RIKEN OPTECH CORPORATION RPZ Direct Projection Type Safety Light Curtain
Manufacturer: RIKEN OPTECH CORPORATION
Model: RPZ
Features
- Failsafe design for the highest level safety
The highest level safety has been realized based on a failsafe design that utilizes mutual checking performed by two CPUs equipped in the receiver, and redundancy of the signal-processing circuit and output circuit.
Complies with international standard IEC61496-1/2 and North American standard UL61496-1/2.
Complies with China Standard GB4584-2007(some models) - Diverse line-up to cope with various operating environments
Select the optimal safety light curtain according to the installation environment, type of press and work content. - Series connection function and error display function equipped
Flexible installations matched to the operating environment and work content - Simple to adjust beams
LED indicators equipped: Determine status of main unit with a single glance - Mutual interference prevention
When multiple RPZ units are installed, a light interference avoidance algorithm (assigned according to the respective wavelengths of light sensors ) can prevent mutual interference (up to three sets).
Safety Device Selection Criteria (Protective Range)
- Mechanical press: (Die height + Stroke length) or more
- Hydraulic press: (Full daylight range) or more
* Note that the necessary protective range varies according to the installation conditions. - In the case that the top beam height at the time of installation is 1,400mm or less from the floor surface
→ (Die height + Stroke length + Insufficient length) or more - In the case that the top beam height at the time of installation is more than 1,700mm from the floor surface
→ (Die height + Stroke length – Excess length) or more
* Lowest beam position is assumed to be the top surface of the bolster.
