Compact inductive sensors
Miniature sensors detect position and presence
The installation space for the corresponding sensors is often very limited, especially for position and presence detection. As a solution to this problem, Contrinex has developed the smallest inductive miniature sensors available on the market with fully integrated electronics.
Inductive miniature sensors for position or presence detection are required in many areas of industry. One example of the use of such compact sensors is the automated production of solar cells. In these production systems, the silicon wafers are transported between the workstations using compact two-finger robotic edge grippers. To prevent damage to the wafer surfaces, it must be ensured that the robot's gripper jaws are fully open before the wafers are lifted. This important task is performed by Contrinex's inductive ultra-miniature sensors, which are mounted directly above the tops of the gripper fingers. They reliably detect the position of the jaws and thus avoid scrap costs.
"Fit-and-forget" sensors
The sensors are available in round stainless steel housings with diameters of 3 to 4 mm, in stainless steel housings with an M5 thread or in square stainless steel housings with an edge length of 5 mm. The "MiniMini" sensors from Contrinex are also particularly compact: they are available from a size of just 12 mm with diameters of 3 mm.
Depending on the control system, the sensors can be supplied with PNP or NPN outputs as NO (Normally Open) or NC (Normally Closed) variants for detecting switching distances of up to 2.5 mm. An IO-Link interface is also available for communication with the PNP-NO variants for simple application-specific parameterization. With all miniature sensors, the proven technology ensures simple and fast installation and commissioning ("fit-and-forget"). Further advantages of the sensors are the very low power consumption and the wide operating temperature range of -25 °C to +70 °C.
At SPS 2023 in Nuremberg (November 14 - 16), Contrinex will be showcasing its portfolio, including miniature inductive sensors. Visitors will find the Contrinex stand in Hall 7A, Stand 430.
