• Optical Sensors - Photointerrupters - Slot Type - Transistor Output:

GP1S73P2 is a slot-type photointerrupter offering transistor output, and is part of a range of optical sensors produced by SHARP Corporation. A photointerrupter can detect the presence or absence of objects when they interrupt or pass through a light beam, and are widely used in various applications such as paper-currency counting and vending machines, and motor-controller limit switches. GP1S73P2 is designed for a wide range of automotive and industrial applications where its superior reliability and low-power consumption are beneficial.

GP1S73P2 consists of a light-emitting diode (LED) and an NPN-type phototransistor pair arranged in an opposite configuration. The LED emits a beam with the same wavelength as the phototransistor’s peak sensitivity, and when an object interrupts the light beam, the collector-emitter path of the phototransistor is de-energized. A minimum rated load of 12V and 0.1mA is required to power the device. The device also has a high isolation voltage between the emitter and collector of 2500Vrms. GP1S73P2 is designed to have high sensitivity over a wide range of detection areas and has a fast response time of 3µs.

When used as a transitive switch for object-detection purposes, the LED and phototransistor must be placed in such a way that the light beam passes through the slot in the object. The light-emitting diode used in the GP1S73P2 allows it to achieve superior performance in narrow slots with a minimum width of 0.3mm. The switching current and voltage is determined by the LED, and the device is designed to have a high-switching current of 5mA and a low-switching voltage of 0.6V.

As a safety feature, the device has integrated an over-current-protection which is triggered when the current going through the device exceeds 8mA. The device also features built-in protection against static electricity, which is important for automotive and industrial applications. The device is also RoHS-compliant, meaning that it meets all the environmental requirements set out by international regulations.

GP1S73P2 is designed to have a wide range of operating temperatures from -40°C to +85°C, making it suitable for use in extreme temperature environments. The device has an operating voltage range of 3V to 12V and is designed to be highly reliable with an operating lifetime of over 5 million cycles. The device also features a low power consumption of 0.2mA, making it an ideal choice for use in battery-powered or energy-saving devices. In addition, the device is also packaged in a compact, 2-pin SOP housing, making it suitable for applications with space restrictions.

GP1S73P2 is a versatile, reliable and cost-effective optical sensor option for a wide range of applications. Its high sensitivity over a wide range of detection areas, fast response time, and low power consumption make it an attractive choice for automotive and industrial applications where accuracy and reliability are essential.
