PS991416 ipf electronic Laser Sensor

Optical sensors operate without contact. These detect objects regardless of their nature (eg shape, color, surface structure, material). The basic operating mode is based on sending and receiving light. Three models are distinguished: 1. The barrier photocell is made up of two separate pieces of equipment, a transmitter and a receiver, which are aligned with each other. When the light beam between the two devices is interrupted, the switching output integrated in the receiver changes state. 2. In the reflective photocell, the emitter and the receiver are inside a team. The emitted light beam is reflected onto the receiver by a reflector that must be mounted opposite. As soon as the light beam is interrupted, the switching output integrated in the device changes state. 3. In the self-reflective photocell, the emitter and the receiver are inside a team. The emitted light beam is reflected by the object to be detected. As soon as the receiver detects the reflected light, the switching output integrated in the device changes state.
