why use a laser scanner instead of something else

The main benefits of the laser scanner is its versatility and non-intrusive presence. Unlike hard guards such as fences or safety floor mats, the laser scanner works without physical barriers. Due to its sensing technology, it is perfect for equipment that requires regular maintenance and cleaning. Fewer hard-guards are needed, allowing sweepers, forklifts, and loaders to transit through its protection area.

What is a safety laser scanner? A safety laser scanner is one of the newest technologies to be used for machine area safeguarding. This small optical sensor uses pulsed laser light to scan its surroundings. The scanner then compares the scanned information to its predefined zones. If the scanner detects an intrusion into that area, it sends a stop signal to the machinery being guarded.

How do they work? Safety laser scanners function by using a ‘time of flight’ measurement to determine distance. The scanner emits a light pulse, the light then hits the first object in its path and is reflected back to the scanner. Then the scanner compares the distance against the known size of its safety zone. If the scanner senses an intrusion into the safety zone, it sends a stop signal to the guarded machinery. This sequence is repeated as the optical assembly rotates, scanning the guarded area over and over. It uses harmless laser light to sense a guarded area

What do they do? Through user defined settings, they monitor a predetermined area for intrusions, making them a very effective safeguarding device.

What are they used for? Safety laser scanners are used for safeguarding dangerous areas and access points. Because they are so versatile, they can be used as a safeguard on both stationary and moving equipment. Applications for stationary use include, guarding a robotic work cell, guarding in front of a press or other hazardous machinery. It can be configured for multiple irregularly shaped hazardous areas, making it an excellent choice for safeguarding work cells, transfer lines, robot stations.

universal safety mat system


How the System Works:
The operation of a Universal Mat system is easy to understand. The mat is a simple, normally open switch. When a specified minimum weight is applied to the mat the “switch” closes. This sends a signal to the controller which, in turn, sends a stop signal to the guarded machine. Each mat presents four wires to the controller. This provides the redundancy required to monitor the wiring for open circuits due to incorrect wiring or physical damage to the wires. In order to meet many national safety regulations, STI offers trim to secure the mat to the floor so that it cannot be easily relocated and therefore become ineffective.

Presence sensing safety mats are used to monitor an entire hazardous area. They offer flexibility, quick access and may frequently be the most economic choice. Other options for perimeter guarding include interlocked barrier guards and safety light curtains. However, personnel can become trapped inside a barrier guard and safety light curtains only monitor the perimeter, not the hazardous area inside. Additionally, mats can also simplify routine tasks such as machine setup, maintenance and repair. Applications can be found throughout industry and typically include the following areas:

  • Material Handling
  • Assembly Machinery
  • Packaging Machinery
  • Robotic Work Cells

An STI Universal Mat system (UM series mat combined with an MC3, MC4 or MC6) offers a simple method for guarding personnel around hazardous machines. A Universal Mat system offers freedom, flexibility, and reduced operator fatigue when compared with traditional guarding methods such as interlocked fences, pullback restraints or perimeter barriers. Full visibility of and access to the work area is maintained. There is no need to worry about personnel forgetting to replace mechanical barriers or close gates.

    • Molded inside and outside corners available as an option
  • Mat Type: Normally open SPST, four-wire
  • Mode: Pressure Sensitive
  • Mat Size: Standard sizes from 12 x 12 in. to 48 x 72 in.
  • Activation Force: Detects adults. (66 lbs.)
  • Operating Temperature: -35 to 150°F
  • Conforming to Standards: ANSI/RIA 15.06-1999, ANSI B11.19-2003, OSHA 1910.217(b), CSA Z432-04
  • Approvals: When UM series mats are combined with an MC3, MC4 or MC6 controller the UM series safety mats comprise a system which has been EC type examined to the requirements of category 3, EN 954-1 and EN1760- 1:1998.
