<p>Data Sheet - Floor Pressure Mats / Sensors </p><p>Overview</p><p>Floor pressure mat sensors are designed to detect a person walking over them. Pressure mat sensors were initially intended for use in the security industry and comply to BS 4737 Part 3 : Section 3.9, however many other applications have been found for these floor pressure mat sensors such as; Sensors for interactive games and toys, sensors for interactive multimedia systems providing accurately targeted presentations. Pressure mat sensors offer a low cost covert method of detecting a person and will provide years of service. Pressure mat sensors should be mounted on a flat even surface and then be covered with a conventional floor covering such as carpet or matting. These pressure mats should not be used in safety critical applications. The pressure mat sensor is only 3 mm thick; the switch element is sealed into a welded PVC envelope and is available in a range of sizes and shapes. Custom sizes or shapes can be made to order.</p><p>Pressure Mat Operating Pressure</p><p>The operating pressure specification for our standard sensitivity range is; An alarm condition shall be generated by any force of not less than 100 N applied normal to the surface of the pressure mat by means of solid circular test disc of diameter 60 +- 5 mm, and shall not be generated by force less than 20 N applied by the same means. In reality this means a person walking over the pressure mat sensor when it is concealed under conventional carpet or rubberized matting will be detected. The more sensitive versions will detect hand pressure.</p><p>Electrical Specification</p><p>The switch configuration for two wires sensors is normally open, closing when a person treads on the mat. The four wire versions also have a security loop to provide 24 hour monitoring, this is required for the security industry.</p><p>Maximum Ratings Contact configuration for 4 wire pressure mat Operating voltage 25V dc/ac sensors Wattage 10VA Switching current 0.25 Amps Contact resistance 1 Ohm - dependant on operating pressure Operating temperature -5 to 45º C</p><p>Products</p><p>Product code High Quality Welded Floor Pressure Mat Sensors Size mm Box Qty PM1 Stair Tread Pressure Mat, 4 wire 595  170 mm 100 PM2 = 486 Standard Floor Pressure Mat, 4 wire 720  390 mm 50 PM3 Large Floor Pressure Mat, 4 wire 720  560 mm 50 PM4 Floor Pressure Mat, 4 wire – Pentagonal 570 * 430 mm 50 PM5 Floor Pressure Mat, 2 wire 330 * 260 mm 100 PM6 Floor Pressure Mat, 2 wire 400 * 235 mm 50 PM7 Stair Tread Pressure Mat, 2 wire - Increased Sensitivity 595 * 170 mm 100 PM8 Floor Pressure Mat, 2 wire – Increased Sensitivity 330 * 260 mm 100 PM9 Floor Pressure Mat, 4 wire – Oval 710 * 560 mm 50 PM10 Circular Floor Pressure Mat, 2 wire – Disc 305 mm 50</p>
