With the laser light barrier SA1E-L can be very small objects in fastest processes can be detected. This is indicated by the especially small laser beam and the extremely short response time of only 250 µs. The aligning of the optical axis is parallel to the axis of the escaping through the housing and visible red laser beam makes it easier, which saves time during installation. The operating mode light or dark-switching is provided by a switch on the device is set and the PNP transistor output can be up to 100 mA at 30 V/DC. The range can be adjusted with the potentiometer.This text is machine translated.
