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

The Model RS-P is a shaft encoder in a standard 2¼” cube shaped housing that is electrically and physically interchangeable with most available cube style encoders. When coupled to a rotating shaft it generates up to 3 square wave outputs depending on a factory installed program and options, and on DIP switch positions set at installation time.

The types of outputs based on shaft rotation are as follows:

Pulse Output: A Single output (A) with a specific number of counts per revolution (cpr) of the shaft; Dual outputs (A and B) with two independent outputs and the cpr on A can be different than the cpr on B; or Triple outputs (A, B, and C) with three independent outputs.

Quadrature: Two pulse outputs, A and B, have the same cpr and are in quadrature relation to each other (A leads B by 90 for clockwise rotation as viewed from shaft end farthest from connector). This will indicate distance and direction of shaft rotation to any control device that accepts quadrature inputs.

Zero Marker Output: Provides a zero reference or index pulse on output Z occurring once per revolution, having a pulse width approximately equal to a pulse on output A.

Direction Output: Indicates the direction of shaft rotation, clockwise or counter-clockwise.

Minimum Speed Output: Indicates when the shaft exceeds a predetermined revolutions per minute (rpm).

Anti-Jitter feature: Designed for conveyor and web systems requiring continuous and accurate measurement of the web’s movement even if the system must be stopped and restarted without reset. When the web stops, and if there is sufficient vibration or back-and-forth movement, then the encoder output could oscillate, appearing as if the web were actually moving. Anti-jitter eliminates this condition by significantly increasing the pulse hysteresis.

Accessories

Cable Assembly (C6-x-10): 10ft. (3m) shielded cable with 97-3106A14S-6S connector (x is the number of conductors)
Other lenghts are avilable.
CE mark requires Photocraft cable, and surge protection if cable exceeds 100' (30m) or leaves the building.

Flexible Copuling: aluminum helical coil style copuling for shaft to shaft connections.
AE087-10-10: 5/16" shaft size .875" diameter X 1" length
AE100-12-12: 3/8" shaft size 1" diameter X 1.25" length

Installation Instructions

1. Mechanically mount the encoder.
Use a flexible shaft copuling to compensate for axial and angular misalignment.
2. Attach the cable leads to the control device (e.g. PLC) ensuring that the power supply meets specifications.
3. Set the configuration switches.
Switches can be changed at any time.
4. Attach the cable to the encoder.
