About Biaobiao 3 Pack Optical Limit Switches Endstop With
Optical endstop limiters / photoelectric limit switches are much more accurate than mechanical switches, which is essential for printing certain precision instruments. This module is different from the mechanical micro switch, and it will not cause errors due to deformation of the mechanical structure for a long time. The integrated high-precision comparison IC LM393 has higher precision than the simple photoelectric switch. The ordinary photoelectric switch will generate current and voltage fluctuations during the process of approaching the closing, which will cause some circuits to generate false triggers. This module will only be in LOW and Change between HIGH. This is especially important for the Z axis of 3D printers. Size:21.1mm * 25.3mm *14mm Voltage: DC 5V Package Include: Photoelectric Switches module * 3pcs 70cm Line * 3pcs
