Banner VALU-BEAM Series - Manual (Page 17)

Memory Backup ("MB") option: SMA990 Series sensors with internal memory backup for maintaining "count memory"
are available by special order. These models, which will "hold" a count for over 100 hours, are indicated by the model suffix "MB"
(example: the memory backup version of model SMA990LV is "SMA990LVMB"). Contact the factory for availability and
pricing on these models.
Quick Disconnect ("QD") option: The VALU-BEAM QD option allows quick and easy removal or replacement of
VALU-BEAM sensors in the field. QD option VALU-BEAM 990 Series sensors have a 3-pin male connector, built into the
sensor's base, which mates with the model MBCC-312 3-conductor female SO-type quick-disconnect cable (one wire goes
unused). To specify the QD option on a sensor, simply add the letters "QD" to the end of the sensor's model number. (Example:
the QD version of the SMA990FMB is "SMA990FMBQD".) Model MBCC-312 SJT-type cable (12' length) must be ordered
separately. See drawings, page 18.
30-foot cable option: Standard VALU-BEAM sensor models (non-QD types, which are normally supplied with a 6-foot long
PVC-covered cable), may optionally be supplied with a 30-foot PVC-covered cable. Thirty feet is the most readily-available
length; lengths longer than 30 feet may also be quoted.
Accessory Mounting Bracket model SMB900: Accessory mounting bracket model SMB900 has curved mounting
slots for versatility in mounting and orientation. The sensor mounts to the bracket by its threaded base, using a jam nut and lock-
washer (both included). The bracket accommodates both standard and "QD" sensor models. Bracket material is 11-gauge zinc-
plated steel. The curved mounting slots have clearance for 1/4" screws. See drawings, page 20.
Accessory Mounting Bracket model SMB30SM: This is a swivel mounting bracket. The base of the VALU-BEAM
sensor threads into the bracket's captive swivel ball, which is then held firmly in the desired position when the bracket's two
mounting bolts are tightened.

Fiberoptic sensing is often the
answer when, due to space or
environmental limitations, the
sensor itself cannot be placed
at the actual sensing position.
This sensor's powerful modu-
lated infrared beam is com-
patible with all Banner glass
fiber optics in the opposed,
retroreflective, and diffuse
sensing modes. Glass fiber
optic selection information
may be found in the Banner
catalog. The sensor/fiber in-
terface is waterproof to main-
tain complete sensing system
moisture rejection.
Opposed mode fiber optic
sensing is often employed in
parts counting applications.
Fiber optics can be built with
sensing ends having windows
that conform to the size and
profile of the part. This allows
most efficient use of the
sensor's emitted light energy.
Refer to the Banner product
catalog for more information.
