One of the unique product lines that Gibson represents is Captron: https://www.captron.com/

The specialize in Capacity Touch buttons like those shown below, but they do a lot more as well.

The CANEO series with IO-LInk is a personal favorite as you can get a 22mm switch that's very ergonomic and program it to do a multitude of things, from off delay touch to toggling it's output and various colors of light, all on a 5-pin M12 cable.  But you can get a wide variety of labels on the switch as well as fully custom labels if you want.  Last summer while I was on vacation on a cruise ship, I noticed Captrons buttons on all the large sliding doors.  If you pay attention you will find their products all over the place.

Using the same technology, Captron also produces Two-Hand anti-tie down switches.

A unique product that is used in robotic work cells and other spaces is the Optical sensors.  For determining tooling offsets in robotic work cells with repeatability of 0.01mm, the x/y axis through beam unit is a great solution for a common problem.

I've been very impressed by the products and the company.  Definitely a hidden gem.
