Decrease reflection from the background object, e.g., by providing a sufficient distance to the background or by using a black sponge or similar material as the background. • Connection is made using a connector. Do not solder to the pins (leads). Use EE-1002 a connector or a EE-1003 (with a 1-m cable) connector.

Installation • When three or four Through-beam Sensors must be installed side-by-side, place the emitters and receivers on alternating sides. • When using a Reflective Sensor to detect slow moving objects, incorrect operation may occur even if two Sensors are installed side-by-side. • Be sure to keep the Amplifier Unit under 55°C even when using the fiber ends in high temperature environments. • The connection force of the fiber and the Photomicrosensor will decrease when the ambient temperature is high. If high ambient temperatures can be expected, install the fiber with a holder or clip, and do not pull on the fiber.
