A series of food and beverage sensor products from AutomationDirect (Cumming, GA) includes AC and DC proximity, photoelectric sensors and quick-disconnect sensor cables. Compliant with the IP69K standard, the sensors withstand washdown conditions up to 212 °F and are made from FDAcertified material. The PFM 12 mm and PFK 18 mm proximity sensors have shielded or unshielded stainless steel housings and M12 quick-disconnect plug with gold-plated pins. The PFM series has a sensing range of 4-8 mm, while the PFK line has an 8-12 mm range. Models are available in a choice of 10-30 VDC PNP or NPN transistor outputs, and normally-open or complementary output configurations. Two series of 18 mm food and beverage photoelectric sensors are also available in 30 models and four styles: diffuse, polarized reflective, through-beam, and retro-reflective (for transparent objects); sensors are equipped with LED status indicators. IP69K-rated cables have also been released, and industry standard axial and right-angle M12 or half-inch micro connectors with open leads are available in 5- and 10-meter lengths.
