Type B-5003
Superior Access Interlock Unit
Printable Technical Information
Printable Access Interlock General Recommendation
The Superior Door Locking Unit, type B-5003, is an
Interlocking unit designed for either surface or sub-mounting for the
Interlocking of access doors to various equipment such as electrical cabinets,
fuse doors, transmitter cabinets, capacitor banks, access to automated
equipment, compartment or cell doors, access doors, etc. This prevents access
to enclosures, hazardous machinery, high voltage areas, automatic robotic
equipment, high or low temperature areas, chemically hazardous vessels,
dangerous gangways, compartments or other restricted areas, etc. until a key,
signifying that entry is safe, is inserted in the Interlock.
This unit is more suited for accurately aligning doors. For
poor aligning doors the Superior type B-857 or B-1496 may be considered.
An essential feature of all Superior Access Door Interlocks
is the key retaining feature which prevents the removal of the key from the
Interlock until the doors are returned to the closed position. The removal of
the key locks the door closed. The key, when removed, gives evidence that
the compartment door is locked closed.
Two co-related locking members are used to provide the
key-retaining feature. They are:
- A bolt eye or keeper
- The door Interlock Proper
In the usual installation, the Interlock is mounted on the door and the bolt
eye is mounted on the doorframe or jam. This arrangement may be reversed.
When the bolt eye is brought into engagement with the door Interlock, a
latching device within the door Interlock permits the key to be removed from
the Interlock. Turning the key projects the bolt member into the bolt eye and
locks the door in the closed position. The latching device in the door
Interlock prevents the key from being removed in any but the closed position
of the door.
The Superior type B-5003 access Interlock is available in
our standard bronze unit or with the lock cylinder totally protected by 300

A suitable compact switch element or multiple auxiliary
contacts are also available for use when it is necessary to provide additional
electrical protection, provide feedback, signal PLCs, operate indicating
circuits, or open and close other electrical circuits of the interlocked
equipment.

single key, two key, and up to six key operations, with and without auxiliary

DOOR LOCKING UNIT, type B-5003, may also be used for outdoor service, provided
that suitable dust covers are used and sub-mounting beneath the door frame or
panel is recommended.
