Fork Sensor

TAMPA, FL - TRI-TRONICS, a leader in manufacturing photoelectric sensors and rotary encoders, is proud to announce its second new product of 2018 - the FS Fork Sensor.

The FS Fork Sensor is the answer for those looking a cost-effective way to simplify thru-beam applications. Most fiber optic thru-beam applications can be expensive and tedious to install or calibrate the two separate devices required for the application. With the FS Fork Sensor, the light source and the receiver are housed in the same sensor, making installation easy.

"Over the years, TRI-TRONICS has gained a reputation for making rugged and reliable photoelectric sensors." TRI-TRONICS President Scott Seehawer said. "The FS Fork Sensor continues this reputation while being a cost-effective option for those not wanting to sacrifice performance."

The FS Fork Sensor comes in 8 different models with gap depths ranging from ranging from 0.787" (20mm) to 8.661" (220mm). Each sensor is accurate enough to detect objects as small as 0.5mm. Every FS Fork Sensor is 10mm wide and housed anodized aluminum, rated IP67. This makes the FS Fork Sensor small enough to fit into most tight spaces while offering the accuracy of bigger thru-beam sensors.
