two series of safety light
curtains (active optoelectronic protective devices) are
designed for human protection and product/machine safety where risks cannot be
eliminated by machine design and the process might require frequent and open
access during operation.
The YBB-14 series has a 14 mm sensing resolution for
finger-size protection and an operating distance of up to 3.5 m; protective
heights range from 142 to 1,045 mm. The YBB-30 light curtains series has a 30
mm sensing resolution for hand protection and an operating distance of up to 12
m; protective heights range from 279 to 1,827 mm.
All safety light curtains
have Type 4 and Cat 4 PL e safety ratings and are IP65 rated. Light curtain
sender prices start at $250.00 and receiver prices start at $275.00. Mounting
brackets are included with each unit and additional mounting accessories and
protective columns are available.
AutomationDirect has also added a line of machine
switches to detect unsafe conditions and isolate power.
Normally-closed contacts are used for a positive break and redundant
normally-closed contact and normally-open feedback outputs are available. The
safety switches cannot be easily defeated and all units have CE, UL and CSA
approvals. Four bases are available: 30 mm plastic, 50 mm zinc alloy, 40
aluminum and 60 mm aluminum. Four types of interlocks are available for common
safety applications including tongue (key), shaft hinge, lever hinge interlocks
and pull cord actuators with reset for emergency stop or without reset for
simple stop. Safety interlock switches start at $15.00 and safety limit
switches start at $12.75.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
