Telco sensors for refrigeration and storage

August 2021 Sensors & Transducers

Mobile racking enables compact storage while keeping the stored pallets individually accessible. Where storage space is expensive, for example in cold stores, mobile racking is the perfect solution. Telco Sensors makes sure safety is guaranteed by an infrared beam system, mounted on each mobile rack and at the outer sides of the complete installation.

The light transmitter (LT) and light receiver (LR) are installed so the beam runs parallel along the bottom edge of the storage rack, approximately 10 cm in front of it. If there is any object or person present, the beam will be blocked and the Telco amplifier (PA) will activate the output and the rack controller will deactivate the motors immediately. The rack will continue its movement as soon as the beam has been re-established.

The Telco 9000 series Spacemaster transmitter and receiver offer a solid state relay output as an alternative to the NPN/PNP transistor type. They also eliminate cross talk between four operating frequencies (channels), for 0-70 m self contained sensing.
