70103991 Dot laser module, red, 650 nm, 12 VDC, 9x20 mm, class 3R

This type is a dot laser for the projection of a red laser dot. This diode laser module is characterized by a high degree of efficiency and a long service life. The laser module is equipped with control electronics and only needs to be connected to a voltage source (DC voltage). The operation of this laser module is possible without series resistor or control electronics at many existing voltage sources, e.g. small power supply units or also at the 12 Volt on-board power supply of a car. Typical applications are low-cost applications. The laser module has fixed optics and can be used in light barriers, levelling devices or pointer applications. The temperature range allows the use in many applications.
