STAUBLI 14.0104 MS-S21
The MS-S21 is an accessory for Stäubli ID/S21 panel receptacles, specifically a small microswitch used to monitor if a connection is correctly closed. It changes its contact position just before the bayonet locking mechanism fully engages, providing a clear signal that the plug connection is properly made.
This is relevant in installations where not only the power connection itself is desired, but also an additional electrical feedback on the connection status. The microswitch is a changeover contact with three flat terminals measuring 2.8 mm × 0.5 mm, and it is designed for mounting with the corresponding Stäubli ID/S21 panel receptacle sockets. Mounting and installation details can be found in Stäubli assembly instructions MA075.
In practice, it allows the connection to be linked to a warning indicator or other monitoring system, so the operator can see when the connection is correctly established. This makes it suitable for professional environments where a secure and clear status of the plug connection is important.
