Inexpensive, Aligned Laser Modules in Miniature - Housing and Beam Axis Centered

This property speeds up assembly time. In light curtains, for example, each module no longer has to be aligned to match the photocell on the opposite side. It is usually enough to position the module mount once. The laser modules then only have to be placed into the mount and soldered.
The lasers also feature small dimensions. They have a length of 15.50 ± 0.05 mm; the diameter is 10.00 ± 0.05 mm.
This type of module is available with an output power of less than 1 mW and less than 5 mW. The wavelength is 650 nm, and the operating voltage is 3 VDC.
