カタログの抜粋

■ Robust design for rough applications with high resolution requirement such as crane technology, construction machines and special engineering ■ High vibration and shock resistance thanks to the compact mechanical design ■ Resolution < 22 bit / 360° ■ Speed signal in digits/ms with variable gate time ■ Protection type IP 66 Design - Robust housing (wall thickness 5 mm) manufactured from seawater-proof aluminium (AlMgSi1) or stainless steel (material: 1.4305 optionally 1.4404). - Position recording and evaluation are of a redundant design to implement a reliable position value and speed signal. - A network in/out module with transient filtering, voltage supply and output driver unit forms the electrical interface. - Electrical connection via two M12 connectors, 5-pin, pin and socket for bus IN / bus OUT. Function A correct mechanical connection between the customer and sensor shaft ensures that the sensor precisely detects the customer shaft's rotations. A safe position is provided by the plausibility check of two sensor systems. Detected errors are evaluated. The CAN interface outputs the validated position value and speed signal via the CANopen Safety protocol within an SRDO (Safety Relevant Data Object) using 2x2 messages (normal and inverted). The rotary encoder meets the conditions of safety level SIL2 according to IEC 61508 and performance level "d" according to EN13849. The prerequisite of safety-relevant operation is a failsafe master.
