"Machine users with a high degree of automation in particular benefit from IO-Link technology. The resulting transparency leads to better process control," explains Haydar Kartal, Product Management at SMC Germany. The ISA3#L series air gap sensors are used for non-contact distance monitoring and support control in machines. Unlike inductive and capacitive sensors, they detect the workpieces regardless of the material and can therefore be used universally. The ISA3#L series air gap sensors can perform distance measurements in the range from ten to 300 micrometers. A typical application is, for example, checking the correct position of a workpiece blank in a clamping device.

The benefits of IO-Link
Using the IO-Link interface, the ISA3#L series air gap sensors provide information about the supply pressure, back pressure, gap size and other diagnostic information with the process data to higher-level control units. This transparency provides a number of tangible benefits: continuous and complete insight into the process, optimization and troubleshooting, clogged orifices or interrogation nozzles are detected immediately, detected fluctuations in the supply pressure can indicate problems and complete information about devices and serial numbers in the network.

Another advantage is the ability to completely transfer all process parameters from the IO-Link master. This not only saves time, but also eliminates the risk of incorrect entries when programming manually.

Digital display with three colors
The air gap sensors can be operated with or without a control unit. Up to six units fit on a multiple connection plate, which can be connected to a control unit on the left or right side. The ISA3#L models have a two-line digital display. Three colors (red, green, white) indicate the distance of the workpiece from the support surface. Even at a distance or with a quick glance, the essential information can be reliably recognized.

The switching points are set in three steps. A key lock function prevents set values from being changed unintentionally. This increases the productivity and safety of systems. All sensors in the ISA3#L series are characterized by their extremely compact dimensions and low weight. They are therefore particularly suitable for installation in confined spaces, for lightweight construction and dynamic applications with mounting on moving units. With their high IP67 degree of protection, they are also ideally suited for use in harsh environments. as
