R4-EM Electronic Rotary Latches
R4-EM Electronic Rotary Latches
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.
