KY-008 Diode Transmitter Module (KY-008 head) Key benefits Provides a compact, visible red laser source (650 nm) for aiming, alignment, detection, and control tasks. Solves accuracy and targeting challenges by producing a consistent, easy-to-see beam in a small package. Simple, low-voltage operation makes it straightforward to integrate into 5 V control and sensor circuits. Main features and specifications Model: KY-008 diode transmitter module with KY-008 head Operating voltage: 5 V Wavelength: 650 nm (visible red) Depth: 8 mm Size: 1.8 cm x 1.4 cm Functions: control, controllable pointer, detection, and related applications Practical uses (examples) Precision alignment: mount the module to provide a visible reference beam for optical alignment, machining setup, or assembly work. Indicator or pointer: use as a controllable pointer in demonstrations, fixtures, or positioning systems where a compact visible beam is needed. Sensor and detection projects: integrate into detection or control circuits that require a directed light source for triggering or sensing. Compatibility and integration Designed for use with 5 V control systems and sensor circuits Compact dimensions and shallow depth simplify mounting in tight assemblies and prototypes Safety and handling Always wear appropriate laser safety glasses when operating laser modules. This is especially important when working with invisible wavelengths, but also applies to visible lasers. Not for use by children or by persons who are mentally incapable of understanding safe operation. Do not give this product to individuals who do not understand its proper use. Follow standard laser safety practices to avoid direct eye exposure to the beam.
