The R4-EM 8 Series Electronic Rotary Latch Series combines the efficient and robust performance of a rotary latch mechanism with simplified DC motor actuation. The R4-EM 8 Series is available with an optional door sensor, integrated connector and mechanical override bracket. Flexible, concealed installation provides vandal-resistance and accommodates a variety of cabinet designs. The R4-EM 8 Series enables simplified electronic locking and monitoring for applications that incorporate intelligent electronic control systems.

These robust latching solutions for doors and panels of heavy-duty equipment and vehicles combine rotary-action security with push-to-close convenience. Their compact design provides concealed operation, while tolerating misalignment on closing, engaging easily with low closing force, and latching firmly with a snug, secure fit. Durable materials, corrosion-resistant plating, and robust construction make these latches suitable for demanding environments. Easy operating mechanism and versatile actuation options make latches easy to adapt to a variety of installations.

Stylish, ergonomic design. Ambidextrous installation option permits consistent handle orientation. Lightweight, durable corrosion-resistant material. Rotary action cam for easy opening.

Easy to install and maintain, the 1 & 2 Series R4-EM delivers the convenience of electronic access control with the security of a proven, robust, all-metal rotary latch design in a compact, integrated package. Easy push-to-close operation and electronic actuation simplify access across a wide variety of applications. An optional microswitch provides feedback on latch status, and a delayed re-lock version keeps a door unlocked for manual opening/closing cycles. A gear-motor drive distinguishes the R4-EM latch from competitive solenoid driven electromechanical latches – with lower power requirements, higher load capability, and a better feel to latch operation. The delayed re-lock version provides the flexibility of controlling the unlock time while monitoring remotely with an integral microswitch option.

Convenient and reliable, the 4 & 6 Series R4-EM delivers proven electronic access control in a compact, lightweight integrated package. Easy push-to-close operation and simple installation make the R4-EM ideal for transitioning from mechanical to electronic access. An optional microswitch provides feedback on latch status. The R4-EM is available in both auto re-lock and delayed re-lock versions for added flexibility. The 4 & 6 Series R4-EM features a microprocessor controlled gearmotor with low power requirements. Multiple mounting configurations and a compact size afford easy integration into existing designs. The latch eliminates key management and accepts access control signals from a variety of devices including key fobs, keypads and proximity cards.

Southco’s R4-EM 5 & 7 Series Electronic Rotary Latch provides reliable electronic access control in demanding environments. With its corrosion-resistant plated-steel or stainless steel outer body construction and fully-sealed internal actuator, the Outdoor R4-EM provides reliable electronic locking that is resistant to moisture and dust. The embedded electronic control allows integration with an external control system and flexible, concealed installation provides vandal-resistance and accommodates a variety of outdoor applications.
