Program Details

The model HRS-P is an incremental shaft encoder with up to a 1.000" (25mm) blind shaft bore in a standard 2.250” cube shaped housing that is electrically interchangeable with most cube style encoders on the market. It is designed to mount directly on an existing shaft. A flexible mounting bracket allows the encoder to float on the shaft without rotating. The HRS generates up to 3 square wave outputs that are either fixed at manufacture time, or based on a factory installed program and on DIP switch values set at installation time. The types of outputs are based on shaft rotation 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). Indicates 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: is 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), x condustor shielded cable & connector
Other lengths are available.
CE mark requires Photocraft cable, and surge protection if cable exceeds 100' (30cm) or leaves the building.

Flexible Mounting Bracket (MB-FB1): flexible stainless steel that allows for axial and angular shaft misalignment

Mounting Instructions

Slide HRS onto shaft, fasten flexible mounting bracket or tether to frame, and then tighten shaft set screws.
Atach the cable leads to the control device (e.g. PLC) ensuring that the power supply meets specifications.
Attach the cable to the encoder.
