ZSFM323511 Pyroelectric Sensor Specification PS040701-0222 Page 1 Overview Zilog’s Passive Infrared (PIR) sensors are designed to deliver high performance and excellent EMI immunity for the most demanding motion detection applications. The ZSFM323511 PIR sensor is a surface mount device compatible with IR reflow processes. It is used in combination with a PIR lens and consists of two sensing elements behind a spectral filter window tuned to 8-13um wavelength to help block out unwanted IR energy sources. The 0.6mm element spacing provides additional white light protection. The ZSFM323511 has a standard profile making it compatible with clip-on lenses used with standard TO5 package PIR sensors.

Features

The key features of ZSFM323511 are:

• Dual-element balanced differential (series opposed) PIR sensor
• High PSRR
• Built in EMI compensation
• White Light Protection
• Elements are 0.75mm x 2.3mm spaced 0.6mm apart
• Surface Mount package
• Recommended operating voltage range of 1V to 15V
• Operating temperature range of -40C to +70C

Applications

• General purpose motion detectors
• Lighting
• Video Doorbell
• IP Camera

ZSFM323511 Pyroelectric Sensor Specification PS040701-0222 Page 11 Usage Restrictions and Precautions This section presents restrictions and precautions that apply to Zilog pyroelectric sensors. Design Restrictions and Precautions This sensor is designed for indoor purposes in which secondary accidents due to operation failure or malfunctions can be anticipated; therefore, add appropriate fail-safe functionality to your design. If these sensors are intended for outdoor applications, be sure to apply suitable supplementary optical filters and use a waterproof enclosure. Usage Restrictions and Precautions To prevent sensor malfunctions, operational failure, or any deterioration of their characteristics, do not operate these PIR sensors under the following, or similar, conditions:

• Rapid environmental temperature changes
• Strong shocks or vibrations
• In places where there are obstructing materials (glass, fog, etc.) through which infrared rays cannot pass within the detection area
• In fluids, corrosive gases, and sea breezes
• Under continual high-humidity atmospheric conditions
• Exposed to direct sunlight or automobile headlights
• Exposed to directly to forced-air currents from a heater or air conditioner Handling and Storage Restrictions and Precautions To prevent sensor malfunctions, operational failure, appearance damage, or any deterioration of their characteristics, do not expose these sensors to the following, or similar, handling and storage conditions:
• Vibrations over extended periods
• Strong shocks
• Static electricity or strong electromagnetic waves
• High temperature and humidity over extended periods
• Corrosive gases or sea breezes
• Dirty and dusty environments that may contaminate the optical window
