HX BEE1-KSMH90 Pizzato Hinged-shaped safety switches in stainless steel HX series

Why Choose the Pizzato HX BEE1-KSMH90 Hinged Safety Switch?

The Pizzato HX BEE1-KSMH90 is an advanced hinged-shaped electronic safety switch from the stainless steel HX series, designed for monitoring hinged guards, doors and protective panels on industrial machinery. By integrating the safety switching function directly into the hinge, it provides effective guard-position monitoring without the need for a conventional separate actuator.

The HX BEE1-KSMH90 uses a 24 V DC electronic contact block with 2 PNP safety outputs, 1 PNP signalling output and 2 PNP safety inputs. Its redundant electronic architecture supports high-level machine safety applications and allows multiple compatible HX switches to be connected in series while maintaining a high safety level when integrated with an appropriate Pizzato Elettrica safety module.

Manufactured with an AISI 316L stainless steel housing, the HX series is particularly suitable for applications exposed to chemical or corrosive agents and for environments requiring high standards of cleanliness and hygiene. The switch provides IP67 and IP69K protection, an adjustable intervention point and an 8-pole M12 connector, while the H90 configuration provides the dedicated 90° hinge arrangement for suitable guarding installations.

High-Level Electronic Monitoring for Hinged Machine Guards

Hinged-shaped safety switches integrate guard-position detection directly into the hinge, eliminating exposed separate actuators and helping create compact, tamper-resistant machine-guarding systems. The Pizzato HX BEE1-KSMH90 electronically monitors hinge movement and provides 2 redundant PNP safety outputs for connection to an appropriate safety controller or safety module.

The electronic HX architecture also incorporates 2 PNP safety inputs, allowing compatible switches to be connected in series. The redundant internal design can support applications up to Category 4, PL e and SIL 3 when the complete safety system is correctly designed and connected to appropriate Pizzato Elettrica safety control equipment. Its AISI 316L stainless steel construction and IP67/IP69K protection make it particularly suited to food processing, pharmaceutical, chemical, marine and other demanding industrial environments.
