I found a really cool little 24VDC relay interface with four channels and then some inductive proximity switches on Amazon. The relay interface is made for light curtain type safety switches but can be used for any transistor based switch like a proximity switch. It has DIN rail mount, wiring terminals, and LED indicators. The proximity switches are inductive with a 4 mm sensing range. Inductive prox switches will sense any type of metal including aluminum and switch on when the metal comes into the 4mm range. They have a built in LED indicator also. I posted a video for your viewing pleasure. The green terminal unit at the end with the LEDs is the relay interface showing the X and Y axis completing the homing cycle.
