The NorthStar HD25 high-performance heavy duty incremental rotary encoder, constructed of aluminium or high-grade stainless steel, is capable of operating at extreme temperatures. In addition, the NorthStar HD25 is able to withstand excessive radial and axial loading.

The HD25 encoder, due to its unbreakable disk can tolerate applications where considerable shock and vibration can occur. The unique double-sealed labyrinth housing prevents the ingress of contaminants, designed to exceed IP67 protection class ratings.

The HD25 encoder housing is 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.

Mounting options are a square flange. Encoder resolutions up to 5,000 pulses are available with a shaft diameter size of 9.52mm (3/8”), 10mm and 12mm, and shaft protection class ratings of IP67.

Optional 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 HD25 encoder is available, certified to ATEX EEx ia IIB T4 when used with an appropriate intrinsic safety barrier.

Value, quality and reliability are built into every HD25 encoder.
