Latch can be locked/unlocked using electronic devices

Southco's new R4-EM Electronic Rotary Latch combines robust rotary latch security and electronic access convenience in a single integrated product. Unlike a standard mechanical latch linked with a separate solenoid actuator, the gearmotor drive in the R4-EM delivers a better feel to latch actuation and is more efficient in terms of lower power requirements and higher load capability. This provides versatility for performance across a wide range of applications from storage compartments on truck, bus, off-highway, construction, and agricultural vehicles, to RV baggage doors, and storage compartments or access doors on medical, electronics, self-service and industrial equipment.

A compact integrated latch design also makes the R4-EM easy to install, operate, and maintain. The 65 x 69 x 19mm housing requires minimal space and minimal protrusion inside the compartment, and installs simply with just two bolts to keep installation costs low. Its proven mechanical design and all-metal construction provide excellent vandal resistance with long-term durability and reliability.

This latch operates on 12-24V DC with a current draw during actuation of less than 500mA at 12V DC. Microprocessor control accepts a variety of electronic actuation signals including wireless devices such as proximity cards or RF key fobs, hard-wired numeric keypads or swipe-card terminals, smart-reader devices, biometric devices and remote computer or network security system signals. An integral microswitch option is available to provide a "˜latch opened/latch closed' status signal for remote monitoring.
