New optical sensors from IPF

OTQ80470, OTQ80475 and OTQ80477 are the descriptions of three new additions to IPF wide range of optical sensors. Quite apart from their small design (15.8mm x 8mm x 21.1mm), the devices have several interesting practical features. Starting with simple mounting, the diffuse reflection sensors can be easily positioned and precisely adjusted using the visible red light.

The OTQ80470 and OTQ80477 are characterized by their background suppression. This makes these sensors suitable for the high-precision detection of objects, virtually independent of the reflectivity of the surface, while any interfering backgrounds are reliably suppressed. The OTQ80470 works with a point-shaped, pulsed red light (wavelength 644nm), which enables objects to be detected with very high precision. Due to its high switching frequency of up to 1kHz and a response time of at least 0.5ms, the sensor also reacts at lightning speed and is therefore recommended for use in high-speed processes, among other things. The sensing range of the OTQ80470 is 20 to 120mm.

The OTQ80477 with background suppression and a sensing range of 20 to 120mm also uses a linear light beam for detection, which can be particularly advantageous for the reliable detection of objects with rough or uneven surfaces. With a switching frequency of 250Hz and a response time of 2ms, this device is also ideal for applications in which objects move during detection.

The new products are completed by the OTQ80475 as an economical alternative. This sensor with a range of 20 to 200mm works with intensity differentiation, whereby the diffuse reflection sensor evaluates the intensity of the transmitted light reflected by an object. The diffuse reflection sensor uses a pin-point LED with pulsed, visible red light as a transmitter. With a very high switching frequency of 2kHz and a response time of just 0.25ms, this sensor is characterized by a fast reaction time. The OTQ80475 is therefore ideally prepared for applications that require high speed detection.

Another plus point is that the sensors in this series can be operated in both light-on and dark-on mode. This means that the switching output is either active (light-on mode) or inactive (dark-on mode) in the event of a light signal. This feature increases the versatility of the devices, as they can be flexibly adapted to different tasks and requirements.

All optical diffuse reflection sensors are also resistant to dust and water in accordance with degree of protection IP67, i.e. conditions that frequently occur in particularly harsh industrial environments.
