Fork sensors offer high excess gain
December 2003
Sensors & Transducers
Telco Fork Sensors are based on the through beam sensing principle. Through beam mode is the most efficient use of infrared light, enabling the highest level of excess gain when required.
Telco Fork Sensors have the advantage that both the transmitter and receiver are built into the same sturdy anodised aluminium housing, enabling both problem free adjustment and mounting. The solid structure ensures that they are all shock, vibration proof and IP67 sealed. The housings are available in various sizes with full gain and NO/NC adjustment through an internal potentiometer. A supply voltage of 10 -35 V d.c. PNP/NPN output, high switching frequency of 4 kHz and a resolution of down to 0,4 mm, with a light immunity of up to 70 000 lux, all of which means that these sensors live up to today's sensing requirements.
