HS Range - Mechanical Hinge Switches
The HSM (Die Cast) and HS-SS (Stainless Steel 316) Hinge Switches both have a mirror polished finish and are designed to be mounted for interlock position sensing of hinged moving guards.
Designed to be fitted to the hinged axis of machine guard doors and provide a robust hinge function in addition to interlock position sensing.
Positive opening contacts in accordance with IEC 60947-5-1 and after fitting the switch offers a very high degree of anti-tamper.
Used to mount the machine guard door into the machine guard frame and contact blocks are available in slow make/break 3NC 1NO, or 2NC 2NO.
Enclosures are protected to IP67 / IP69K with a low profile, hygienic design for wash-down.
Operation of the switches is achieved by the rotating action of a cam and actuator to cause deflection of the switch plunger.
Positive actuation of the contacts is achieved at only 6 degrees of opening of the guard and can be adjusted up to 12 degrees if required upon installation.
HS-Z Range - Electronic Hinge Switches
The HSM-Z (Die Cast) and HSM-SS-Z (Stainless Steel 316) Intelligent Series Hinge Switches have been developed to provide and maintain a high level of functional safety.
Will connect to most popular standard Safety Relays to maintain a PLe Safety Level even with switches connected in series. A maximum of 30 switches can be connected in series.
Easy to understand LED diagnostic functions and provides auxiliary outputs for extra diagnostic signals to PLCs or computers.
Designed to be mounted for interlock position sensing of hinged moving guards and designed to be fitted to the hinged axis of machine guard doors to provide a robust hinge function in addition to interlock position sensing.
Enclosures are protected to IP67 / IP69K with a low profile, hygienic design and is perfect for high pressure, high temperature wash-down with detergents.
The HS-Z hinge switches must be used in combination with a dual channel safety control device e.g. Safety Relay or Safety Controller. They can provide protection to Ple/Cat.4 to ISO 13849-1, and will maintain Ple with other Idem Z-type switches connected in series due to internal test functions of the switches. In addition, each switch provides input, output and guard state LED’s.
Operation is achieved by the rotating action of an enclosed cam profile and sensing components within the switch.
These hinge switches can be adjusted upon installation to provide guard-open output signal anywhere between 0 to 10 degrees.
All HS-Z switches are factory set to provide the guard open output signal at 3 degrees. Once set during installation the HS-Z is permanently pinned in order to provide a fully tamper-resistant switching point.
