Square wave output for models

with PPR 1, 10, 12, 20, 60 and

100. Square wave, 50/50 duty

cycle ±10%.

Models that use 1/3 yd. or 1/3 mtr

wheels with internal ÷ 3 circuits.

66/33 duty cycle.

Models with 120 and 200 PPR

utilize internal doubling. (50 μsec

±20% neg. going pulse.)

* Rotary pulse generators and length sensors with 120 & 200 PPR outputs employ

an internal doubling circuit and deliver a fixed 50 μsec ±20% output pulse at the

leading and trailing edge of a passing slot. Additional doubling in external

indicators or circuits may not be applicable. These outputs are derated to 7300

Hz due to internal x2 circuitry. (See Wave Output Diagram)

Notes:

1. For 25 foot cable, replace the last character of the part number (“C”) with “D”.

For 50 foot cable, replace the last character of the part number (“C”) with “E”.

2. Wheels and mounting brackets are sold separately, see Length Sensor Accessories.
