® RIM Tach HS85 Features: • Mounts easily to roller, sleeve, or ball bearing motors and can be used on non-motor applications, such as line shafts and conveyor shafts. • Accepts motor shafts sizes up to 4.500” (115mm) dia., including tapered shafts. • Rugged, cast-iron and steel enclosure. • Rugged, zero-speed, magnetoresistive sensing technol- ogy immune to grease, salt water, dust, and other con- taminant. • Designed with heavy duty, double sealed, deep groove, radial ball bearings to tolerate axial and radial runouts. The ©NorthStar RIM Tach HS85 is a mill duty, digital tachometer that accommodates large thru-shaft sizes (up to 4.500” or 115mm) and can easily mount to most AC or DC fan cooled motors. This digital tachometer offers the same reliability, resolution, and flexibility characteristic of NorthStar’s products. The HS85 provides for reduction of downtime and ease of maintenance. Reliable Magnetoresistive Technology Rugged Construction The HS85 digital tachometer incorporates state-of-the-art The HS85 was created as a solution to roller or sleeve bearing magnetoresistive sensing technology. The magnetically encoded motors with excessive axial and radial play. This digital signals provide pulse codes of A, B, and an optional index pulse tachometer is ruggedly designed with steel flanges, heavy duty Z, with complements (A, B, Z). These signals are solid for the motor style bearings, and cast iron housing. The mill duty life of the encoder. They do not exhibit the unreliable signal drift construction is ideal for motor and non-motor applications, or that requires a fault check on other digital tachometers. In where the motor casting is otherwise unavailable. As an example, addition, this technology is immune to common contaminants the HS85 is perfect for mounting as a line shaft reference such as water, oil, grease, dirt, vibration, and overall harsh encoder. By virtue of design, the HS85 is more forgiving of older conditions of operation. motors which are unable to hold precise tolerances. Easy Installation The HS85 is shipped pre-assembled. The installation is quick and easy; just slip the unit over the motor shaft, tighten the clamp, and add the anti-rotation arm. The sensor alignment of the HS85 is entirely independent of the motor frame. Wiring is simple due to the industrial duty connectors. No field soldering or crimp pins are required. Simply strip conductor ends, insert and tighten the connector screws. The interchangeable stainless steel sensor modules are available in a wide variety of pulse counts. There are no field gap checks, axial alignments, or radial run-out checks required. ©NorthStar Technologies, Inc. /A LakeShore Company 575 McCorkle Blvd., Westerville, OH 43082 Tel:(614) 818-1150 Fax:(614) 891-6909 www.northstar-tec.com sales@northstar-tec.com 791-7008-00 Rev. 2 service@northstar-tec.com Electrical Specifications Ordering Information 60, 64, 75, 120, 128, 150, 240, 256, 300, 480, 480Z, 512, 512Z, 600, Resolution AAAA Tachometer Type 600Z, 960, 960Z, 1024, 1024Z, 1200, 1200Z, 2048, 2048Z HS85 HS85 0 - 120 kHz Frequency Response HS85 Quad Output HS85Q Pulse Code A, B, Z (Index), and complements (A, B, Z) BBBB Pulse Count Output Phases A phase, B phase @ quadrature 90°; Z phase: One per rev.
