Machine Safety

Hazardous Area Devices

Hazardous location safety devices are designed to be used in a hazardous location. They operate just like traditional safety devices but are designed to be able to be used in hazardous areas. Hazardous area safety devices available include:

• Cable-pull switches
• Safety limit switches
• Tongue interlock safety switches

Intrisically Safe Isolators and Barriers

Newest Additions!

• More digital, analog, and temperature modules; new frequency isolators and a zener barrier for thermocouple signals

Isolating barriers provide intrinsic safety and galvanic separation between the control system and the field device.

• Dual-channel models available for all circuit types
• Digital, analog, frequency, and temperature modules available
• Digital and analog modules are rated for SIL applications
• Intrinsically safe zener barrier for thermocouple signals available
• Configuration kit available for temperature and frequency modules
• The pac-Bus connection system saves time and wiring by allowing multiple modules to share a common power source

Safety Laser Scanners

Area scanners are an intelligent and cost-efficient way of protecting a zone or area by using lasers in a 275-degree viewing window.

• Operating ranges of 3 and 5.5 meters available
• A great choice for fixed installations as well as mobile applications such as AGVs
• Configurable I/O, dust filtering, warning areas and warning signals all completed through the unit's GUI

Safety Controllers

Safety controllers are modular, expandable and configurable for managing all safety functions of a single machine or an entire plant that offers cost reductions with minimal wiring. Master modules can be used stand-alone or with additional expansion modules.

• Reduces number of devices and wiring used and overall size of the project
• Speeds up control panel construction
• Allows tamper-proof system configurations
• All logic is configured through a graphic interface
• Lowers the number of electromechanical components for a better performance level and a higher safety level

Safety Relay Modules

Newest Additions!

• More motor standstill safety relays and relay extension modules

Safety relays are coils and contacts designed to be positively driven and assure a reliable opening and closing for machine safety applications. They are developed and manufactured according to IEC and EN European standards and are RoHS, CE and UL Listed. These modules consist of safety relays controlled by built-in monitoring functions.

• E-stop / safety gate relays with one or multiple channels
• Two-hand control relays
• OSSD / light curtain relays
• Safety mat and edge relays
• Speed / standstill relays
• Multifunction, extension and force guided relays

Safety Mats

Safety mats are used to protect people and machinery from harm. Mats detect the presence of personnel on horizontal surfaces (usually the floor). Mats are wired to specialized safety relays for fail-safe triggering of the intended safety function.

Types available include:

• Tapered edge
• Straight edge
• Diamond plate

Safety Edges & Bumpers

Safety edges and bumpers are pressure-sensitive devices used to safeguard equipment from damage and prevent injury to personnel.

Edges can be used on any surface to ensure safety at potential crushing or shearing points; commonly used on the edges of automatic gates and doors.

Bumpers are used in applications involving vehicles or other moving equipment. Both edges and bumpers are wired to specialized safety relays for fail-safe triggering of the intended safety function.

Trapped Key Interlock Switches

Newest Additions!

• Rotary trapped key switches

Trapped key systems ensure that power is removed before any access can be gained to a dangerous machine or specific hazard through gates or doors. They are available in either standard or solenoid-locking versions. All keys and their corresponding receivers and modules are identical within a set, but unique to any other set.

• Rotary trap key systems available in one to three gates
• Push-pull trap key systems available in one to five gates
• Easy installation through comprehensive accessories

Two-Hand Controls

Two-hand control systems are used with a control monitoring relay, and require an operator to use both hands at the same time when initiating a hazardous operation.

• Aluminum and plastic panel enclosures
• Available with or without pushbuttons

Safety Enabling Switches

New!

Enabling switches, also called "hold-to-run" or "dead man's" switches, provide operators with a special control mode when performing tasks such as maintenance or debugging of hazardous equipment. These handheld switches must be maintained properly by the operator for the equipment to function.

• Three-position spring return button ensures that even if the operator's hand is pinned the machine will shut off by requiring the button to be actively held in the middle position at all times.
• Robust IP67 housing
• Optional increased protection against manipulation with in-hand detection
• Models with built-in E-stop, LED, pushbuttons, and activity ("home" position) sensor
