MQTT has emerged as the preferred IIoT communications protocol because it uses a lightweight and efficient publish/subscribe methodology to ensure secure messaging between devices and centralized brokers, making information easily available. With this in mind, all MicroSmart FC6A Plus PLCs now support MQTT protocol, enabling effective IIoT connectivity and control between systems in the field and the cloud. This pivotal enhancement allows users to connect all types of field data to on-site and cloud-based brokers and makes the information readily available for users and analytical applications.

Metrol high temperature and high vacuum resistance precision limit switches have a 1-year warranty.
New additions to our offering of Sapiselco cable ties include CLICK Tie beaded cable ties, which allow release for reuse and have a double head that allows tying of a second bundle. New low-temperature UV resistant cable ties can be used outdoors in harsh cold weather conditions. Also new are assortment kits that include bulk amounts of nylon cable ties in various sizes and colors, in bulk amounts of 800 or 1,200 cable ties. The NITRA® pneumatic product line now includes the D2-Series double-acting, NFPA heavy-duty tie rod air cylinders ideal for use where abusive conditions exist. These pneumatic air cylinders have a 250 psi operating pressure and are interchangeable with other popular brands. New models are available with and without adjustable cushions to provide end-of-stroke deceleration at both ends. All D2-Series cylinders are constructed with high-quality aluminum components and a magnetic piston fitted with a PTFE wear band; all cylinders have a magnetic piston and can be used along with solid-state or reed switches for rod position sensing. The series includes bore sizes from 1-1/2 inch to four inches and stroke lengths from one inch to 32 inches to meet a broad range of applications. Models feature flange, rear clevis and rear pivot, side, base and rod clevis mounting options. These cylinders are proudly made in the USA and have a 2-year warranty. Rack and Pinions are mechanical gear components that convert rotary motion into linear motion. High precision Helical Gear Teeth, on both the Rack and Pinion, provide smooth and quiet linear motion. These pinions are designed to be mounted to the output shaft of our SureGear stepper or servo gearboxes, and also work with other popular brands. They are hardened and work with ISO 10 hardened racks. MTW machine tool wire is now also available in 1,000-foot reels for gauges ranging from 14 AWG to 22 AWG in various color choices. Existing MTW wire is sold in 500-foot spools for gauge sizes ranging from 20 AWG to 10 AWG in various colors, and in 2,500-foot reels for gauges ranging from 12 AWG to 18 AWG in various colors. Conductors are bare, annealed copper and the wire outer jacket is color-coded, Polyvinyl Chloride (PVC) that is flame-retardant and heat and moisture-resistant. Up to ten solid and four spiral-striped wire colors are available depending on wire size and length. MTW wire is UL approved, RoHS and CSA compliant and has a one-year warranty. MTW wire starts at $18.00 for 500-foot reels of 22 AWG wire. One of the easiest and most cost-effective ways to get data from remote equipment is to use a Moxa IIoT gateway with Ignition Edge Onboard™. You get a rugged field-tested platform that easily connects over Verizon™ or AT&T™ networks to Allen Bradley™, Siemens™, Modbus RTU/TCP, OPC UA, Omron™, DNP3, UDP/TCP, or serial devices. And you can enjoy significant savings by purchasing units with Ignition™ already pre-installed and licensed. Ignition Edge is designed and optimized for edge-of-network devices. It’s a version of Ignition that comes with unlimited tags and a variety of data-transfer protocol options. Ignition Edge enables data buffering, publish and subscribe to data through MQTT, remote alarming, and more. Benefits of buying Moxa device with Ignition Edge Onboard:
Fast operation and response times Support up to four analog and digital I/O expansion modules Built-in Video/Audio interface (8.4” - 15” screens only) Best-in-class LED backlight life of 100,000 hours Wide range of Operating Temperature
Advantech Solutions Architect Ted Phillips explains how MQTT, the defacto protocol of the IoT, works and why it has become the key building block of IoT applications.These monitors are available in a range of sizes (from 6.5” to 21.5”) and feature PCAP or resistive touch control to support diverse applications.

The CWB series of IEC contactors meets the requirements of a wide range of industrial applications. The magnetic contactors are available with AC or DC coils, in ratings up to 60hp at 575V. RW27/67 series thermal overload relays include (1) N.O. and (1) N.C. isolated auxiliary contact, and mount directly to the compatible contactor for compact and reliable installation. RW-E series electronic overload relays protect motors in a wide range of applications by offering selectable trip classes. WEG CWB series contactor prices start at $25.75, with a full line of accessories available. ESW/PESW series enclosed manual motor starters offer convenient pre-wired, ready-to-install units for operating the electric service to a motor. ESW series units with NEMA 1 rated enclosures offer a general industrial solution; PESW series units with NEMA 4 rated enclosures are perfect for harsh environments. Enclosed manual motor starters are priced from $88.00. MPW series manual motor protectors cover the function of motor starter, disconnect, controller, overload protection and branch circuit protection in a very compact device.

Quabbin multiconductor cable with twisted triads has been added to AutomationDirect’s current offering of instrumentation cable. These 300V UL cables with 18 or 20 AWG wire sizes are offered as 1, 2, 4 or 8 overall shielded triads, or individually shielded 2, 4, or 8-twisted triads with an overall shield. The overall shielded cables have an aluminum/polyester foil shield with 100% coverage and a tinned copper continuous drain wire for protection against external electrical noise interference. Cables with both individually shielded pairs and an overall shield have aluminum/polyester foil shields with separate tinned copper continuous drain wires. Individual conductor triads are stranded bare copper with black, white and red PVC insulation; the black PVC outer jacket is sunlight and moisture resistant. The UL ITC/PLTC listed triad cables are available cut-to-length in 1-foot increments starting at $0.25 / ft. (20-ft. min).
