Turck has added 18mm and 30mm capacitive barrel sensors with teachable
capabilities to its portfolio of capacitive sensors. The expanded product line comes
in two variants – teach by wire or teach by button.
The teach by button variant can be taught by a single press of a button,
saving valuable installation and configuration time. Both present and absent
media can be taught for a higher sensitivity teach.
The variant without a push button can be taught either by a teach
adapter or teach by wire (pin 5), which allows for a tamper-resistant
installation. Each variant is available in either PNP or NPN.
The 18mm housed version offers a 5mm sensing
range when flush mounted and a 7.5mm range when not. The 30mm housed version
offers a 10mm sensing range when flush mounted, with a sensing range of 15mm
when not flush mounted. The expanded offering can be switched between NC and
NO, and provides optical programming feedback through LEDs.
