The Contrinex Series 300, a range of flush mounting inductive sensors with housing diameters of just 3mm and body lengths of only 22mm, is now available from Aerco. Despite its small size the Series 300 has a sensing distance of 1mm and a switching frequency of 3,000Hz. This makes it ideal for applications where the detection of extremely small components is important such as the verification of small part presence in automatic assembly machines or on robotic pick and place systems. Because they are so small they can be embedded within gripper fingers to detect components on contact.
These sensors have short circuit, inverse polarity and overload protection, an LED indicator, and are capable of switching 100mA (connected to a 10 to 30Vdc supply).
