Not standard issue, but OTQ8
The optical sensors OTQ80470, OTQ80475 and OTQ80477 from ipf electronic are highly developed devices that are characterized by their versatility. The sensors are housed in robust plastic housings via a teach-in function for easy setting of the sensing range. With an operating voltage of 10 to 30V DC and a maximum current consumption of 40mA, they are also energy-efficient and reliable.
The OTQ80470 works with a pin-point LED that emits a point-shaped, pulsed red light with a wavelength of 644nm. The sensing range of the sensor extends from 3 to 132mm, the adjustment range is 20 to 120mm. The sensor is short-circuit and reverse polarity protection, making it particularly robust and safe in operation. With a switching frequency of up to 1kHz and a response time of 0.5ms, the sensor with background suppression (irrelevant objects in the background are reliably suppressed) is extremely fast and precise.
The OTQ80475 differs from the other sensors presented here in its intensity differentiation, in which the diffuse-reflection sensor evaluates the intensity of the light reflected by an object. It works with an LED (point-shaped light) that emits pulsed red light with a wavelength of 644nm. The sensing range of the sensor extends from 20 to 200mm. With a switching frequency of up to 2kHz and a response time of just 0.25ms, it is particularly fast and is suitable for applications that require high-speed detection.
The OTQ80477 with background suppression uses a linear light beam and has a sensing range of 20 to 120mm. The diffuse- reflection sensor is particularly suitable for detecting objects with rather uneven or irregular surfaces due to the linear light beam. The wavelength of the emitted red light is also 644nm. The device has a switching frequency of 250Hz and a response time of 2ms. The sensors OTQ80470, OTQ80475 and OTQ80477 offer a number of advantages that make them an excellent choice for many industrial applications:
Due to the background suppression and the point-shaped or linear light beam form, the sensors (OTQ80470 and OTQ80477) can reliably detect objects in front of a background, almost regardless of the object surface and color.
The teach-in function enables all sensors to be quickly and easily adapted to different operating conditions. This saves time and reduces the effort involved in installation and configuration.
The plastic housing and IP67 degree of protection make the sensors resistant to dust and water, allowing them to work reliably even in demanding environments. The sensors also have M3 threaded sleeves made of stainless steel for easy and secure mounting. This increases the life of the sensors and reduces maintenance costs.
The sensors in this series can be operated in both light-on/dark-on mode so that, for example, the switching output is active when the sensor recognizes the light beam reflected by the object (light-on mode). This makes the devices versatile and allows them to be flexibly adapted to different applications and requirements.
With response times of just 0.25ms to 2ms and switching frequencies of up to 2kHz, the sensors are ideal for applications that require fast and precise detection. This improves both efficiency and performance in dynamic processes.
The sensors are connected via 4-pin M8 plug-in contacts. The teach-in function is activated using a ferromagnetic tool. The sensors also offer interference suppression, which prevents mutual interference and thus ensures reliable detection with several sensors in a small installation space.
