Introduction

Optical sensors are widely used in a variety of applications, ranging from industry automation to medical devices. Transistor output photo interrupters, in particular, have proven to be an effective implementation of optical sensing due to their ability to switch an output current with a single photodetector. The EE-SX912-R from Panasonic is a transistor output photo interrupter of the "slot type" variety which is highly reliable, compact, and simple to use. This article will cover the features of the EE-SX912-R, the typical application field, and its working principle.

Features of the EE-SX912-R

The EE-SX912-R is a small size (30.0mm x 5.3mm x 12.6mm) photo interrupter with transistor output. Its package type is slim, so it can be installed in limited spaces. It has a detection distance of 2mm - 4mm and a supply voltage of 4V - 24V, making it suitable for various applications. Its output current is 40mA and output resistance is 400Ω. It is designed to operate with a lifetime of 10 million cycles and withstands an operating temperature range of -25°C to 85°C.

Typical Application Field

The EE-SX912-R is ideally suited for applications requiring a reliable switch point. It finds wide use in safety devices, motor speed controls, step motors, and machine automation. Similarly, they can be used in medical applicances such as blood pressure monitors, heart rate monitors, and catheters. They can also be used in telecommunications, navicular position sensing, conveyer belts, and robotics arms.

Working Principle

The EE-SX912-R works by having a photodetector mounted directly below a slotted mask which blocks the infrared light from the photodetector. When the slotted mask is broken by an object interrupting the sensor, the photodetector is activated and the switching element conducts current and triggers an output signal.The EE-SX912-R is reliable and simple to use. Its photodetector is integrated into the slot which ensures an accurate switch point. The design increases the durability of the switch, as its transmission and reception are not disturbed by dust and other debris which can affect other optical sensors.

Conclusion

The EE-SX912-R is an optimal choice for applications requiring a reliable switch point. Its small size and wide supply voltage range makes it suitable for a variety of applications, and its lifetime of 10 million cycles ensures its durability. Its easy-to-use design is aided by its integrated photodetector, making it a reliable sensing solution in many areas. Regardless of the application, the EE-SX912-R from Panasonic can prove to be an effective and durable solution.
