Flipx professional with green light

Product Details

Part of the FlipX Standard Series, the FLX-S-DT is Optex's latest indoor Dual-tech PIR sensor with new to the market, innovative pyro sensor with human catch element for creating human-sized detection areas and superior pet tolerance. Equipped with a rotatable lens FlipX sensors allow an easy switch from wide to narrow detection, meaning that you can do twice as much with a single product. It's the perfect choice for everyday intrusion detection in residential or small commercial sites and can cover various installation fields. The FLX-S-DT model features dual technology (PIR and microwave detection) for improved performance in challenging indoor environments.

Dual technology

The FLX-S-DT is a dual technology sensor using both PIR and microwave detection. Only when both the PIR and microwave activate will the alarm be triggered. However what really makes the FlipX stand out is the use of our bespoke Tough MOD 2 which unlike other microwave sensors, tailors its detection range to the IR sensor, providing higher levels of capture perfomance whilst mitigating false alarms.

Advanced pyro sensor

Equipped with the latest technology, bespoke pyroelectric sensor, the FlipX Standard ensures high performance and accuracy. What makes the sensor unique is its ability to adapt to the human shape and differentiate humans with greater clarity, avoiding false alarms triggered by pets.

Rotatable lens

The FlipX Standard features our innovative, time and money saving solution - the rotatable lens. The sensor comes with the factory setting of wide detection but by simply removing the cover and fliping the lens 180degrees you can create a whole new narrow detection area for corridors, window protection and more. Note microwave sensor is disabled when the device is used for narrow applications.

Spherical lens design

The specially designed spherical lens provides a precise focal length of each detection ray onto the pyroelectric elements. This advanced lens design helps to ensure consistency throughout the field of detection and considerably reduces the chance of missed alarms

SMDA logic

All FlipX series are equiped with a digitally enhanced signal recognition logic, "SMDA". This highly developed detection technology helps the sensor avoid nuisance alarms from shades, changes in temperature or brightness which can be common in indoor settings. With this enhanced digital logic you can get piece of mind that your alarm will not be activated by everyday triggers. In this model we have also incorporated features from outdoor sensors, to make it more resistant and durable for everyday indoor detection use.

Easy installation

The FlipX Standard comes with an easily viewable LED indicator in green so you are sure the sensor is turned on and working. It also comes with a 180 degree cover lock which can be easily removed to rotate the lens and change the detection area from wide to narrow.

Key Features

  • hardwired indoor dual-technology (PIR + microwave) with rotatable lens
  • wide detection up to 12m, 85 degree, and narrow detection up to 18m (PIR only)
  • Superior pet tolerance with new pyroelectric element
  • Tough MOD 2 for higher capture rate


The FlipX Series will replace the majority of our older indoor PIRs as shown below (some have already been discontinued):

FLX-S-ST is replacement model for EX-35, RX-40QZ FX-40, FX-40D, RXC-ST

FLX-S-DT is replacement models for MX-40QZ, MX-40PT, RXC-DT

FLX-A-AM is replacement models CDX-AM, CDX-NAM

FLX-A-DAM is replacement models CDX-DAM

The FlipX Series provide superior pet tolerance through the sensitivity settings. If you put the sensitivity mode to low, this will invoke pet immunity. In this mode, thanks to the innovative pyroelectric sensor and human catch element, small animals will not activate the sensor.
