KRONENBERG contacts are silver-plated and self-cleaning. The use of high-quality materials ensures a long service life – and thus scheduled maintenance intervals.
The innovative HZTK is a safety switch with forced actuation which can be used as door switch and switch for locking mechanism. It allows a large sliding area between contact bridge and switch. In addition to the standard design (HZTK-1), a higher version is available (HZTK-2), at which the connection cables can be laid below the switch.
The door contact PZ73 is a safety switch with forced actuation and is used to control the close position of lift doors resp. as switch for locking mechanism at automatic doors.
The door switch DZ73 is a safety switch with forced actuation and is used to control the close position of lift doors resp. as switch for locking mechanism at automatic doors. The DZ73 uses the same contact inserts as the PZ73, however, has a very narrow oblong design.
The door switch with additional reed contact DZRK is a safety switch with forced actuation and is used to control the close position of lift doors. The additionally built-in reed contact offers a high protection against manipulation, as it only switches when the special contact bridge with integrated permanent magnet DZM21 is inserted.
The switch for locking mechanism for hook locks HZ is a safety switch with forced actuation and is preferably used to control the locking of the hook lock at automatic doors. The switch copes as well with longitudinal movements at small swiveling radius of the hook lock.
The door switch HZS is a safety switch with forced actuation and is used to control the close position of lift doors resp. as switch for locking mechanism at automatic doors.
The water-protected safety switch WZ with separate actuator is a safety switch with forced actuation and is used to control the close position of lift doors. It is very robust and therefore particularly suitable for lift doors. The actuator is mounted at the door leaf. When pulling the actuator out of the switch a forced opening of the contact is made.
The sliding door positive contact RZ is a safety switch with forced actuation and is preferably used to control the close position of two-part doors on service lifts and at roller shutters. The corresponding contact bridge RZ-K has a silver-plated double roller that rolls over the stationary contacts in the RZ and bridges them electrically.
The sliding door positive contact RZ-50S is a safety switch with forced actuation and is preferably used to control the close position of two-part doors on service lifts and roller shutters. The version RZ-50S is characterized by a particularly long contact travel. The actuation is made by the contact bridge, which has a silver-plated double roller for bridging the fixed contacts.
The contact bridges PZ or DZ are needed to actuate the door switches. Due to different designs and heights and by means of the pads available as option an adaptation to different installation conditions is possible.
To increase the safety of the service technicians during maintenance and repairs of lift installations, KRONENBERG offers the electrical contact bridge EKB. The EKB has two contact pins. The distance between the pins can be adjusted using a rotary wheel. An automatic pulley is used to attach the EKB to the clothing of the service technician so that the EKB cannot get lost or remain at the contact point accidentally.
