For extremely loud environments, these headsets have noise-canceling ear muffs and an adjustable-volume microphone.

CB radios use nonbusiness designated frequencies and do not require a FCC license.

Also known as walkie talkies, these radios work best at short distances in areas with little to no obstructions.

These intercoms are rated for environments where hazardous material is present.

These headphones have an extra-wide headband and padded ear cushions for all-day comfort.

Make hands-free calls from your computer, laptop, smartphone, or other device.

Use these phones to connect with off-site colleagues.

DECT (Digital Enhanced Cordless Telecommunications) technology keeps these phones from experiencing interference with other devices, including wireless computer networks.

Amplify weak cellular signals, resulting in fewer dropped calls and faster download speeds.

Replace a broken plug or create your own wall cord using telephone cable.

Connect two telephone cords together to create a longer cord.

Attach these tangle preventers to your handset and cord—they allow the handset to rotate freely so the cord won't get tangled.

Combine the functionality of a PLC and the accessibility of a development board. Built around a Raspberry Pi and an Arduino-enabled microcontroller, these controllers use open-source software to make programming and troubleshooting convenient.

Design and operate up to six simultaneous programs without symbols or technical language—the on-screen instructions use simple English.

No need to program multiple PLCs—these modules expand your automated system, keeping everything conjoined and configured on one processor. Use them when you’re out of space on your DIN rail or need additional input/output functions.

Link industrial equipment with multiple computers to expand your data network.

Mount these Ethernet switches to DIN rail to bring connections closer to where you need them.

Scan and sort RFID-tagged inventory, track RFID-tagged items around your facility, and control building access. Unlike bar code scanners, these readers/writers can scan multiple tags simultaneously without direct line of sight.

Generate an audible signal when testing for short circuits and line continuity, or to locate a cable.

Send data between computers, servers, and switches in an office or workstation.

Also known as plenum cable, this cable has low-smoke insulation and can be used without conduit in ductwork and above a drop ceiling. Use it to send data between computers, servers, and switches.

Also known as plenum cable, this cable has low-smoke insulation and can be used without conduit in ductwork and above a drop ceiling. It has an oil-resistant insulation to protect wires as the cable moves from duct to equipment or machinery.

Connect devices such as sensors, programmable logic controllers, and actuators to an automated network.

This cable has twisted pairs of wires that cancel signal interference from multiple transmission lines. Use it for complex and high-speed data and signal transmission.

Connect low-current circuits such as intercoms and security systems to a building's electrical system in single-level facilities.

This cable has an uninsulated ground wire that touches the protective metal armor so it can be used for bonding and grounding. It's often used along the exterior of walls to carry power to outlet boxes. Also known as AC cable.

This cable is approved for use in vertical shafts and large facilities with mulitple levels for critical circuits such as fire alarms and smoke detectors.

The metal armor on this cable acts as conduit to protect the internal wires. It's often used along the exterior of walls to carry power to outlet boxes. Also known as MC cable.

Also known as plenum cable, this cable has low-smoke insulation and can be used without conduit in ductwork and above a drop ceiling. Use in critical circuits such as fire alarms and smoke detectors.

Keep water from damaging wires—this cable has a layer of absorbent material that traps moisture before it reaches the internal wires. It sends signal and data to operate, measure, or regulate automated equipment.
