Southco electronic rotary latch provides a simple, versatile electromechanical latch solution for a variety of applications. Easy to install and maintain, the 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. Industry applications includes automotive - truck hoods, storage compartments, computers, construction equipment, off-highway vehicles, farm equipment, display cases, electronic enclosures, industrial equipment, marine, medical equipment, recreational vehicles, self-service equipment and storage lockers, transportation - bus, truck, aerospace, rail.
