RL-P Programmable Shaft Encoder | Photocraft by TRI-TRONICS

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", or 5/8" 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.

When coupled to a rotating shaft, either directly with a flexible coupling or using a timing belt, it converts shaft rotation into square wave outputs.

The number and types of outputs are based on an integrated micro-controller and a factory installed program. Various programs were developed to meet the specific needs of different applications. Many programs offer installation time options that are configured using DIP switches located near the connector.

The following are examples of existing program outputs and features:

User selectable pulses per revolution (ppr)
User selectable output circuit
2 or 3 pulse outputs with differing pulses per revolution
User selectable quadrature outputs
Anti-jitter and enhanced anti-jitter features
Direction indicator
Minimum speed detector
Fractional pulses per revolution, such as 2.5 ppr
Multiplier that increases the maximum ppr

Programs:

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

Typical Program Features:

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

Anti-jitter: Increases the pulse hysteresis to ½of a pulse width, eliminating the effects of mechanical vibration and the possible dither that results in false output pulses. For example a 10 pulse per revolution output would have 18° hysteresis (i.e. 360° ÷ 10 × ½).

Direction Indicator: Indicates direction of shaft rotation.

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

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