• Non-contact safety switches
• Solenoid locking RFID tongue interlock safety switches
• Tongue interlock safety switches
• Hinge interlock safety switches
• Cable-pull safety switches
• Emergency stop control stations
• Accessories

Fail-safe Inductive Sensors

New!

Fail-safe inductive sensors are specialized proximity sensors with an OSSD output for connection to a safety relay. They allow for the detection of metal objects in safety applications.

• 12mm, 18mm, and 30mm tubular, and large rectangular models
• (2) OSSD outputs
• Flush and/or non-flush mount, depending on model

Safety Controllers

Safety controllers are modular and configurable for managing all safety functions of a single machine or an entire plant that offers cost reductions with minimal wiring. Master modules are available as standalone units or units with expansion capabilities.

• 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 Configurable Relays

New!

Safety configurable and programmable relays reduce the number of individual safety relays required to properly monitor machine safety equipment. Configurable relays are available to support several different applications, and programmable relays can be used to replace up to 8 safety relays. Both types of devices are easy to use and require no programming experience.

• Configurable relays
• Programmable relays
• Safety extension relay

Safety Relay Modules

Newest Additions!

• Dold safety relay additions including more E- stop relays, light curtain control relays, and speed and motor standstill monitoring relays

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 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 ensure safety on any surface at potential crushing or shearing points. They are 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

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 for up to three gates
• Push-pull trap key systems for up to five gates
• Easy installation through comprehensive accessories

Two-Hand Controls

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

• Aluminum and plastic panel enclosures
• Zero-force pushbutton option
• Available with or without pushbuttons

Safety Enabling Switches

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.

• The three-position, spring-return button must be held in the middle position, ensuring the machine will shut off, even if the operator's hand is pinned
• 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

IEC Safety Contactors

Safety contactors provide a safe and reliable way to control electrical power in industrial and commercial applications. IEC safety contactors feature mechanically-linked and mirror contacts to provide safe operation of machines and equipment.

Mechanically-linked contacts ensure that normally open and normally closed auxiliary contacts can never be closed simultaneously. Mirror contacts offer a way for safety circuits to reliably monitor the status of the main contacts.

Machine Guarding

Using physical barriers to limit access to dangerous areas is a primary means of protecting workers and machinery. Machine guarding components can be installed quickly, and their various sizes allow for flexible design options.

• Carbon steel open-grid panels
• Hinged and sliding doors
• Posts
• Mounting hardware

Gate Boxes

Gate boxes provide high-level RFID-coded interlocking, tamper-proof guard locking, and machine control in one unit. Models with rear escape handles prevent personnel from being trapped in a guarded area.

• Universal gate boxes
• Gate box accessories
