PTF-22 piezo push button, 22 mm, flush
The PTF-22 is a piezo push button with a flat, flush face 25 mm across on an M22 x 1 mounting thread. The housing is aluminium 6061 T651 or stainless steel 303, 304 or 316. It has no moving parts, is sealed to IP68 and IP69K and rated IK10. It is used in food processing, parking meters, sanitary products, pools and spas, clean rooms, oil and gas, and self-service terminals.

Does the switch need to do more than switch?
- CommunicationUART, SPI, I2C, Modbus, CAN or LIN
- Logic and functionsProgrammable logic and timing in the switch
- Self-diagnosticsAnswers a poll to confirm it is fully operational
- −40 °C to +85 °CSame feel across the range, temperature compensated
Then specify a switch with PT Plus inside.
PT Plus puts an onboard MCU inside any PT switch body from 22 mm. It fits the same panel cutout and looks identical from the front. The PTF-22 is available with PT Plus inside.

What thread and front diameter does the PTF-22 have?
The PTF-22 mounts on an M22 x 1 thread. The drawing gives a front diameter of 25 mm, a 1 mm front flange and a 16 mm body behind it. The datasheet gives a mounting torque of 2.5 Nm.
Can the PTF-22 be used with gloves or wet hands?
Yes. The PTF-22 datasheet lists activation with gloves and wet hands, and reliable operation with snow and mud.
Can the PTF-22 be pressure washed?
Yes. The PTF-22 is sealed to IP68 and IP69K and its datasheet rates it washdown-proof up to 100 bar. With no moving parts there is no gap for dirt or germs to build up.
