Signalquest SQ-SEN-645B Zero-Power Tilt Sensor, 45° Bi-directional Activation

Technical description of the product (SQ-SEN-645B):

The SQ-SEN-645B series is a zero-power tilt sensor that functions as a position-sensitive switch. It is normally open when vertical and normally closed below its switch angle. Designed for non-sensitivity to vibration in the vertical position, the sensor settles in an open state when at rest vertically. When tipped down from vertical to the switch angle, it generates continuous on/off contact closures during motion. When at rest below the switch angle, it settles normally closed. Functions: * Chatters open/closed when tilted or vibrated in any direction, regardless of orientation. * Non-sensitive to vibration or lateral movement when open. * Normally closed when below or between the switch angles. * Normally open when vertical. * Off-vertical activation. * On/off tilt sensing. * Tilt down detection. Features: * **Activation Angle:** Bi-directional 45° and -45°. * **Industrial Rated:** 10-year life, -40 to 85 °C. * **Zero-Power:** Normally < 50 nA when activated. * **Miniature Size:** 3.3 mm x 6.9 mm. * **Simple Interface:** No signal conditioning required. * **Surface Mount:** RoHS & REACH compliant, lead-free, halogen-free. * **Made in USA:** Fully automated production, 100% testing, worldwide quality and price leader. Applications: * Motion-triggered wake-up. * GPS tracking, RFID, vehicle electronics. * Security, anti-tamper, anti-theft, alarms.
