic connector is a high accuracy sensor. It is strictly prohibited to knock during installation.2. Please do not put the encoder output line and power line together or in the same slot, or near the switchboard.
