A symmetric design allows the same product to be used in right- or left-hand positions, simplifying integration and inventory management.

Smart Electronic Latches for Enhanced Control and Efficiency

Southco's latest R4-25 product line addresses customer demands for enhanced electronic control and monitoring capabilities in challenging applications. These 12-volt actuators empower users to activate the latch using signals from their control system or a Southco controller.

For seamless wireless operation, the R4-25 works seamlessly with Southco's BluetoothTM controller. Furthermore, an integrated sensor communicates the presence of the door striker, confirming that the door is securely closed.

The R4-25 latches boast a symmetrical design that accommodates both right- and left-hand positions, streamlining stock requirements, expediting assembly, and optimizing inventory management. Moreover, the built-in cable mounting bracket eliminates the need to acquire or design a separate bracket.

Cindy Bart, Southco's Product Manager, explained that the R4-25 rotary latches expand the array of mechanical and electronically operated rotary latches.
