Hollow Shaft Encoder - HS25-P Series
HS25-P - User Selectable Pulses per Revolution
The model HS25-P is an optical hollow shaft encoder in a 2-1/2" diameter housing that mounts directly on an existing shaft assembly. An anti-rotation pin or flexible mounting bracket allows the encoder to float on the shaft without rotating. The HS25 generates up to 3 square wave outputs. The number of pulses per revolution is determined by setting configuration switches accessible through an access port on the face of the encoder. Any one of a predefined set of pulses per revolution are available.
Standard Features and Options:
• Fits shafts up to 3/8" (9.5mm) diameter
• Up to 600 pulses per revolution (ppr)
• Optional User selectable ppr
• Single, quadrature, and index outputs
• Direction or speed indicator output options
• Exclusive "Anti-Jitter" option
• Output Circuits: Current sinking (NPN), Current sourcing (PNP), Push-Pull, NPN open collector
• ESD and short circuit protection
• 5 vdc, 8 to 30 vdc, and other supply voltages

INSTALLATION NOTES
- Slide the HS25 onto the shaft and tighten set screws. Be sure to maintain clearance around the entire encoder body.
- Use the anti-rotation screw, flexible mounting bracket, or other means to prevent the encoder from rotating.
- Attach the cable leads to the control device (e.g. PLC) ensuring that the power supply meets specifications.
- Attach the cable to the encoder
