BENEFITS
• Standard mounting and characteristics
• Globally available and accepted
• Welded NC contacts will separate – vital
security in safety applications
• Range of actuation methods for
detecting safety conditions in guarding
and machine status applications
• Wiring and body flexibility
• Suitable for inductive switching and
safety relay interfaces
• Signalling and power/safety circuits may
be different polarities or voltages
• Immediately recognisable in the
application as a safety component
GSS Series products may be used alone as Category 1 per EN 954-1 safety component. In conjunction with other safety switches and our complete range of safety
control modules, it is possible to construct comprehensive protection schemes
with Category 2, 3 or 4 compliance per EN 954-1.
Honeywell’s design experience has resulted in a brand new patented concept in
safety switching techniques. The sequential safety switch incorporates positive
opening on the downward stroke of each NC sequence point. This allows the user to
have both a warning signal and a stop signal. With this information a door can be
closed before it stops a machine or settings adjusted to stop excessive movement
thus avoiding down time.
LOW ENERGY SWITCHING
In today’s demanding age of low energy controls, electromechanical switches are
frequently used to interface directly with safety relays, PLCs and other low energy
devices. To accommodate this requirement GSS offers gold plated contact versions
of the standard basic switch. This improves reliability of switching at low currents
and voltages, by protecting the contact surfaces from contamination during operation or storage prior to use.
Standard silver contacts have a disadvantage in that the contact surface may tarnish under certain environmental conditions e.g. in the presence of moisture.
Low energy basic switches are rated as follows:
