EE-SX498 Application Field and Working Principle

EE-SX498 is an optical sensor that detect an object passing through its slot type, and is classified under the Optical Sensors - Photointerrupters - Slot Type - Logic Output category. It is typically used in motor control, speed detection, and process control applications, and is a reliable way to detect the presence of objects.

Features

The EE-SX498 has a number of features that make it suitable for use in a variety of applications. It has a 3 mA supply current, which is low enough to make it suitable for battery-powered applications. It also has a maximum output current of 30 mA, which allows it to handle higher loads. It has a wide operating voltage range of 4.5 V to 30 V which makes it compatible with many other systems. It has a fast response time of 1 ms, and a wide operating temperature range of -20°C to +105°C. It also has high reliability, as it is shock-proof and vibration-proof.

Technical Specifications

The maximum forward voltage is 2.5 V, the reverse voltage is 40 V, the output current is 30 mA, and its on-state resistance is between 1.1 W and 2.3 W. The turn-on/off time is 1 ms, and the operating temperature range is -20°C to +105°C. Its external dimensions are 10.2 x 8.0 x 7.6 mm, and it weighs 13.5 g. It is UL approved, and is RoHS compliant. It operates on a forward voltage of DC4.5 ~ 30 V, and its insulation resistance is greater than 10^8 Ohms.

Working Principle

The EE-SX498 optical sensor has an LED (light emitting diode) and a phototransistor, both of which are sealed in an encapsulating resin. The LED emits infrared radiation which passes through a slot in the housing. When an object passes through the slot, the phototransistor is configured in a collector-emitter circuit and the beam of infrared radiation is blocked, causing the phototransistor to switch off. This switch-off signal is detected by an microprocessor, which can then control the system accordingly.

Advantages

The EE-SX498 has several advantages, such as a low supply current, wide operating voltage range, fast response speed, high reliability, and wide operating temperature range. Additionally, its small size and light weight makes it ideal for applications where size and weight are of importance. Furthermore, it is UL approved and RoHS compliant, which makes it suitable for a range of industrial applications.

Application Fields

The EE-SX498 is commonly used in motor control, speed detection and process control applications. It is used to detect the presence or absence of an object and can be used in a variety of applications such as material handling, printing, packaging and machine tools. Additionally, it can be used as an limit switch or feed control device.

Conclusion

The EE-SX498 is an optical sensor that is classified as an Optical Sensors - Photointerrupters - Slot Type - Logic Output, and is typically used in motor control, speed detection and process control applications. Its advantages include a low supply current, wide operating voltage range, fast response speed, high reliability, and wide operating temperature range. Additionally, its UL approval and RoHS compliance make it suitable for a range of industrial applications.
