FAQs

What is a piezo keypad and how does it work?

A piezo keypad is a type of keypad that utilizes piezoelectric technology to detect user input. Piezoelectric materials generate electrical charges in response to mechanical pressure. When a user applies pressure to a piezo keypad, it generates an electrical signal that is detected and interpreted as a key press.

What are the benefits of using piezoelectric technology in keypads?

  • High reliability and durability
  • Fast response time
  • Resistance to environmental factors such as moisture, temperature, and chemicals
  • Long lifespan with millions of actuations
  • Low power consumption

What are the advantages of using piezo keypads?

  • Durability and resistance to wear and tear
  • Waterproof and resistant to harsh environments
  • Long lifespan
  • No moving parts, reducing the risk of mechanical failure
  • High sensitivity and responsiveness
  • Can be operated with gloves or in wet conditions

How are piezo keypads different from traditional mechanical keypads?

Unlike traditional mechanical keypads that use physical switches, piezo keypads rely on the piezoelectric effect to detect input. This eliminates the need for moving parts, making them more durable and less prone to mechanical failure. Additionally, they are often more resistant to water and environmental factors.

What industries commonly use piezo keypads and keypad switches?

  • Industrial automation and control
  • Medical and healthcare
  • Transportation and automotive
  • Aerospace and aviation
  • Security and access control
  • Public kiosks and self-service terminals

Are switchplates available for piezo keypads?

Yes, switchplates or protective overlays are commonly available for piezo keypads. These switchplates provide an additional layer of protection, preventing accidental key presses and enhancing the overall durability of the keypad.

How do piezo keypads enhance security in access control applications?

  • Anti-tampering features: Piezo keypads are resistant to physical tampering, making it difficult for unauthorized individuals to manipulate the keypad.
  • Covert operation: The lack of tactile feedback in piezo keypads makes it difficult for potential intruders to detect the pressed keys, enhancing security.
  • PIN code protection: Piezo keypads can be used to enter PIN codes or passwords, adding an additional layer of security to access control systems.

What customization options and requirements are available for a custom piezo keypad?

When customizing a piezo keypad, you have various options such as choosing the size, shape, layout, materials, graphics, backlighting, and additional functionalities. Common customization requirements include meeting industry standards, IP-rated sealing for water and dust resistance, compliance with specific specifications, resistance to harsh conditions, and integration into larger systems.
