Ojmar OTS20 Batteryless RFID Locker Lock
The Ojmar OTS20 Batteryless RFID locker lock combines contactless electronic access with self-powered operation. Designed for commercial lockers and suitable storage furniture, it provides an alternative to conventional keyed locks and battery-powered electronic locking systems.
Using Ojmar's Push Power technology, the lock generates the electrical energy required for operation when the user presses its knob. No batteries or external electrical supply are required.
The OTS20 Batteryless is particularly relevant to leisure centres, workplaces, gyms and other organisations seeking convenient electronic locker access without routine battery replacement.
How Ojmar Push Power Technology Works
The OTS20 Batteryless uses the mechanical action of pressing the operating knob to generate the energy needed by its electronic locking mechanism. Users can therefore access their locker without the lock depending on replaceable batteries or a wired power connection.
This approach is useful where fitting electrical cabling would be impractical or where an organisation wants to reduce the ongoing maintenance associated with conventional battery-powered locker locks.
The lock remains an electronic RFID system, so suitable access credentials and any required management arrangements must still be established for the installation.
Contactless RFID Access for Lockers
Users gain access with a compatible RFID credential rather than carrying a separate mechanical locker key. Depending on the selected system, suitable credentials may include cards, wristbands or key fobs.
This can simplify day-to-day locker use in facilities where visitors, members or staff already carry an electronic access credential.
Where a site wants to use its existing membership or building-access cards, compatibility must be confirmed before ordering. A credential being described as RFID does not automatically make it compatible with every electronic locker lock.
See the OTS20 Batteryless technical specification for supported credential requirements and installation considerations.
Reduced Battery Maintenance and Consumable Waste
Battery replacement can become a significant maintenance task in facilities operating hundreds of electronic locker locks. Staff may need to monitor battery condition, maintain replacement stock and arrange access to individual lockers for servicing.
The Ojmar OTS20 Batteryless eliminates the battery-replacement element of this work, potentially reducing maintenance time and recurring consumable costs over the installation's working life.
Avoiding replacement batteries also reduces the associated battery packaging, handling and disposal. These are practical operational advantages, although the lock and its mechanical components will still require appropriate inspection and maintenance.
For organisations comparing electronic locking systems, the initial lock cost should therefore be considered alongside the maintenance requirements of the complete installation.
Where Are OTS20 Batteryless Locker Locks Used?
The OTS20 Batteryless can be considered for commercial locker installations where contactless access, convenient daily operation and reduced battery maintenance are important.
- Leisure centres and swimming pools: locker access for visitors and members using communal changing facilities.
- Gyms and health clubs: electronic locking for facilities with frequent locker use throughout the day.
- Corporate offices: contactless locker access for employees and suitable flexible-workplace storage arrangements.
- Staff changing rooms: an electronic locking option for workplaces managing substantial numbers of employee lockers.
- Spas and wellness facilities: RFID locker access for suitable changing-room environments.
- Office storage furniture: electronic access for compatible cabinet and storage-door installations.
Suitability depends on the locker construction, required access arrangement and operating environment. Particular attention should be paid to installation conditions in wet or frequently cleaned areas.
Planning a New or Replacement RFID Locker Installation
The OTS20 Batteryless may be specified for new locker projects or considered when upgrading an existing mechanical or electronic locking system. Establishing the operating requirements early can help avoid unsuitable product selection and unnecessary alterations to locker doors.
Before requesting a quotation, consider:
- Whether the project involves new lockers or an existing locker installation.
- The number of locks required and whether installation will take place in stages.
- Whether users will need new RFID credentials or use an existing access system.
- How locker access will be administered and how users will receive assistance.
- Whether the intended locker doors and environment are suitable for the selected lock.
- Whether programming equipment, credentials or installation accessories are required.
The Specification section provides the technical information needed to assess credential compatibility, fitting dimensions and environmental requirements.
