Vishay Semiconductors IR Sensors for Presence & Proximity

Vishay Semiconductors IR Sensors for Presence and Proximity consist of two basic types: the AGC 0 and AGC P (for proximity). The AGC 0 modules feature a fixed gain, enabling reproducible object detection in variable ambient lighting conditions. These AGC 0 type sensors are suitable for both reflective and interruptive (such as a light curtain) sensor applications. The AGC P modules contain an automatic gain circuit, optimized to provide differential range information. The AGC P type sensors are useful for reflective sensor applications where information about an object's movement from the sensor is required.

Vishay Semiconductors IR Sensors for Presence and Proximity eliminate remote control problems with a fixed gain, which stabilizes the detection threshold and resulting detection distance. The sensors provide stable, repeatable performance under all lighting conditions, once the design of the optical parameters is determined. These sensors are ideal for a wide range of applications, including robotics, vending machines, and safety switches.

Features

Interrupter sensor
- Fixed gain type (AGC 0) with fast 300µs reaction time
- For light curtain and perimeter guard applications up to 30m

Reflective sensor
- For object detection applications (AGC 0) or object ranging applications (AGC P)
- Effective range from 0.2m to 2m

Applications

Safety switches for garage doors, elevator doors, gates, and industrial light curtains
Reflective sensors for toilets, urinals, faucets, hand dryers, and towel dispensers
