LONG FELLOW II SERIES LINEAR POSITION TRANSDUCER APPLICATIONS LONGFELLOW II LINEAR POSITION TRANSDUCER The new Longfellow II has a rugged long-life design featuring greater INJECTION resistance to vibration and a smooth high quality signal. It has a solid stainless MOLDING steel shaft, longer front-end bearings, a vibration-free damped element, MACHINES a spring-loaded ball joint and a high precision precious metal wiper. Carrier PRINTING guides extruded the full length of the housing insure smooth operation PRESSES even under severe side load conditions. The Longfellow II is a direct drop-in replacement for existing Waters, MEAT PACKING EQUIPMENT Data Instruments, Novotechnik, Gefran or Sfernice units. The newly designed internal components provide improvements which were DRILL developed after worldwide testing and field experience. PRESSES Intrinsically Safe for Class I, II, and III Division 1, Groups A, WOODWORKING B, C, D, E, F and G for Hazardous (indoor/outdoor) MACHINES NEMA 4 locations. V max = 30 V, I max = 100 mA, Ci = 0, uF, Li, = 0 mH. CRANES FRONT-END LOADERS SCALES SEMI CONDUCTOR PROCESSING FEATURES BENEFIT Vibration damped element No wiper bounce in high vibration Environments Spring-loaded ball joint assembly Operation under high side loads Extruded wiper carrier guides Smooth operation under large misalignment Precious metal wipers Insures high performance, low noise, no oxidation MystR plastic elements Tested up to one billion operations High DC level output Works with simple controllers High performance bearings Long life under side load conditions Absolute continuous measurement Accurate position at power-up Shaft seals Protect internal components from environments LF2W NEMA 4 and water resistant HOW TO ORDER LF2S 06 N 5K B 6 A Model Termination LF2S = Standard A = Binder LF2W = Water Resistant Shaft 6 = 1/4 - 28 Thread Electrical Travel 06, 09, 12, 14, 18, 24, 30, 36, 48 Linearity B = 0.1% Unit of Measure Total N = Inches Resistance 5K = 5000 Ohms (Ohms) Note: Not all combinations are available.
