Hinged-shaped safety switches in stainless steel HX series
Pizzato Elettrica has recently introduced its new HX series stainless steel safety hinged switches.
Thanks to the use of AISI 316L stainless steel and to the accurate surface finish, this new range of devices is suitable for any environment where chemical and corrosive agents are found or for aseptic environments where particular attention is required for cleanliness and hygiene (i.e. pharmaceutical sectors, chemical or marine sector).
These are the main features of the HX series:
- AISI 316L stainless steel housing
- Protection degree IP67 and IP69K
- Intervention point 1.5° adjustable ±1°
- Versions with rear cable and rear cable with M12
connector
- Laser marking on the product
HX
series stainless steel safety switches are available both with mechanical and
electronic contact blocks.
MECHANICAL CONTACT BLOCK VERSIONS
Two versions of the stainless steel safety switches with mechanical contacts are available:
- 2NO+2NC, slow action closer with positive opening
- 2NO+2NC, slow action overlapped with positive
opening
ELECTRONIC CONTACT BLOCK VERSIONS
One
version of the HX series switches with an electronic contact block is available
with the following features:
- 2 safety outputs PNP, 1 auxiliary output PNP, 2 safety
inputs PNP.
- Possible connection in series of several
hinge-shaped safety switches: the redundant internal structure of the HX
hinged safety switch meets the characteristics required by the EN ISO
12489-1 and IEC 62061 standards, therefore the actual switch can be
classified as a device of category 4, PL e and SIL 3. HX hinge switches
can be used in series, while maintaining the PL e, as long as they are
connected to an appropriate Pizzato Elettrica safety module controlling
the correct functioning.
- 4 status-indicator LEDs: the version with electronic
contacts in the HX series is provided with 4 LEDs which make it possible
to quickly identify the status it is found in. Each LED is assigned a
specific signaling function which makes it possible to immediately
identify any wiring errors or circuit breaks. This avoids the need to
decode troublesome blinking sequences in order to identify specific system
faults.
