HSD37 | ISD37 Extreme Heavy Duty Incremental Rotary Encoder

The NorthStar HSD37 high-performance extreme heavy-duty through hollow shaft incremental rotary encoder, constructed of aluminium or high-grade stainless steel, is manufactured to endure the most volatile working conditions including, prolonged operation, extreme temperatures, excessive shock and vibration.

The HSD37 encoder, due to its high-resolution unbreakable disk can tolerate applications where considerable shock and vibration can occur. The unique double-sealed housing prevents the ingress of contaminants, designed to exceed IP66/IP67 protection class ratings.

The HSD37 encoder housing manufactured from hard anodised aluminium with an optional nickel finish. Stainless steel housing that is particularly suited to applications where high resistance to corrosion or high-pressure washdown environments such as food preparation areas is also available.

The encoder features simple connectivity to the driveshaft by a front clamping ring. Optional spring fasteners are provided to secure the encoder to a flat surface to compensate radial or axial shaft misalignment.

Encoder resolutions up to 5,000 pulses are available with metric shaft diameter sizes of 6mm, 8mm, 10mm, 12mm, 15mm, 16mm, 19mm, 20mm and 25mm, imperial shaft sizes of 1/4”, 5/16”, 3/8”, 1/2”, 5/8” 3/4”, and 1”, and shaft protection class ratings of up to IP67.

Cable outlets and connectors are radial. An optional double connector provides simultaneous electrically isolated outputs for applications that require two output signals to monitor speed and position from one encoder. The supply voltage is 5V to 26V DC; output signals are push-pull with or without complementary signals.

An intrinsically safe version of the HSD37 encoder is available, ISD37, certified to ATEX EEx ia IIB T4 when used with an appropriate intrinsic safety barrier.

Value, quality and reliability are built into every HSD37 encoder.
