Shaft Encoder RL-P Series - Optic Shaft Encoder
RL-P Programmable Heavy Duty Shaft Encoder

The RL-P rotary shaft encoder directly couples to a rotating shaft and produces a specified number of square wave output pulses per revolution of the shaft. The number of pulses per revolution is determined by setting configuration switches accessible through an access port near the connector. Any one of a predefined set of pulses per revolution are available.

It comes with a 3/8", 1/2", 5/8", 8mm, 10mm, or 3/8-16 or 1/4-20 threaded shaft for heavy duty applications where a face mounted encoder is required. The rugged 3" diameter by 2-3/8" deep enclosure is constructed of 1/4" thick aluminum with a 5 or 6 pin connector on the side.

Metric bolt holes are available - see M96 and M105 modifications.

PROGRAMS

The RL-P is preconfigured at the factor with one of many predefined programs. Proam options are selected at installation time by setting configuration switches. Call or see website for details about available programs.

TYPICAL PROGRAM FEATURES

Selectable Pulses per Revolution: pulses per revolution on one, two, or three outputs can be selected from a predefined set.

Anti-jitter: Increases the pulse hysteresis to 1/2 of pulse width, eliminating the effects of mechanical vibration and the pussible dither that results in false output pulses. For example a 10 pulse per revolution output would have 18° hysteresis (i.e. 360° ÷ 10 x 1/2).

Direction Indicator: Indicates direction of shaft rotation.

Fractional Pulses per Revolution: for example 2.5 pulses per revolution.

Speed Indicator: Sets the ouput when a predefined rotational speed is attained.
