Machine Safety

The NHP range of Smart Safety Solutions are designed and engineered for effective and safe stoppage of loads when the operator head is pressed. Available in 22.5mm and 30.5mm mount operators, the E-Stop devices include both illuminated and non-illuminated options, different head types and sizes, pre-built enclosed stations, self-monitoring contact options.

The NHP Guard Locking Switches are designed for protecting hazardous areas where danger is not immediately removed after a stop request. They are ideal for use on applications such as high inertia rotating machines, fast rotating machines, and machines where high pressure is required to be released from pneumatic valves.

The Allen‑Bradley Guardmaster® smart safety devices feature GuardLink technology to deliver information and flexibility while enhancing safety and increasing machine and plant-wide efficiency. Tap to access real time, contextual diagnostics and sensor health data for troubleshooting, along with Automatic Device Reset for seamless integration into Rockwell Automation EtherNet/IP™ architecture.

NHP offers a broad range of Large Programmable controllers providing increased performance and security for the growing demands of smart machines and equipment in manufacturing. Utilising the Studio 5000® design environment, EtherNet/IP for high-speed motion applications and SIL2/PLd and SIL3/PLe safety solutions, optimises productivity and reduces commissioning time.

NHP Limit Switches are electro-mechanical devices consisting of an actuator mechanically linked to a set of contacts. When an object comes into contact with the actuator, the device operates the contacts to make or break an electrical connection. The rugged design allows the limit switches to work in a variety of applications and environments, easy to install with simple and reliable operation.

NHP offers a complete range of Mid range Programmable Safety Control Systems designed for safety-critical applications. Utilising the Studio 5000 Logix Designer® application which allows users to design and maintain systems while reducing commissioning time and managing integrated motion over EtherNet/IP™ for high-speed motion applications and up to SIL 3/PLe safety solutions.

NHP's Non-Contact Interlock Switches protects personnel and equipment while offering flexibility and productivity in the safety system.

NHP's offering of Allen-Bradley® GuardShield™ presence sensing safety devices protect personnel and equipment by detecting the presence of people and objects within a guarded area around machinery. Ideal for applications where personnel need frequent and safe access to hazardous areas such as robotic welding, machining centers, stamping, hydraulic presses, filter presses or packaging equipment.

NHP's Safety Contactors provide mechanically linked, or mirror contact, performance up to 750 A, meeting modern safety applications requirements for feedback circuits. By utilising mirror contacts they are able to provide safe isolation of hazardous motion loads while delivering reliable indication about the open or closed status of the main power poles.

NHP's 843ES CIP Safety over EtherNet/IP™ Encoders are designed for safety applications that require speed, direction or position monitoring safety functions. Supporting the GuardLogix® controller-based safety functions, according to IEC 61800-5-2 via the Studio 5000 Logix Designer® application and utilising auxiliary feedback with an EtherNet/IP network and advanced drive safety instructions.

NHP offers a broad range of Safety I/O Modules that provide a comprehensive, high-performance safety solution that is easy to install and use. Featuring a wide range of safety functions, fast response times and flexible design, ideal for industrial safety applications, offering integrated safety with systematic capability up to SC 3 (SIL 2 and SIL 3 capable) designed for fail-safe applications.

The NHP range of Safety Relays are designed to check and monitor safety systems to allow the machine to start or execute commands to stop the machine. Featuring a modular and configurable design ensuring both single-function and large safeguarding devices are catered for.

NHP's Tongue Interlock Switches offer several options for head switch rotation and are ideal for applications requiring flexibility on switch operation and guard mounting.

NHP's Trapped Key Interlock Switches provide flexible configuration to ensure a predetermined sequence of events takes place or reducing hazards prior to operator exposure.
