The Guardstar B Series
Light Curtain has been designed as a compact, intelligent unit capable
of answering current and future demands within the guarding industry.
Advanced electronics is at
the heart of the New B Series with extensive use of powerful surface-mounted
microprocessors and Guardstar’s Application Specific Integrated Circuits
(ASIC).
These engineered components
permit the compact size and sophistication of these units, allowing them
to perform many tasks, normally only possible with extensive external equipment
and complex wiring.

Flexible Interface
An emitter and receiver
pair function as a self-contained system which is capable of safety functions
without additional equipment. The interface configuration can be used with
a variety of readily available safety relay units, and fail-safe PLC’s,
in addition to a wide range of control units from Tapeswitch.
Product Range
A wide range of sizes and
specifications are available, including models for small apertures, large
access areas, and point of operation protection for fingers, hands, arms
and torsos.
Beam Blanking
Beam blanking allows the
light curtain to operate where there is a permanent obstruction in the
sensing field, such as workpiece supports. All B Series units have a built-in
“teach” function allowing them to learn from a hand-held programming unit
without additional equipment or delay. They are easily configured for fixed
obstructions. Two floating beams allow the obstruction to move up and down
within the sensing field without activating the outputs.
EN 61496 Type 4 Design
This is the highest level
of the most stringent standard in the world, acceptable and suitable for
the most dangerous of machines. CE certified and marked. (Independently
third party approved.) |
Construction
The tough one-piece aluminum
extruded body measures only 35mm (1 3/8”) x 45mm (1 3/4”) providing integrated
appearance on the machine. It’s strong enough for the toughest industrial
environments and has excellent resistance to vibration and impacts. The
use of ASIC electronics also means a greatly reduced component count for
higher reliability and simple servicing.
Solid State Surface Mount
Construction
The B Series sensing unit
is designed using state of the art surface mount technology. All of the
sensing unit components are solid state, therefore there are no moving
parts. This significantly improves both reliability and response time.
The response time of less than 15ms is independent of curtain size.
Connectors and Cables
The B Series sensing units
are equipped with quick disconnects. The receiver has an 8 pin male and
the emitter has a 5 pin male. The molded cable assemblies are keyed to
ensure that the cables cannot be inadvertently misconnected. The cables
are IP68 rated, UL and CSA recognized. The cables are offered in 15 ft.
and 30 ft. lengths and are ordered separately.
Mounting Brackets
Mounting brackets are supplied
with the B Series sensing units. The brackets can be oriented to accommodate
most installation requirements. They are designed to fit with most commonly
available structural framing systems. |
