Frequently Asked Questions

Linea E-Lock combines the low-height Linea twin-wheel design with an integrated, programmable electronic central locking system. Depending on the configuration, it can provide directional lock, total lock and free mobility, with each switching position controlled electronically. The system removes the need for conventional steel bars and foot pedals, supporting low-effort operation, quiet switching and flexible integration into healthcare equipment.

Linea E-Lock replaces the mechanical actuation used by a conventional central lock with an integrated electronic locking system. Steel bars and foot pedals are no longer required, and each switching position can be controlled individually. This reduces the need for switching force and torque, supports programmable or contact-free operation and gives designers greater freedom when developing beds and other applications.

Linea E-Lock reduces physical effort by controlling the locking functions electronically rather than through foot pedals, steel bars or other mechanical linkages. Switching forces and switching torque are therefore no longer required from the operator. Locking positions can be selected through the configured control system, helping staff operate heavy or frequently moved equipment with less repetitive physical effort.

Effortless locking with Linea E-Lock comes from the integrated electronic actuation of the locking functions. Operators do not need to apply the force or torque associated with a mechanical pedal system, and each switching position can be controlled individually. Depending on the integration, commands can come from an operating panel, Bluetooth, radio or an app, making routine locking easier to incorporate into the workflow.

Linea E-Lock supports manoeuvrability by combining free swivel movement with selectable directional locking. In free mobility, the twin-wheel design can turn easily, while the differential effect helps movement in narrow spaces. Directional lock can then support controlled steering around bends and straighter travel over longer distances. Electronic control allows the required switching position to be selected without using a mechanical pedal.

Linea E-Lock can provide secure standing through its total-lock position, which locks both the wheel and the swivel bearing. The electronic system allows this position to be selected as part of the configured control logic. For additional safety concepts, a customer-provided movement sensor can be programmed to activate the lock automatically, helping reduce the risk of the application being left unintentionally free to move.

Linea E-Lock can support up to three switching positions: directional lock, total lock and free mobility. Directional lock helps guide the application during manoeuvring and longer straight runs, while total lock secures both the wheel and swivel bearing for stable standing. Because the positions are electronically controlled, each can be selected individually according to the programmed operating concept of the application.

Linea E-Lock can support authorised locking through customer-programmed admission control. The system can be configured so that only an authorised person is able to lock or release the castors. Because the control logic is programmable, access can be linked to the operating concept of the application. The required authorisation method and programming are defined by the customer during integration.

Yes. Linea E-Lock supports contact-free operation, which can help improve hygiene where users want to avoid repeated contact with pedals or mechanical controls. Its electronic controls are freely programmable and can be operated via Bluetooth, radio or an app. The exact contact-free control method depends on how the customer integrates and programmes the system into the application and its operating concept.

Linea E-Lock uses electronically controlled switching, avoiding the pedal-operated mechanical actuation found in conventional central locking systems. This supports quiet locking and is associated with a particularly low level of mechanical wear. In healthcare applications, the reduced switching noise can help improve patient comfort, while the elimination of steel bars and pedals also simplifies the mechanical locking arrangement.

Linea E-Lock offers flexible electronic control options. Its control function can be integrated into existing operating panels, while the controls are freely programmable and can also be operated via Bluetooth, radio or an app. Customer-defined functions can include authorised access or automatic locking using a separately provided movement sensor. The exact control arrangement therefore depends on the application and its operating concept.

If power is lost, Linea E-Lock can be unlocked manually using the emergency-release button. Turning the button 90° clockwise manually releases the directional lock, while turning it 90° anti-clockwise releases the total lock. Once power is restored, the emergency release can be reset automatically during the motor's reference run if this function has been programmed by the customer as part of the control system.

Linea E-Lock can be integrated into existing operating panels, but the control logic and electrical interface need to be planned as part of the application. The controls are freely programmable, allowing the required locking positions and user functions to be assigned to the panel. The 24 V DC supply and serial interface must be accommodated, while functions such as admission control or movement-sensor locking require customer-side programming or components.

Linea E-Lock is well suited to medical stretcher applications because it combines electronic directional and total locking with low-effort operation. Staff can control the castors digitally instead of reaching for pedals, supporting easier manoeuvring and secure positioning. Its quiet switching can also contribute to patient comfort, while contact-free or sensor-based control concepts can be integrated where appropriate for the stretcher design.

Linea E-Lock requires a 24 V DC supply, with a maximum motor current of 1.6 A. Electrical connection is via connector 03R-JWPF-VSLE-S. Its three connections are VDD for positive power, IO for the one-wire serial interface, and GND for the supply and system ground. When integrating the castor, the application power supply and control system should be designed to match these requirements for reliable operation.

Linea E-Lock has protection class IPX4, providing protection against splashing water. This can support use in environments where routine cleaning and incidental water exposure are relevant, but IPX4 should not be interpreted as protection for immersion or every high-pressure cleaning method. The overall suitability also depends on the selected castor version, fitting-area sealing and the cleaning process used on the complete application.

When using movement sensors with Linea E-Lock, the sensor needs to be integrated into the customer’s control concept and programmed for the required locking behaviour. A motion sensor can be added so the castors lock automatically after a defined period, helping improve safety for patients and staff. The timing and trigger logic should be matched to the application so automatic locking supports normal operation without disrupting manoeuvring.

The EC installation declaration for Linea E-Lock references DIN EN ISO 12100 for machinery safety and risk reduction, DIN EN 60601-2-52 for medical beds, and DIN EN IEC 61000-6-2 and 61000-6-3 for electromagnetic compatibility. It also references DIN EN 12531 for hospital bed castors. The declaration additionally cites the Machinery Directive 2006/42/EC and the EMC Directive 2014/30/EU, covering the applicable safety and EMC framework.
