AC motor starters are used to turn-on and turn-off electric motors and motor-controlled equipment. They use solid-state or electromechanical technologies, and are designed for single-phase or three-phase motors.
|
|
Cable assemblies are collections of wires or cables banded into a single unit with connectors on at least one end.
|
|
Circuit breakers are mechanical switching devices capable of breaking currents under specified abnormal circuit conditions.
|
|
Computers are programmable electronic devices that accept data, execute prerecorded instructions, perform mathematical and logical operations, and output results.
|
|
Control panels are used to receive inputs, trigger outputs, and monitor systems and instrumentation. They are used in a variety of industrial, manufacturing and process control applications.
|
|
Counter and timer boards are computer cards that perform digital counting and/or timing functions.
|
|
DC motor starters combine a controller (most often a contactor) with overload protection, allowing a motor or motor-controlled equipment to be turned on and off.
|
|
Electrical connectors are devices that join electrical circuits together. Male connectors plug into receptacles, jacks, and outlets. Female connectors contain sockets to receive other devices.
|
|
Fuse holders are devices for containing, protecting and mounting fuses. Blown fuses can be changed quickly and easily when used in conjunction with a fuse holder.
|
|
Fuses protect electrical devices and components from overcurrents and short circuits that occur in improperly operating circuits.
|
|
Industrial computers are similar to personal computers (PC), but they are intended for use on a factory floor or in other harsh environments.
|
|
Light curtain controllers send stop signals to machines that are guarded by light curtains, photoelectric transmitters that project an array of synchronized, parallel infrared light beams to a receiver.
|
|
Light curtains are photoelectric transmitters that project an array of synchronized,parallel infrared light beams to a receiver unit. When an opaque object interrupts one or more beams, the light curtain controller sends a stop signal to the guarded machine. Light curtains are used as personal safety devices around hazardous machinery or for permiter guarding.

|
Mechanical safety interlock switches couple a moveable guard door with the power source of the hazard. When the guard door is opened, the power is isolated, ensuring that the machine does not pose a hazard while an operator requires access.
|
|
Motor contactors are relays with large current capacity for connecting and disconnecting a motor from the power supply. Typically, motor contractors are multi-pole for control of all current carrying conductors.
|
|
Motor starters and contactors are motor-starting devices. They combine a contactor with overload protection and are designed for starting AC or DC motors.
|
|
Noncontact safety interlock switches couple a moveable guard door with the power source of the hazard. For noncontact actuating interlock switches, the guard door is linked to the control circuit contacts via a magnetic or electronic field.
|
|
Panelboards and switchgear are electrical distribution devices that convert incoming electrical power into several smaller circuits and provide overload protection in the form of fuses or circuit breakers.
|
|
Power or line conditioners regulate, filter, and suppress noise in AC power for sensitive computer and other solid state equipment.
|
|
Power supplies are devices that produce AC or DC power. This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters.
|
|
Pushbutton switches are mechanical switches defined by the method used to activate the switch. The activation method is typically in the form of a plunger that is pushed down to open or close the switch.
|
|
RF couplers are circuits that sample RF transmissions by combining (coupling) signals asymmetrically. There three basic types of devices: unidirectional, bidirectional, and dual directional.
|
|
Safety mat controllers monitor areas where injury is possible due to moving mechanical parts or other similar hazards. When pressure is detected on a mat, a stop signal is sent to the surrounded machine.
|
|
Safety mats are presence-sensing devices used to guard a floor area around a machine or robot.
|
|
Safety relays and control modules differ from conventional relays in that they have force-guided or positive-driven contacts.
|
|
Safety sensors are used for machine safeguarding. Types of safety sensors are break-a-beam switches, interlocks and tag out devices, perimeter guards, photoelectric safety sensors, safety blocks, safety interlock switches, and safety sensor switches.
|
|
Signal conditioning products provide amplification, filtering, converting, and other processes required to make sensor output suitable for reading by computer boards.
|
|
Signal transformers transfer information from one circuit to another by electromagnetic induction. They are used to increase or decrease the voltage from one side of a power transformer to the other.
|
|
Single phase uninterruptible power supplies (UPS) sit between an AC outlet and an electronic device to provide power conditioning, back-up protection, and distribution for electronic equipment loads. They also prevent power disturbances from affecting the performance and life of the electronic device and vital data.
|
|
Specialty timers are specialty or proprietary products related to timers and timing devices.
|
|
Speed controls, including speed regulators and rate controllers, are used to decelerate and regulate the speed of loads such as moving carriages and machining feeds near the end of their travel.
|
|
Surge suppressors are used to protect equipment from transient overvoltages in power, data, and telephone circuits.
|
|
Switches are used to allow electric current to flow when closed. When opened, they prevent current flow. Common switch types include pushbutton, rocker, toggle, rotary coded DIP, rotary DIP, key lock, slide, snap action, and reed.
|
|
Terminal blocks are modular, insulated blocks that secure two or more wires together. Terminal blocks consist of an insulating body and a clamping device. Their flexibility allows wiring to be centralized and makes it easier to maintain complex control circuits.
|
|
Three phase uninterruptible power supplies (UPS) operate in conjunction with existing electrical systems to provide power conditioning, back-up protection, and distribution for electronic equipment loads that use three-phase power.
|
|
Transfer switches transfer electrical power back and forth between two power systems or buses such as a utility power line and a backup motor-generator power supply.
|
|
Uninterruptible power supplies (UPS) are backup batteries that provide emergency power to electrical systems in case power becomes unavailable. They are connected between a power source (such as an electrical outlet) and the equipment to protect (such as a motor or computer).
