Position sensors feature 10m range

Variohm EuroSensor has expanded its position sensor range to include models that are available ex-stock from Celesco Inc. Aimed at demanding applications in outdoor mobile equipment such as cranes, hoists and hydraulic lifts, the SK series also suits long range position monitoring for industrial machinery.

The modular range offers stroke options of 6.4 and 10.2m with a variety of electrical interfaces, including CANbus, voltage and current output, in addition to a choice of plastic-hybrid potentiometer sensing or flange-mounted encoder.

With its glass-filled polycarbonate housing the SK series features IP67 environmental rating and dimensions of 165 x 109 x 139mm. With maximum cable velocity of 1.5m/s and acceleration to 5g, the sensor has a life rating in excess of 250,000 cycles and operating temperature range from -40 to +85°C.

Four of the models in the SK series feature Celesco’s plastic-hybrid precision potentiometer that is said to offer accuracy of 0.35% FS and repeatability of 0.05% FS. These models comprise the SKD with a user selectable 4 to 20mA or 0 to 10Vdc output; the SK1 with a voltage divider output; the SKH-CAN with a CANopen interface, and the SKJ-CAN with CANbus SAE J1939. A fifth model, the SK6-Encoder offers the possibility to incorporate any standard 2½in square flange or 58mm synchro-flange encoder.
