New Southco Cam Latch Option Adds Push-to-Close Convenience

An expanded selection of Southco® E5 cam latches now adds intuitive push-to-close convenience to the existing versatility and affordability of this modular line. Styling and access control options include hand, tool, and key-actuated models. The new designs satisfy both single-point and two-point latching installations across a variety of commercial applications ranging from light-duty use with covers and access panels in HVAC, office furniture, and industrial machinery, to storage compartments in recreational vehicles and bus, truck, or railway applications.

The ease of operation in single-point latching applications incorporates a spring-loaded ramped cam. As with conventional cam latches, the mechanism rotates to disengage from the keeper. But once the panel is opened and the cam rotates back to the ‘closed’ position, the ramp-shaped face of the retractable cam functions like a push-to-close mechanism. This assures safe, trouble-free operation even if the door is shut with the cam in the closed position.

For configuration flexibility in multi-point latching applications, the new E5 two-point-latching adapter connects with cable actuators used to drive Southco R4 rotary series latches. In this design, the driver and actuators return to their original positions as soon as the driver is released after opening, while the rotary latches provide push-to-close engagement with robust latching security.

Access control options for all versions range from hand-actuated wing-handle, t-handle, and l-handle styles to tool-actuated head styles. Those include conventional slotted, hex, square, and triangle-shaped drivers, as well as industry-specific tool options such as Bellcore 216, Bellcore electronics, and railway standard drivers. Multiple key-locking configurations offer flexible key-code options. All latches, regardless of head style, include a latched / unlatched position indicator.

Like other Southco E5 cam latches, the new push-to-close designs are easy to install in panels ranging from 1mm – 6mm thick (0.04in to 0.24in), using single-hole panel prep. Head styles are available in standard bright chrome and black powder-coated finishes. Cam bodies include an internal o-ring and a sealing washer to accommodate NEMA 4 and IP-66 applications. Pull-tab and padlock bracket accessories are also available to customize installations to specific user requirements.
