The S18U Series of compact ultrasonic sensors features an advanced microprocessor design, pushbutton programming and bright diagnostic status LEDs located directly on the sensor housing.
Luminescence sensors aren't fooled by colour
The QL50 and QL55 self-contained luminescence sensors use a modulated ultraviolet LED to scan for luminescence in materials, and are not affected by colour or contrast shifts.
Fixed blanking allows for stationary objects such as tooling or materials inflow to be ignored when positioned in a defined set of beams.
If the objects are removed, the system goes into a lockout mode to ensure an unsafe gap in the sensing field is not created.
"Fixed blanking is a powerful new feature which adds to the overall flexibility of the system to incorporate the complexities of the manufacturing process while maintaining proper safeguarding of the operator," said Mike Carlson, technical manager for Banner's safety products.
Fixed blanking is programmed via onboard DIP switches, making materials or tooling changeovers fast and easy.
Also significant is a flexible cascading option that allows up to four systems of varying sizes, lengths and resolutions to be wired together to form a unified control stop element with a single cable interface.
Cascaded system response time is only minimally affected with the addition of each system in the cascade adding a maximum of 2 ms to the overall response time for each additional pair in the cascade.
A response time can also be calculated for each individual system pair.
"E-stop buttons, safety switches and safety module output contacts can also be interfaced at the end receiver to provide even greater flexibility in the machine safeguarding solution," Carslon added.
Optional AC power supplies with safety relay outputs add yet another dimension of flexibility to the EZ-SCREEN system.
"Offering AC power interface solutions for the EZ-SCREEN system ensures that Banner safety light screens can truly solve the widest range of applications," Carlson also stated.
