Original Press Release:

Slim Profile Push-to-Close Rotary Latch Provides Robust Performance with Low Closing Force

Concordville, PA, April 20, 2005 A new all-metal latch introduced by Southco uniquely combines the security of a rotary latch closure with the convenience of smooth push-to-close operation and a low closing force all in a compact package. Despite its narrow profile only 14.2 mm (.56") thick and 28 mm (1.1") deep, this new mini R4 rotary latch from Southco is a robust unit suitable for the demands of industrial enclosure doors or for storage compartment doors on off-highway and emergency vehicles routinely subjected to shock and vibration. This concealed latch style is designed to mount on the inside of an enclosure door and engage with a striker bolt mounted to the frame. The compact size of the latch minimizes internal protrusion within the enclosure. On opening, the latch cam rotates out of the body to disengage from the striker bolt. Upon closing, the striker bolt re-engages the latch cam and slides back into the latch body along with the cam. There, the striker bolt remains shrouded by the metal body of the latch, providing a strong, secure, protected connection. Available in multiple styles to satisfy a range of installation and actuation options, these mini R4 rotary latches are all hand actuated, either by direct action on the latch trigger or by remote actuation through rods or cables attached to the latch trigger. Different styles permit the actuation force to be applied either in line with, or perpendicular to the latch body. All styles are available for either left-handed or right-handed operation. The combination of low closing forces and remote actuation capability makes these latches especially useful for multi-point latching on doors with long spans that can flex when closing. Mounted at the extreme ends of the door and operated through rods or cables connected to a centrally located actuator handle, the easy-closing latches provide positive multi-point engagement with convenient single-point actuation. Common applications for the mini R4 rotary latch include: engine hoods, battery compartments, and access panels on off-highway equipment; storage compartments for emergency vehicles; electronics cabinet doors; and hinged panels such as access panels, safety guards, or enclosure doors on industrial equipment. Another common use is as a positive catch for a "second" door of a double-door set, one that can be accessed quickly by reaching around behind the door to trigger the actuator. Housings, internal components, and striker bolts are zinc-plated steel with a bright chromate finish. Cams and triggers are hardened steel that is zinc plated with a bright chromate finish. The internal springs are passivated stainless steel. Mounting options include a 7.2 mm (.28") through-hole style, and threaded styles with 1/4-20 or M6 threads.
