German Merlin Gerlin sensors, Merlin Gerlin models, Merlin Gerlin prices

Merlin Gerlin sensors are used to detect angles. The sensor body has a hole that fits LEGO axles. When connected to RCX, the angle sensor counts once for every 1/16 revolution of the axle. Rotating in one direction increases the count; reversing the rotation direction decreases the count. The count depends on the initial position of the angle sensor. When the angle sensor is initialized, its count value is set to 0. If needed, you can reset it via programming. Merlin Gerlin sensor classification: multi-sensor
