Passive Sensor Passive Type Far Infrared Type PA-5312PA

Passive Sensor Passive Type Far Infrared Type PA-5312PA

A three-dimensional detection sensor ideal for detecting remaining occupants and ensuring safety in multi-story parking lots.

■Catching far-infrared energy emitted by humans The passive sensor (PA-5312PA) detects the difference between far-infrared energy emitted from objects such as walls and floors and that emitted from the human body with high sensitivity, outputting a signal. It is an ideal three-dimensional detection sensor for detecting residual individuals and ensuring safety in tower parking systems and similar applications. ■New fuzzy processing adopted For the first time in the world, fuzzy theory has been applied to passive sensors. The two outputs from the newly developed dual twin elements are processed by the CPU to separate the temperature difference and shape difference between the detected object and the background, allowing for accurate determination of whether the detected object is a human using fuzzy theory. It is hardly affected by phenomena that are likely to cause false triggers, such as small animals (like mice and cats), stray light, drafts, and external noise. ■High-density detection area Utilizing unique optical technology, a multi-parabola mirror has been adopted. This achieves an ideal detection area and allows for high-density detection in three-dimensional space. Additionally, it is compatible for installation on ceilings and walls.

Passive Sensor 3D Surveillance Type PA-6812B

Passive Sensor 3D Surveillance Type PA-6812B

Basic sensors with energy-saving and compact design!! The black (BL) version is now available for all models.

■Energy-saving Design 1 (Low Current Consumption) Reduces current consumption to about one-third (8mA) compared to our conventional products. Allows the use of smaller power supplies, leading to cost reduction. ■Energy-saving Design 2 (Low Voltage) Operating voltage is DC 7 to 30V. Enables the selection of wiring materials and long-distance wiring without much concern for voltage drop due to wiring resistance. Suitable for renewals as well. ■Black Color Available for All Warning Models We have introduced a black version that considers harmony with ceilings in temples, shrines, museums, art galleries, and stores. This allows the sensor to blend into the background and remain inconspicuous (without compromising aesthetics). The visibility and sensitivity of the LED are equivalent to the white version. ■Unique Warning Area Configuration Our unique optical technology creates a sharp warning area, providing effective detection performance regardless of area settings with a movable mirror. ■Improved Installation and Maintenance We have adopted a snap-in method for attaching and detaching the sensor unit and base unit, allowing for one-touch operation and smooth work.

Passive Sensor PA-470A

Passive Sensor PA-470A

Passive sensor for wall and corner installation with abundant features.

■ Adoption of Fuzzy Theory The two outputs from the newly developed dual twin element are divided into two pieces of information: the temperature difference and shape difference between the detection object and the background, which the CPU uses to accurately determine whether the detection object is a human or a small animal using fuzzy theory, and outputs an alarm. Even when phenomena that are likely to cause malfunctions, such as small animals (like mice), stray light, drafts, and external noise occur, the dual twin effect ensures that there is almost no influence. ■ Combined 3D and Area Surveillance By operating the mode selector inside the sensor and changing the lens, it can also be used for area surveillance. The surveillance area is effectively monitored up to 16m for 3D surveillance and 20m for area surveillance. ■ Abnormal Alarm Function While the sensor is in a surveillance state, it monitors the next functions through an internal program. If an abnormality is detected, it alerts with continuous alarm output and indicates the abnormality with an alarm display light. ■ Auto Reset Memory Function When multiple sensors are connected, it is possible to confirm which sensor triggered the alarm by the blinking or lighting of the display light.

Passive Sensor 3D Surveillance Type PA-6812WA

Passive Sensor 3D Surveillance Type PA-6812WA

Wide-base passive sensor with built-in anti-blind function.

■Anti-Blind Function This function detects interference applied to the front of the sensor. If an obstruction is attached to the front, it will issue a warning through the output of a trouble alarm and the illumination of a trouble indicator light. Once the obstruction or prank is removed, the output will stop, but if a trouble alarm has been triggered, please immediately check the operation of the sensor. ● As a warm-up, the trouble alarm will not be output for about 2 seconds after power is turned on. * Transparent sprays or items with low near-infrared reflectivity may not be detected. Wide Base Design ● By widening the base (Φ150mm), the issue of noticeable dirt marks on the ceiling surface during sensor replacement is resolved. ■Auto Reset Memory Function When multiple sensors are connected, you can confirm which sensor triggered the alarm by the blinking and illumination of the memory indicator light (yellow) during the alert. ● The memory indicator light will blink for 3 minutes after the alarm is triggered, then continue to illuminate for 47 minutes before automatically turning off. ● This function can be disabled using the mode selector.
