Features of Flex-300

Heavy duty applications

For heavy duty applications, a special seal prevents dust from entering the locking mechanism and electrical contacts when the two plates are coupled. (Load Capacity: 300kg/Allowable static moment (Tx, Ty) :270kgf・m)

Self-sealing pneumatic ports

There are ten pneumatic ports in the Master plate (Rc3/8). Eight of the ten ports are self-sealing, which automatically shut off air pressure when uncoupled and allow for easier air control in the system.

Large misalignment correction capability

The unique design corrects misalignment when the Master and Tool plates couple. An approach sensor system, built into the plates, verifies coupling capability.

Superior fail-safe locking mechanism

BL’s unique lock/unlock mechanism contains a mechanical fail-safe feature which does not allow the Master and Tool plates to uncouple if the air pressure is shut off.
