Introduction

The 27300 family of reflective optical sensors is a logic output version of VISHAY\'s 27000 series. The 27300 family of optical sensors operates in the visible range, and offers 24-bit logic output for sensor applications. Reflection type optical sensors have a large sensing range, and respond to objects that are too far or too large to fit into conventional proximity sensors. They are well suited for applications in contexts where space is limited, such as manufacturing, assembly, surface detection, and guiding.

Features of 27300 Logic Output Sensors

The 27300 family of optical sensors is designed with narrow acceptance angle to reduce the signal from ambient light sources and prevent interference with other optical sensors. The 27300 optical sensor features logic (on/off) output, high isolation between output channels, fast switch-on and switch-off times, low light intensity sensitivity, an operating temperature range of -25 to 65℃, and overvoltage protection up to 24V DC. Sensors also feature adjustable optical intensity levels, from 8 to 115K Lux (White LED). The MODUS27-X sensor features a specific output logic type, while the PL3000-X sensor features optional external programming.

Application Fields

The 27300 reflective optical sensors can be used in space-constrained applications due to their slim and compact design. Typical applications for these sensors include surface end-of-travel detection, guiding and positioning systems, automated industrial storage systems, and medical equipment. 27300 logic output optical sensors are also frequently used in industrial automation, transport and logistics, packaging automation, and machine tool applications.

Working Principle

The 27300 sensors are based on an infrared optical sensing principle, which uses an emitter to radiate infrared light in a narrow angle towards a reflector or surface. When an object interrupts the beam, the sensor switches from its active (OFF/high) state to its inactive (ON/low) state, allowing the application logic to control the system accordingly. These sensors offer feedback in only one direction, whether the cycle was successful in detecting an object, hence their logic output type. Furthermore, the sensor\'s field-of-view is adjustable, meaning you may choose to add or reduce the field angle of the target area.

Conclusion

The 27300 family of reflective optical sensors offers a logic output type suitable for applications such as end-of-travel detection, guiding, positioning systems, and automated industrial storage systems. Due to the sensor’s slim and compact design, it is an ideal choice for space-constrained applications. Furthermore, these sensors are designed with narrow acceptance angle to reduce the signal from ambient light sources and a broad operating temperature range that makes them well suited for a number of industrial applications.
