The OPB492P11 is a series of optical slot sensors manufactured by Optek Technology, based in Carrollton, Texas. It is designed for use in industrial automation systems, medical device applications, and the automotive industry. It has a housing size of 20 mm (L) x 10 mm (W) x 7.2 mm (H), and is available in NPN and PNP logic outputs. The device itself is an opto-electronic device that uses a photosensitive element and a light source within the same body. Its primary function is to detect the presence or absence of an object passing through its slot.The OPB492P11 is composed of two main parts: the emitter and the receiver. The emitter consists of a light emitting diode (LED) which emits infrared light. This light is focused on a specific area on the receiver, a phototransistor. When the object passes through the slot, this light is interrupted and the phototransistor is forced to its cutoff voltage. The device then supplies a digital logic level output based on whether or not its slot is blocked or not.The OPB492P11 also offers two distinct logic outputs: NPN and PNP. NPN logic outputs are low when the slot is blocked, and high when the slot is open. PNP logic outputs are high when the slot is blocked, and low when the slot is open. To ensure correct operation, the device has several design features to guarantee reliable performance, including optical shielding and electrical over-voltage protection. It offers an adjustable sensitivity, ranging from 2 to 10 mA, to accommodate for different ambient lighting conditions.The OPB492P11 is designed to operate in a wide range of ambient temperatures, from -40°C to +85°C. It also has a high immunity to interference from ambient light and other electromagnetic interference (EMI). This allows the device to operate in challenging environments such as factories, hospitals, and automotive test facilities. Its construction and design also make it a good choice for applications that require environmental sealing. The device can even be mounted in shock and vibration-proof sockets.The design of the OPB492P11 makes it an ideal choice for many different applications. It can be used as a presence or position sensor, to provide detection of an object passing through its slot. It is also used in medical devices to detect the presence or absence of liquid in a container, and the automotive industry uses it as a crash sensor for collisions and other impacts. It is also ideal for use in vending machines and cashier systems, as a detection device for coins or tickets.The OPB492P11 optical slot sensor is the perfect device for applications requiring reliable switching operation and immunity to interference. Its design features ensure that it is able to stand up to demanding environmental conditions, as well as providing assurance that a defined output is obtained. This makes it a great choice for a variety of applications such as medical devices, automotive test systems, and vending machines.
