Capacitive barrel sensors with teaching functions
Turck’s 18 and 30mm capacitive barrel sensors come 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 higher sensitivity. 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 18 mm housed version offers a 5 mm sensing range when flush mounted and a 7.5 mm range when not flush mounted. The 30 mm housed version offers a 10 mm sensing range when flush mounted, with a sensing range of 15 mm when not flush mounted.
