Electronic Safety Guarding
Engineered Safety Systems
Safety Light Curtains
A presence sensing device, Keyence and Allen-Bradley as our primary brands, used to create a virtual barrier around at a hazardous location. These light curtains, and mirrors if needed, are designed for standard and blanking, as well as muting technology application needs using safety controllers to provide monitoring of the proper safety redundancy checking in both manual and auto reset conditions depending on the specific type of operator access.
Safety Laser Scanners
With Keyence safety laser scanners, defined as a low-profile programmable presence sensing safety unit programmed to scan a 27.5' range in a 190-degree radius in a 2D plane to detect foot traffic located in hazardous areas, blind spots, or danger zones, we can provide another level of protection while using a safety relay for redundant safety checks. Increased resistance to dust and debris, as well as a built-in cameras can be added for data collection for operational or quality needs.
3D Safety Radar
This Inxpect smart sensor branded device is a multi-zone radar technology device for safety-rated restart prevention, access detection, and anti-collision applications, covering up to a 9m area at 100-degrees horizontally and 20-degrees vertically looking for moving object(s) large enough to be a person thru radio signals. Susceptible to dust, chips, fog, oils, water/rain, particulates, shavings, default to sense movement of large objects.
Safety Switches
Allen-Bradley non-contact interlock switches, low-profile, RFID technology using inductive and coded values avoiding tampering with as magnetic sensors are and allowing for a tolerance of misalignment in standard machine guard doors, used to be integrated through a safety relay to assist in achieving desired safety category levels. Typical integration is tied to emergency stop circuits or machine signal stops with dynamic braking functions and provided with all the required cables, adapter brackets, and tamper-resistant hardware.
Door Locking Safety
A system engineered to keep the door closed using a Keyence safety interlock switch, using RFID technology for the locking solenoid to keep guard doors closed until the machine reaches a safe stop state triggered by an operator signal at a custom panel, achieved through a feedback signal using an EMF relay, amp clamp, programmable drives, PLC, a safety-encoder to detect zero-speed, or add a programmable timer-based circuit through a safety controller.
Safety Switch Mats
An ASO Safety, Recora Safety, or Pinnacle Safety pressure sensitive mat with a built-in electronic signal to detect the presence of someone standing on it, which triggers a stop behavior on a machine, such as an emergency stop signal. Custom sizes, shapes, and material types with trim kits for bolting to the floor and avoid trip hazards, along with specific wiring locations that can be created for specific applications used in conjunction with an Allen-Bradley safety controller specific to the associated safety mat.
Trapped-Key Interlock Safety System
An Allen-Bradley trapped key interlock switch provides a safety infrastructure using a logic series of keys and locks consisting of an initial key deactivating the control power removing or isolating the present hazard along with a group of mechanical keys throughout the process of accessing the controlled area. This system requires no field wiring beyond the key at the control source. Configurations to include single operator access to multi-user key exchange panels and deadbolt latches.
PowerControls Safety Enclosure
A PowerSafe, pre-configured, isolated safety enclosure, pre-wired to a power supply, and the required safety relays or safety controllers to properly monitor the redundancy checking of the e-safety devices, such as light curtains, safety switches, and safety laser scanners, used in your machine safety system. Devices are wired to this enclosure, then a trigger wire to the machine controls to simplify interconnections and troubleshooting with associated schematics.
Custom Safety Enclosures
A NEMA enclosure designed and built to proper fit size and shape for additional options such as 1:1 switch to safety relay, safety controller, or safety PLC notifications monitoring the state of each safety devices at the associated entry point of the machine guarding, added air logic components, upgraded functionality for safety, cabinet coolers, and stack lights.
Press Safety Light Curtain System
Protech Systems brand solution uses a point of operation and area guarding devices providing protection on presses with manual or automated processes, which may be require control systems upgrades as part of the package. These systems are used in conjunction with physical machine guards, and safety laser scanners. Upgrades may also include die blocks, power cutoffs, and wedges for optimal protection of your presses.
Press Die Blocks with Safety Interlocks
Power series die blocks, or ram blocks used to support a die from overhead creating a crushing hazard through unexpecting drifting or falling. These devices cover a range from 35 to 125-ton static load, adjustable from heights of 9" to 36", to include safety interlock connection to ensure die block is being used during setup or maintenance.
