 SLIM Tach® SL1250 Incremental Encoder
Quick Specs...
- Mounts to NEMA 12.5 inch C face motor
- Thin, compact, and occupies only 1.4 inches of motor shaft
- Rugged, reliable, magnetoresistive technology
- Easy installation with no brackets or couplings
- Hard, anodized aluminum construction
Overview / Design Principle:
Employing NorthStar’s innovative magneto-resistive technology, this
dependable product combines high accuracy with reliable service. Made of anodized
aluminum and with a net thickness of only 1.4 inches, the SLIM Tach® SL1250
comes with one or two electrically independent and totally isolated output
modules and a high temperature version for operation needs up to 120° C.
The SLIM Tach® S1250 assembly is imprinted with magnetic poles, providing
higher pulse counts than traditional encoders. Its totally encapsulated electronics
make it immune to machine vibration and contaminants. It is resistant to dirt,
grease, water, oil, fibers, and dust, making it reliable in hot, wet environments.
A high power line driver comes standard. Clean, crisp signals are ensured over
long cable lengths, decreasing the need for signal repeaters and saving on
total installation costs.
The SLIM Tach® 1250’s pulse wheels are available in thru-shaft sizes
from 0.625 inch to 3.75 inches. The pulse wheels are keyless and very easy
to align. The SL1250’s thin profile leaves plenty of room on the motor
shaft for a brake or pulley and it mounts without bearings, adapter plates,
or couplings, eliminating a common source of mechanical problems.
Features and Benefits:
- Thru-shaft sizes from 0.625 to 3.75 inches
- 64, 128, 256, 512, or 1024 pulses per revolution (PPR) with optional
index pulse
- 5-15VDC operation, bi-directional quadrature signals with high power,
differential line driver outputs
Applications:
NorthStar’s SLIM Tach® 1250 is an economical, bearingless, heavy
duty encoder designed for 12.5 inch C face motors. Available with resolutions
to 1024 PPR. Specifications:
