Door interlocks

KRONENBERG door interlocks are today in service throughout the world and are installed in lifts with both swing and sliding doors. They are type-tested according to Euro Norm EN81. The KRONENBERG range of door interlocks with or without faulty closure device contains nine basic type and with the options available offers around a million possible variations.

 

DLF 1/7 / DL 1/6
standard device for single-swing doors

The standard device can be used for most of the applications. Other door interlocks are only necessary for special aims. The version DL 1/6, without a faulty closure device, can only be a part of the locking mechanism. The DLF 1/7 is suitable for a complete locking.

DLF1 / DL1
standard device with extended range of application

For more than the standard aims this device can be used for example in the case that it has to be waterproof. This device is especially suitable for equivalent application, because the positions of the electrical connections do not change. The version DL 1 without a faulty closure device can only be a part of the locking mechanism. The DLF 1 is suitable for a complete locking.

DL(F)1-EN81-21
standard device with monitoring of the emergency release according to EN 81-21

 
 Of course a version with monitored emergency release according to EN 81-21 is available.

DLF1MO / DL1MO
with actuation by electro motor

DL(F)1MO
The DL(F)1MO is operated by a three-phase motor and is an interesting alterntive to the door interlock DLF1EM with electromagnetic actuation.
Compared to the DLF1EM the attraction force of the DLF1MO is about three times higher, although the starting current could be reduced by considerable 88% and the holding current by approx. 50%. Due to the damped and flowing motion frequencies the unlocking and locking of the shaft doors are hardly audible. Also the sound insulation requirements of rooms needing particular protection are adhered to.

Door Interlocks in compact design
 

ELF1 / EL1
compact version for single swing-door

The compact design allows the application with small fitting space required. Together with adaptations also other makes can be replaced. The version EL 1, without a faulty closure device, can only be a part of the locking mechanism. The ELF 1 is suitable for a complete locking.

EL(F)1-EN81-21
compact version for single swing-door with monitoring of the emergency release according to EN 81-21

 
 With a special insertion, the emergency release can be monitored according to EN 81-21 at the door interlock EL(F)1-EN81-21.

CL(F)
compact door interlock with central placed latch bolt

By the particulary compact dimensions, the reduced forces an actuation travels it is ideally suited
for standard applications and where space is limited.

CL(F)Mo
compact door interlock with motor drive

The CL(F)MO is operated by a three-phase electric motor and has a very high starting power. The device has a small construction height and is energy saving due to the low starting current and the low holding current. Because of the damped and flowing motion frequencies the unlocking and locking of the shaft doors are hardly audible. Also the sound insulation requirements of rooms needing particular protection are adhered to.

DLF2 / DL2
for double swing-doors

The door interlock with two latch bolts is used for double doors, designed as swinging doors or sliding doors. The version DL 2, without a faulty closure device, can only be a part of the locking mechanism. The DLF 2 is suitable for a complete locking.

 Door Interlocks with higher level of protection
 

DLF 1W
water-protected version of the DLF1

To assure the waterprotection, the DL(F)1W is equipped with a sealed metal cover and a hard-chrome plated latch bolt.

DLF1MO-W / DL1MO-W
with actuation by electro motor and level of protection IP54

The motorized door lock DL (F) 1MO is now also available in level of protection IP54.
Due to the sealing against splashing water and dust the door lock is suitable for the use in harsh industrial environments.
We offer the innovative device for the vertical or horizontal operating position. All other features of the silent door lock, such as the high pull-in force,
the low pull-in current (<1 A) and the automatic switching to the reduced holding current for 100% duty cycle (<0.2 A), are of course also preserved at the IP54 version.

DLF2 / DL2
water-protected version for double swing-doors

To assure the waterprotection, the DL(F)2W is equipped with a sealed metal cover and two hard-chrom plated latch bolts.

DLF1-IP67 / DL1-IP67
increased level of protection for single swing-doors

The increased level of protection allows the application under extreme ambient conditions. The version DL 1 - IP 67, without a faulty closure device, can only be a part of the locking mechanism. The DLF 1 - IP 67 is suitable for a complete locking.
