Rotary Mill Duty Heavy Duty Industrial Duty Light Duty Absolute Instrument Linear Accessory Display Controller ® SLIM Tach SL56 Bearingless Heavy Duty Encoder The bearingless, heavy duty, NorthStar SLIM Tach SL56 has been designed to mount directly to 4.5 inch 56 C face motors. With resolutions up to 2048 PPR, it is only 0.75 inch thick and is ideal for tight machine configurations. This reliable encoder may be configured with one or two electrically independent and totally isolated outputs. A high temperature version is available to meet operational needs up to 120° C. It also comes in a wide variety of shaft sizes, cover choices, and connector options. Features: Benefits Thin, compact, and only 0.75 inch thick Mounts to 4.5 inch 56 C face motors Rugged, reliable magnetoresistive sensor technology The durable SL56 operates with unequalled Easy installation with no brackets or couplings resistance to grease, oil, salt water, dirt, Hard, anodized aluminum construction fibers, and dust. Its hardened, encapsulated Single or dual sensor outputs available electronics make it immune to contamination, heavy machine vibration, and accidental impact, decreasing For more information on this product, visit downtime. Hard, anodized aluminum of www.northstarencoders.com and enter: SL56 aircraft quality makes the SL56 the toughest, yet lightest, encoder available. A high power line driver comes standard and guarantees Dimensions 1.86 (47.2) clean, crisp signals over long cable lengths, inches(mm) minimizing the need for signal repeaters. Application Each version of the SL56 is easy to mount, 7.53 (191.3) requiring no bearings, adapter plates, or flexible couplings. Because the SL56 10.79 (274.1) occupies only 0.75 inch of the motor shaft length, a brake, pulley, gear box, or coupling 7.63 (193.8) can also be placed on the shaft. The sandwich version provides double C face mounting for applications which need the 2.75 (69.9) encoder between the motor and another device. 0.74 (18.8) 0.84 (21.3) 2.75 (69.9) 1.92 (48.8) 2.72 (69.1) 5.50 (139.7) 614-818-1150 Toll Free: 877-356-1962 Fax: 614-891-6909 sales@northstar-tec.com SLIM Tach SL56 Specifications SL56 Ordering Information Electrical Call 877.311.4190 for Assistance Pulses Per Revolution 64, 128, 256, 512, 512Z, 1024, 1024Z, 2048, 2048Z (Resolution) A Encoder Types Frequency Response 0 - 120 kHz Single Sensor Output SL56 S560 Output Format A, B phase @ quadrature, Z (index) phase once per Dual Sensor Output SL56 D560 rev (gated), and complements (A,B,Z) B Pulses Per Revolution Pulse Duty Cycle 50 + 15% (within defined mechanical specifications) 64, 128, 256, 512, 512Z, 1024, o o Quadrature Accuracy 90 + 22 (within defined mechanical specifications) 1024Z, 2048, 2048Z Output Type High speed, differential line driver Rise and Fall Time Less the 500 ns @ 10,000 pf typical load with C Shaft Sizes 5 - 15 VDC line driver OR 0.625” thru-shaft clamp J04 Less than 1 μs @ 10, 000 pf typical load with 0.875” thru-shaft clamp J05 5 - 24 VDC line driver 1.000” thru-shaft clamp J06 Supply Voltage 5 - 24 VDC 1.125” thru-shaft clamp J07 Current Consumption 40 mA typical plus line driver load with 5 - 15 VDC 1.250” thru-shaft clamp J08 line driver OR 1.375” thru-shaft set screw J09 65 mA typical plus line driver load with 5 - 24 VDC 1.500” thru-shaft set screw J10 line driver 1.625” thru-shaft set screw J11 Current Output 150 mA with 5 - 15 VDC line driver 1.750” thru-shaft set screw J12 OR 1.875” thru-shaft set screw J13 250 mA with 5 - 24 VDC line driver 2.000” thru-shaft set screw J14 Output Voltage Levels Differential output: (Supply Voltage less 0.6V) during 2.125” thru-shaft set screw J15 on cycle, ground during off cycle 2.250” thru-shaft set screw J16 Connector Pigtail, conduit box, latching connector 2.375” thru-shaft set screw J17 See ordering table for options 2.500” thru-shaft set screw J18 Suggested Cable 22 - 16 AWG, 10 conductor, shielded, twisted pair End-of-shaft and custom bore Output Circuit Type 5 - 15 VDC line driver (standard) OR 5-24 VDC line shaft sizes 0.500” to 3.750” driver (optional) available.
