ipf electronic is expanding its portfolio of sensors with an IO-Link interface with a range of optical sensors with IO-Link. The optical sensors in the ON33, OT33, ON43, OT43, ON45 and OT45 series range from diffuse reflection sensors with transmitter and receiver in one device to light scanners, also with integrated transmitter and receiver. Thanks to the integrated background suppression, the devices in the OT33 and OT45 series are suitable for reliably detecting objects with strongly changing surface colors and suppressing components in the background. The OT43 series sensors, on the other hand, convert the object distance into a measuring signal proportional to the distance. The sensors are available in a total of three sizes, and the maximum switching distances of the devices range from 300 to 800 mm. All devices comply with protection class IP67 and are suitable for ambient temperatures from -25 to +60 °C (ON33, OT33, ON45, OT45), -30 to +60 °C (ON43) and 0 to +50 °C (OT43). The active surface of the sensors is made of plastic (ASA or PMMA). As the optical sensors with IO-Link are identical to the device series without IO-Link interface in terms of design and technical properties, they can easily replace sensors already in use.
