Sensor-Actuator-Interface (SAI)

There are good reasons for the fact that Weidmüller belongs to the market-leaders in the distributor sector worldwide. In their development of SAI distributors, Weidmüller engineers have always concentrated on achieving rational, cost-effective installation concepts, and – in cooperation with major users – have supplied the markets with well-conceived products which set standards in terms of functionality and quality throughout the globe. The best example of this is the new SAI Universal Pro System for sensors and actuators, which further optimises installation time and reliability.

Product group overview

	SAI - active / field buses SAI AU PROFIBUS-DP Wireless Profibus-DP Gateway Extension Modbus TCP CANopen DeviceNet AS-Interface Accessories	The SAI Active range includes fieldbus components for PROFIBUS-DP, DeviceNet™, CANopen, Industrial Ethernet and AS-Interface, which helps to achieve consistent, modular and decentralised industrial automation. Automation technology based on such a system is transparent, efficient and cost-effective. In order to be able to exploit the cost-savings effect of fieldbus-networked I/O systems to the full, the input and/or output units should be brought into the process decentrally. Modules in class of protection IP 67 are used in contaminated and/or very damp environments.

	SAI - passive M12 distributor M8 distributor M5 distributor	Passive M12 distributors are available in all conceivable forms and configurations. Furthermore, a number of special versions, e.g. SAI distributors for EX zones or the ergonomic M8, are available only from Weidmüller. These innovative products are backed up by numerous proprietary rights.

	SAI lines Sensor/actuator cables Data cables Valve plug-in connector Valve plug with integrated seal Trunk cables	Weidmüller offers a large and comprehensive range of sensor-actuator cables. We provide both, sensor cables as well as bus and valve cables of various sizes and lengths. If you cannot find a specific product or a product in the desired length, just contact us.

They are easy to install and guarantee outstanding reliability. The components are matched up with each other so that the installed housing fulfils the protection class IP67 and no moulded encapsulation is required. Additionally, all I/O PCB connectors are 100% reflow-compatible (and compatible with all other soldering method). Because of their excellent variability, Weidmüller's SAI empty enclosures are perfect for use with customised designs that customers can implement themselves.
