Gasonics 0510X-LA24-ABA Inductive Sensor
Introduction:
The Gasonics 0510X-LA24-ABA is an industrial-grade inductive proximity sensor. It is used to detect the presence of metallic objects (such as wafers, robot arms, or chamber lids) without physical contact. It operates on the principle of electromagnetic induction, generating an oscillating field that is dampened when a metal target enters the sensing range.
Technical Specifications:
- Sensing Principle: Inductive (Oscillator-based)
- Housing Size: M12 or M18 cylindrical barrel (Standard industrial size)
Detailed content
- Supply Voltage: 10-30 VDC (Typically 24VDC)
- Output Type: PNP (Sourcing) or NPN (Sinking) – usually 3-wire
- Sensing Distance: 2mm to 8mm (Sn) depending on target material
- Switching Frequency: up to 200 Hz
- Protection Rating: IP67 (Dust and water resistant)
- Housing Material: Brass or Stainless Steel
Functional Features:
- Non-Contact Detection: No moving parts, ensuring long life and no mechanical wear.
- Robustness: Resistant to dust, oil, and moisture, suitable for harsh vacuum and cleanroom environments.
- Short Circuit Protection: Built-in protection against output short circuits.
- LED Indicator: Visual feedback for output state (ON/OFF).
Application Scenarios:
- Wafer Presence Detection: Sensing if a wafer is present on the electrostatic chuck or transfer arm.
- Chamber Interlocks: Verifying that the chamber door is securely closed (via a metal flag) before enabling RF power.
- Robot End-Effector Sensing: Confirming that a robot arm has reached its target position.
- Lid Position Sensing: Detecting if the process chamber lid is raised or lowered.
