Southco's electronically controlled rotary latch. A gear-motor drive distinguishes the R4-EM latch from competitive solenoid driven electromechanical latches – with lower power requirements, higher load capability, and a etter 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. 12-24v DC operation and 2-wire or 3-wire input options, and the ability to accommodate multiple input signals offers versatility for installation and integration with new or existing access control systems. Southco's electronic rotary latch operates as a part of a kit that includes an EA-A02-002 Battery pack or equivalent power supply, and Southco;s Remote Access Controllers EA series.
