PTL-22 illuminated piezo switch, 22 mm

The PTL-22 is a piezo switch with a flat face and an illuminated ring, so the activation area is easy to locate. It mounts on an M22 x 1 thread with a front diameter of 24.6 mm, in aluminium 6061 T651 or stainless steel 303, 304 or 316. The ring LED comes in single colour, 2-colour or RGB. 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 PTL-22 is available with PT Plus inside.

PTL-22 questions

What LED options does the PTL-22 have?

The ring LED is available in a single colour, 2-colour or RGB, at an LED voltage of 3.3 V, 5 V, 12 V or 24 V. The light guide is polycarbonate.

What thread and front diameter does the PTL-22 have?

The PTL-22 mounts on an M22 x 1 thread. The drawing gives a front diameter of 24.6 mm and a 20 mm body. The datasheet gives a mounting torque of 2.5 Nm.

Can the PTL-22 be used with gloves or wet hands?

Yes. The PTL-22 datasheet lists activation with gloves and wet hands, and reliable operation with snow and mud.
