SLIM Tach® HS56 Incremental Encoder / Tachometer
- For Fan Cooled and Non-Motor Applications
- Hollow shaft design allows for a variety of possible mountings; ideal to retrofit AC fan cooled motors.
- Rugged, zero-speed, magnetoresistive sensing technology is immune to grease, salt water, dust, or other common contaminants.
- Up to 80° C operation
Overview / Design Principle:
The SLIM Tach® HS56’s magnetoresistive sensor technology is virtually immune to common contaminants such as grease, oil, water, and dirt. Hardened encapsulated electronics make it especially resistant to heavy machine vibration and accidental impacts. Advanced electronic design offers many features such as operation from 5-26 volts DC power, short circuit protected outputs, and EMI noise resistance. High power complimentary line driver outputs assure clean, crisp signals over long cable lengths.
A stainless steel and hard anodized aluminum alloy frame provides exceptional strength, ruggedness, and superior corrosion resistance. Its extra heavy duty bearings are designed to maximize its operational life. Since the entire encoder rides on large motor style bearings, the unit can tolerate considerable shaft movement. A strong, insulated, stainless steel anti-rotation arm with multiple mounting holes allows the encoder to move axially, radially, and at a tangent. The simple prealigned design of the HS56 does not require user adjustments.
Easily mounted on fan-cooled motor shafts, conveyor equipment, assembly machines, material feeders, pumps, hydraulic equipment, and gear boxes, the SLIM Tach® HS56 does not require mounting flanges or accessory brackets. If a suitable shaft is not available, a stub shaft installed through the fan shroud into the motor shaft provides a means of easy mounting.
The SLIM Tach® HS56 is also available in with electrically isolated dual outputs. Each output can be operated at different voltages and/or sent to different locations. The dual outputs can be used for security with encoder redundancy. A failed output can be quickly switched to the second output, thereby reducing downtime. Our accessory Intellitach ™, can continuously monitor the encoder feedback, and automatically switch outputs in the case of signal failure.
Features and Benefits:
- Combines rugged reliable feedback with a flexible mounting design. Fits 0.625 – 1.125 inch shaft sizes
- 64, 128, 256, 512, 1024, or 2048 pulses per revolution (PPR) with optional index pulse
- 5-26VDC operation, bi-directional quadrature signals. Short circuit protected, high power line drivers are available
The NorthStar brand SLIM Tach® HS56 has been designed especially for maintenance, motor repair, and field personnel. It offers an unparalleled means of applying a leading edge digital encoder to motors and other devices that require an innovative method of installation.
