L300

The robust L300 safety locking devices for safety applications up to PL e / SIL 3 are used for safeguarding safety doors on machines and systems. Complete safety functions are easy to implement with the integrated command and emergency stop buttons. Using modern RFID technology, the L300 series offers maximum protection against manipulation (type 4 according to EN ISO 14119) and is easy to integrate. With a locking force of up to 9750N and the robust metal housing, the devices are particularly suitable for use on heavy doors and in tough environments.

Advantages for you

Optimum protection against manipulation: Thanks to the RFID-coded actuators. Extra installation measures are therefore no longer necessary
Securely locked doors: With a locking force of up to 9,750 N, doors remain securely locked even under extreme loads
Easy integration into a safety circuit: Thanks to their OSSD safety outputs, all devices can be easily integrated into a safety circuit
Easy installation: Integrated command and E-Stop buttons, matching door handles and the lockout-tagout functionality enable complete safety functions to be easily installed at safety doors

Highlights

Complete guarding with just one device

The optional command buttons of the L300 safety locking device simplify the setup of safety functions at safety doors. With the integrated buttons for request, reset and emergency stop, the compact device provides a complete solution for the safety system installation at an access door. This simplifies wiring and saves space.

Designed for reliable operation

The joint at the actuator and the large, chamfered opening on the device minimize the risk of collision between the sensor and actuator and prevents damage even with imprecisely closing doors. The unobstructed opening allows accumulated dirt to be simply pushed out on the rear side. The special design thus guarantees maximum reliability and availability.

Escape unlocking with panic button

The optional escape release button (panic button) enables the actuator to be unlocked immediately and the door to be opened from inside the danger zone. The ergonomically optimized button allows the operator to then leave the danger zone if he is inadvertently locked inside. The device also functions if the power supply fails.

Door handle and lockout-tagout

The AC-L300-SH adjustable door handle, which can be mounted on the right or left, ensures quick and easy installation of the L300 safety locking device on swing doors and sliding gates. The extremely robust metal construction supports the benefits of door centering by means of the joint on the actuator. The AC-L300-SH2 door handle offers a design-optimized alternative (see the illustration at the bottom of page 17).

The optional lockout-tagout device prevents operating personnel from being locked inside the danger zone by using individual padlocks. For this purpose, the safety mechanism is pushed downward and the lock inserted. This mechanically locks the opening and additionally shields RFID detection of the actuator.
