Colleagues, here is a device. Electrical connections: 5 wires.
Connector: 5-wire, compatible with BLTouch:
Black — GND (ground)
Red — +5V
Yellow — Servos (rod control)
White — Probe (output signal)
Has anyone tried this? I'd love to hear about your experience using it as a probe. The ad highlights a very appealing feature—the
trigger weight is only 5 grams.

That is a version of BL-Touch sensor for 3D printers, usually 5 wires, +5V, 2XGND, sense pin and a servo pin that drives the sensing bit up/down.
Should be pretty easy to make it work, the "push sensor down"/"pull sensor up" logic should be similar to RC servo, but i never bothered to check, despite having several in use on Voron's i built.
Precision is quite high and temperature drift is quite low, but i doubt it is precise enough for a mill, should be more than enough for most routers.
