Product Description

The RT80240LF102C Encoder produced by Danaher depends on incremental encoding for operation. This device converts rotary motion into electrical pulses to track the position, speed, and direction of a rotating object for industrial automation. Operators can choose resolutions between 100 and 2540 pulses per revolution when using this system. This encoder draws up to 80 mA of current.

The quadrature phasing rating of this RT80240LF102C encoder spans from 90 degrees to a plus or minus range of 36 degrees electrical. This electrical system function maintains symmetry at an exact 180-degree angle range, which is between ±18 degrees. The squarewave output produces both rise and fall transitions less than one microsecond duration under a 1000 pF load condition. The RT80240LF102C encoder ensures accuracy reaches ±2.5 arc-minimum between any two pulses and ±3 times 360 divided by PPR. The system uses a 7272-line driver, which is equivalent to power signal output functions. The output circuit properties enable both supply and current measuring functions at a maximum rate of 40 mA. The programming supports operation between 100 kHz minimum and above. The encoder keeps its signal quality consistent throughout its wide operating speed spectrum.

The RT80240LF102C encoder functions using various power supply inputs. It operates with a power input range of 5 VDC ± 5% and 12 or 15 VDC ± 10%. The encoder proves essential for establishing stability in motion control systems. The encoder produces signal transitions of high clarity regardless of operating environment conditions. From –25 to +70 degrees Celsius the device can be safely stored. Channel A leads B during clockwise rotation as viewed from the shaft end. The gated index pulse has a width ranging from 90 degrees to 115 degrees with a tolerance of 25 degrees.

Frequently Asked Questions about RT80240LF102C


Q: How does the sub-1µs signal transition time impact RT80240LF102C's signal integrity under capacitive load?

A: Fast rise/fall transitions reduce signal skewing in RT80240LF102C. This allows dependable high-frequency performance even under 1000 pF capacitive load.

Q: What role does the dual voltage input range play in the RT80240LF102C Encoder?

A: Dual voltage input in RT80240LF102C increases installation flexibility across different power infrastructures. It allows the encoder to adapt to varied system voltage levels.

Q: How does the current draw of 80 mA in RT80240LF102C affect power system compatibility?

A: RT80240LF102C's low 80 mA current ensures it integrates easily with most control systems. It maintains performance without overloading low-power circuits.

Q: How does the encoder handle rapid speed changes in automation environments using RT80240LF102C?

A: The robust design of RT80240LF102C allows accurate encoding during speed surges. This maintains signal integrity and timing without waveform distortion.

Q: What is the significance of the gated index pulse width in RT80240LF102C Encoder?

A: The gated index pulse helps in zero-position referencing during shaft rotation. In RT80240LF102C, this enables accurate homing and alignment operations.
