Module coupler
The module couplers are used to connect individual modules to each another. Type S (86 mm) module couplers are designed as pin-and-hole connections. The Type M, L and XL modular couplers (116/148/193 mm) are designed as polygonal connections.
The power supply and robot communication between the modules are transmitted through socket and pin contacts.
The module couplers are marked to indicate the installation position. The markings on both modules to be installed must be aligned with each other.
