Why are the benefits of electronic access technology convenience and security still relatively scarce in more specialized applications, such as computer and electronics enclosures, as compared to their broad acceptance in consumer automotive applications? Well, that dynamic could be changing, thanks to new modular implementations of electronically actuated latch and lock systems.
New Options Available
Today, electronic mechanism designs that require little or no redesign to satisfy existing enclosures are opening up new options for affordable, reliable electronic latching and locking solutions. These independent electromechanical latching devices, designed for a variety of heavy-duty and light-duty applications, allow you to integrate electronic access convenience into your equipment while maintaining a wide range of control over implementation and access methods. Because they operate on simple low-voltage electrical signals from any compatible power source, they allow you to implement whatever degree of sophistication or simplicity you desire in your access control system. And that can make electronic access an affordable option, even in low-volume or standalone applications.
The electronic systems used to control access and generate the signals needed to actuate the latches can range from a simple key fob or proximity button all the way up to sophisticated biometrics access technology. And in locations where employees already carry ID cards with mag-stripe, proximity chip, or other electronic ID technology, you can take advantage of that existing infrastructure to manage and monitor electronic access to equipment and enclosures fitted with electromechanical latches. In those instances, unique access codes on individual cards can also be used to restrict access to pre-authorized individuals (managers, technicians, etc.), to provide an electronic record of when, where, and to whom access was granted, and even to actuate video monitoring whenever access is provided.
Multiple Physical Formats
There are multiple physical format options for electronic access security. They can include manually actuated latches where an electronic signal is used to release an internal locking mechanism that keeps the external manual handle from rotating when the unit is locked. Or they can be electromechanical latches where an actual rotary latch mechanism is directly actuated by the electronic signal, allowing the door to open. These mechanisms can be constructed from metal or engineered plastics to satisfy different levels of security and cost effectiveness.
One such electronic access mechanism is the Southco E-Keeper (above left), an electronic keeper that can engage a frame or lip on a door, or be combined with a traditional mechanical latch to provide more convenient hands-free access, yet still offer manual keylock access in the event of power loss or malfunction. This easy-to-install solution is small enough and versatile enough to be retrofit into existing enclosure applications currently using mechanical latch access only.
There is also another version of access control that uses electronic signals not to actuate a locking mechanism but to monitor the status of a manually operated lock. This switch-lock hardware works like a mechanical latch with keylocking capability, but it is equipped with a relay switch that can signal a locked/unlocked condition. The signal generated by the switch lock can be used to power an indicator light on a control panel, to control lockout or interlock devices, or to complete a circuit that enables another electronic function.
If you believe that your applications could benefit from the convenience and flexibility of electronic access security, look for a latch supplier that can evaluate your needs and offer multiple solutions for saving time and money.
