Tool Setting Gauge, Normally open, 5 meter cable, 6 wire
Tool setting gauge, normally-open contact, 5 meter cable, 6 wire.
Overview
The TM26D Normally Open is a tool setting gauge - a touch probe mounted on the machine bed that the tool tip touches to set Z zero or measure tool length automatically, rather than doing it by eye with a piece of paper or a manual jog.
Its contact is normally open: the circuit reads open at rest and closes the instant the tool touches the plate. This is a common wiring convention too, and which one a given controller expects on its tool-setting input varies - check that before choosing between this and the normally-closed TM26D Close in this range.
The cable is 5 metres with 6 wires, longer than the TM26D Close's 2 metres and 4 wires, suiting a controller or mounting position further from the probe. The extra two wires aren't detailed in this product's own listing - confirm the full wiring against the probe itself or your controller's manual before connecting it.

Questions
What does this do, exactly?
It's a tool setting gauge — a touch probe mounted on the machine bed that the tool tip touches to set Z zero or measure tool length automatically.
I've seen a "TM26D Close" listing too — what's the actual difference?
Contact type and cable. This one is normally-open (circuit reads open at rest, closes on contact) with a 5 m, 6-wire cable; the TM26D Close is normally-closed with a shorter 2 m, 4-wire cable. Which one you need depends on what your controller's tool-setting input expects.
Why would my controller want normally-open instead of normally-closed?
It's just a wiring convention — which one a given controller expects on its tool-setting input varies, so check that before choosing between the two.
The 4-wire version exists too — what are the extra two wires on this one for?
That's not detailed in this product's own listing — confirm the full wiring against the probe itself or your controller's manual before connecting it, rather than assuming.
