Mysterious Studio Escape Room Props Metal Sensor Metal Objects Close to Metal Sensors in a Correct Sequence to Unlock Metal induction

WIDE APPLICATIONS: An inductive proximity sensor is a type of sensor that generates an electromagnetic field to detect metal targets within its sensing zone. The most commonly detected targets include iron, brass, copper, aluminum, and stainless steel. HIGH PRECISION DETECTION: Mysterious Studio metal proximity sensor can accurately detect metal targets within the sensing zone, providing high precision detection for your needs. GREATER SENSING RANGE: Unshielded sensors have a greater sensing range, requiring a specific free zone around the sensing face to avoid affecting the sensing characteristics. Mysterious Studio 16mm proximity sensor has a sensing distance of 3-4mm..syi
