SQ-SEN-815B

Product catalog summary
Function: The SQ-SEN-8XX is an on/off tilt sensor that is normally open when horizontal and closes below a certain angle. It is designed to be non-sensitive to vibration when in a horizontal position.
Applications: This sensor is used in security systems, anti-tamper and anti-theft devices, alarms, TV remote controls for tilt wake-up, and screen orientation adjustments.
Description: The sensor acts as a position-sensitive switch, remaining open when horizontal and closing when tilted beyond a specific angle. It is designed to minimize power consumption and is sensitive to position changes rather than vibration.
Features: The sensor features zero-power consumption when activated, high sensitivity, long life due to semiconductor-grade electroplating, a miniature size of 3.3 mm x 6.9 mm, and a simple interface without the need for signal conditioning. It is RoHS compliant and available in various activation angles.
Theory of Operation: The sensor operates by opening or closing contacts based on its orientation. It is normally open in certain orientations and closes in others, with a high probability of remaining closed when at rest in a closed orientation.
Functional Behavior: The sensor's switch closes at specific angles down from horizontal and opens back at different angles. For example, the SQ-SEN-815 closes at 15 degrees and opens at 2 degrees.
Characteristics: The sensor can withstand shocks up to 5,000 g, operates within a temperature range of -40°C to 85°C, and supports a supply voltage range of 0.5 V to 12 V.
Dimensions: The physical dimensions for the 8XX and 8XXB series are provided, detailing length, diameter, and terminal widths.
Product Comparison: The datasheet compares different grades of the sensor based on assembly method, temperature range, and service life.
Ordering Guide: Provides part numbers and packaging codes for ordering different models of the sensor.
Limitations and Warnings: The sensor is not intended for life support or safety equipment where failure could result in injury or death. Users assume all risks associated with such applications.
Testing: Each sensor undergoes performance verification during production, and system integration testing is recommended to ensure compatibility and safety.
Notice: The document may contain errors, and specifications are subject to change. Users should verify information and perform thorough testing.

SQ-SEN-8XX ON/OFF TILT SENSOR, HORIZONTAL NORMALLY OPEN On / off tilt sensing Non-sensitive to vibration when open Normally open when horizontal Normally closed when below the switch angle Zero-power Normally - < 50 nA when activated High Sensitivity & Long Life - Semiconductor grade electroplating Miniature Size - 3.3 mm x 6.9 mm Simple Interface - No signal conditioning required Quiet - Undetectable sound level Surface Mount- RoHS compliant, lead-free, tape and reel Activation Angle - Available in 15°, 30°, 45°, 15° Bi-directional Made in USA - fully automated production, 100% testing, worldwide quality and price leader FUNCTIONAL DIAGRAM Security, anti-tamper, anti-theft, alarms TV remote control tilt wake-up Screen orientation DESCRIPTION The SQ-SEN-8xx sensor acts like a position sensitive switch that is normally open when horizontal, and normally closed below the switch angle. It is designed to be non-sensitive to vibration a horizontal orientation. When at rest in a horizontal orientation, the sensor will settle in an open state. When tipped down from vertical to the "switch angle" it will produce continuous on/off contact closures while in motion. When at rest below the switch angle, it will settle normally open.

SQ-SEN-8XX ON/OFF TILT SENSOR, HORIZONTAL NORMALLY OPEN THEORY OF OPERATION The SQ-SEN-8xx sensor acts like a position sensitive switch which is normally open in a range of orientations, and normally closed in another range of orientations. When resting in a normally open orientation, contacts are virtually guaranteed to be open. When resting in the normally closed orientation (unlike normally open) contacts are not guaranteed to be closed. A good rule of thumb is that they will be closed 95% - 99% of the time, when at rest. When in a normally closed orientation, the sensor will chatter open...
