The difference between HTL and TTL-Coslight cable displacement sensor, cable displacement sensor, cable encoder, cable encoder

Difference 1. Different transmission distances.

1. HTL: For HTL encoders with symmetrical negative signal output, the signal transmission distance can reach 311 meters.

2. TTL: For TTL encoders with symmetrical negative signal output, the signal transmission distance can reach 160 meters.

Difference two, different voltages.

1. HTL: The threshold voltage is relatively high. When the power supply voltage is 15V, the threshold voltage reaches 7-8V.

2. TTL: The most commonly used is because data representation usually uses binary rules, +5V equals logical \"1\", 0V equalslogical \"0\".

Difference three, different attributes.

1. HTL: high noise tolerance and strong anti-interference ability. The disadvantage is that the operating speed is relatively low, so it is used for some industrial control equipment that does not require high operating speed and can withstand dry winding.

2. TTL: TTL level signals connect directly to integrated circuits without the need for expensive line drivers and receiver circuitry; data in devices controlled by computer processors. The transmission speed is high, and the TTL interface can meet this requirement. In most cases, TTL communication uses parallel numbers.

TTL is along-line differential drive (balanced A, A-; B, B-; Z, Z-), HTL is also called push-pull, push-pull output, and the encoder signal receiving device interface must match the encoder.For For TTL encoders with symmetrical negative signal output, the signal transmission distance can reach 150 meters. For HTL encoders with symmetrical negative signal output, the signal transmission distance can reach 300 meters. HTL has a higher operating voltage than TTL Much, the high-level output voltage is much higher than that of TTL devices, and the low-level output voltage is also slightly higher than that of TTL devices. HTL is considered a European standard in terms of application. HTL will have a higher voltage than TTL, but now TTL also has a high voltage version
