US DigitalHD25-1000-N-S-H-NE-SIncremental Optical Shaft Encoder — NEMA Size 25, 1000 CPR, Sealed IP65, 9.5-30 VDC, Single-Ended, No Index, With 7-Pin Cable

Product Description

What this part is

The US Digital HD25-1000-N-S-H-NE-S is a rugged incremental optical shaft encoder in the industry-standard NEMA size 25 package. It outputs two-channel quadrature squarewave signals for position and speed feedback. This listing includes a US Digital CA-RC7-SH-NC-100 shielded cable.

Decoding the designation

HD25 — US Digital heavy-duty size 25 incremental shaft encoder.

1000 — 1,000 cycles per revolution (4,000 pulses per revolution in quadrature).

N — non-flat shaft.

S — sealed housing, IP65.

H — high-voltage version, 9.5 to 30 VDC.

NE — no index channel.

S — single-ended output.

CA-RC7-SH-NC-100 — 7-pin MIL-DTL-5015 female connector to flying leads, shielded cable, 100 ft length code.
