Applied Robotics QS-25ANP-S1209 Robot Collision Sensor

Applied Robotics' QuickSTOP QS-25ANP-S1209 is a non-pneumatic collision sensor designed to protect industrial robots by providing immediate mechanical compliance plus a rapid E-stop signal. When a collision or excessive tool-load occurs at the end effector, the device yields to absorb the impact and simultaneously delivers a 24V stop command to the robot controller, enabling emergency shutdown in milliseconds. As part of the QuickSTOP family, it targets safety-critical automation tasks such as arc welding and material handling, where reliable collision protection complements other safeguards. The QS-25ANP-S1209 uses a dedicated 3-pin connector cable (S1209) for interfacing with the robot controller, aligning with documented cabling configurations for this model. Model-specific trip points, angular and torque limits, and mounting considerations vary by variant, so the official QS-25ANP datasheet should be consulted to determine exact installation requirements and electrical characteristics for your application.
