Triangulation sensor with a first metal lens barrel disposed in a first barrel mounting channel

A sensor device comprising:

• a metal sensor housing having a housing base;
• a metal optical frame having a frame base that is coupled to the housing base, a first device mounting plate orthogonal to the frame base and a first barrel mounting channel having a first sidewall extending obliquely to the frame base and a second sidewall extending obliquely to the frame base;
• a first metal lens barrel disposed in the first barrel mounting channel in contact with the first and second sidewalls, wherein the first and second sidewalls define a linear translation pathway of the first lens barrel along the frame base, and wherein the first lens barrel has an inner annular surface and three protrusions extending outward from the inner annular surface to define a first lens mounting structure;
• a first barrel fastener securing the first lens barrel to the first and second sidewalls;
• a first glass lens in contact with each of the three protrusions of the first lens mounting structure;
• and
• a first optical communication device secured to the first device mounting plate with a first securing device, wherein the first optical communication device is configured to be in optical communication with the first glass lens and is secured in a particular position in a first translation plane mutually defined by the first device mounting plate and the first optical communication device.
