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
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.

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.
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
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
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 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.
