Background-Suppression Photoelectric Sensors
Contrinex's background-suppression photoelectric sensors pack powerful performance into their small M5 (threaded 5mm diameter) x 35mm long body. For comparison, a match is typically 3.7mm wide at the tip and 57mm long.
The 25mm sensing distance and rugged stainless steel housing make embedding it into assembly machines easier. Its 3.1mm diameter, 2m long, PUR-sleeved cable offers enhanced flexibility and robustness, for example, in installations with movement.
The performance gives a sensor with a narrow focused red-light spot of only 5 mm diameter at 10 mm or 8 mm diameter at a 20 mm distance with precise background suppression, enabling it to detect the presence of any obstacle regardless of colour, brightness, or angle. These sensors reliably detect the target, even if it is black or white.
Using IO-Link, the sensor can be switched into 'Fine', 'Fast' or 'Normal' operation modes with switching frequencies of 250 Hz, 1 kHz and 500 Hz, respectively. This can be controlled by a PLC, perhaps on different production runs or offline, using the PocketCodr mobile phone and tablet-based app before installation.
A preventative maintenance 'stability alarm' is available over IO-Link, reporting to the PLC when non-ideal detections are occurring or when they have been resolved to warn of potential problems.
