Product Snapshots – Issue 22, 2012

We have added several exciting products since our last edition of the Automation Notebook. Here are some highlights about some of those new products including: Digital pressure switch/transmitters, Safety glasses, More relays, Modular stacklights, Industrial managed Ethernet switches, ProSense™ pressure gauges and thermometers,Stellar™ basic soft starters.



Digital Pressure Switch/Transmitters

ProSense digital pressure switch/ transmitters are designed for air, no-corrosive gas and non-flammable gas applications. Fitted with a two-meter cable, the precision digital devices feature a three-color LCD display and provide two digital outputs and one analog output. Equipped with a lockable keypad, three operation modes and six pressure unit conversions, these switch/transmitters have two vacuum to pressure ranges (-14.5 to 14.5 and -14.5 psi to 14.5 psi), selectable response times to eliminate chattering, and a fast zero reset. ProSense digital pressure switch/ transmitters are cULus, CE, RoHS, and Reach approved.




Safety Glasses

Crossfire safety glasses, designed for use in the industrial workplace, combine required eye protection and comfortable fit in a lightweight non-industrial look. Providing excellence in technology and construction, every style meets American National Standards Institute (ANSI) requirements, and is marked with the ANSI Z87 2010 markings to meet the requirements of the industrial workplace. Frame styles available include frameless, half-frame, three-quarter frame, and full frame. Available lenses include smoke, clear, anti-fog, mirror, polarized, amber, and foam-lined. Polycarbonate lenses provide superior optical quality and impact protection while blocking 99.9% of harmful UVA and UVB rays.



More Relays

New electro-mechanical and solid state relays including hockey puck style panel mount relays with high load ratings up to 75 amps have been added to our extensive relays and timers lineup. New ice cube style and octal base hermetically sealed (HazLoc) relays are designed for applications requiring sealed relays for hazardous factory locations. (Class I, Div. 2 Groups A, B, C, D). AD-PR40 series power relays are open construction design with high power contacts capable of switching up to 40A. SPDT, DPST and DPDT models are available. Class 8 solid state relays for up to 10 Amp loads and the similar Class 8 hazardous location series offer energy efficient current switching in a slim housing ideal for space-saving DIN rail or panel mount applications.


stack-lightsModular Stacklights

WERMA stacklight systems, with modular bayonet-style assembly, allow elements to be mechanically and electrically connected easily and safely within seconds. The 70mm IP65-rated KS 71 series provides up to five elements per terminal base. Light elements include incandescent, LED and Xenon tube models; select elements are available in various light effects (permanent, blinking, rotating, flashing). Audible elements include buzzers and multi-functional sirens. The 50mm KS 50 modular IP54-rated system accommodates up to four elements with either permanent or blinking light effects. A choice of incandescent or LED light sources is available as well as an 80 dB audible element. A wide variety of wall, base, tube, magnetic and fold away mounting options are available.



Industrial Managed Ethernet Switches

Stride™ industrial-grade managed Ethernet switches feature redundant power inputs with surge and spike protection and auto-crossover. Built with aluminum housings, all models are designed for an operating temperature range of -40 to +75 °C. The Stride managed Ethernet switches’ proprietary Real-Time Ring™ technology provides the fastest recovery of all the redundancy options on the switch. Most models feature multiple 10/100BaseT RJ45 Ethernet ports; additional models include ST or SC type fiber optic connections. Gigabit managed switches are also available, with10/100/1000BaseT RJ45 ports and advanced combination SFP ports that accept noise-immune fiber optic links. DIN-rail mountable, managed Ethernet switch prices start at $445 and are backed by a two-year warranty. Small form-factor pluggable (SFP) industrial Ethernet fiber transceivers have also been added. The compact, hot-swappable transceivers feature LC fiber connectors to add fiber connectivity at Fast Ethernet or Gigabit Ethernet speed.



ProSense™ Pressure Gauges and Thermometers

ProSense mechanical dial pressure gauges are available in a variety of configurations for use in most pneumatic, hydraulic, HVAC, plumbing, industrial and commercial applications. These high quality gauges use Bourdon tube sensing elements and do not require any external power sources to operate. Center back mount and lower mount cases are available in durable steel or stainless steel and in either dry or liquid filled to dampen vibration and pulsations. Brass wetted parts are suitable for air, oil, or water applications while stainless steel wetted parts are available for corrosive applications. Dual marked dial faces (psi/kPa or inHg/kPa) are available in pressure ranges from vacuum up to 6000 psi. The ProSense bi-metal thermometers are general purpose thermometers ideal for applications such as, industrial process, hot/chilled water lines, boilers, HVAC, food processing and wastewater. Constructed of 304 stainless steel, thermometers are available in three-inch dials with center back mounts and five-inch dials with adjustable angle mounts. Both styles feature a bi-metallic sensing element, a dual scale (F°/C°) and re-zero adjustment screws. Models are available with welded stem lengths ranging from 2.5″ up to nine inches.



Stellar™ Basic Soft Starters

Stellar SR33 Series basic soft starters are designed for general purpose applications where traditional across-the-line starting or wye-delta starting would typically be appropriate. The SR33 semi-conductor soft starters, available in 22A to 482A sizes, are suitable to control three-phase AC induction motors with a wide variety of motor loads. This series is an ideal substitute for a Star/Delta starter as it fits into a similar footprint, simplifying installation. All units feature two-phase control, easily and separately adjustable motor start voltage and start and stop times, and depending on model, fault indication of 4 or 7 fault types: SCR or Power Supply, Overheat, Control Power Supply, Bypass Relay Failure, Shearpin, Overload, and Overcurrent. Ideal for applications such as pumps, blowers and conveyors, the SR33 series soft starters use thyristors for controlled reduced voltage motor starting and stopping, and then switch to internal contacts for efficient running at rated speed.
