Product Description:

The HS35010042215 is a hollow-shaft incremental encoder produced by Danaher under the Dynapar Encoders series. Designed for feedback loops in industrial motion systems, it mounts directly on a drive or load shaft and converts rotation into digital pulses that a controller can count for speed or position regulation. The through-shaft architecture saves space and simplifies alignment, making the unit suitable for conveyors, packaging stations, and general automation equipment where compact sensing and straightforward installation are required.

Mechanical mounting centers on a bore of 3/8 in, and a fixing bolt circle of 7.25 in secures the stator arm to adjacent hardware. The aluminum housing carries NEMA 4 / IP66 enclosure ratings, keeping water jets and airborne dust away from the code wheel. Internal electronics draw up to 100 mA, placing a modest load on shared low-voltage supplies. The open-collector driver supports line rates of at least 100 kHz, so edge detection remains accurate at high mechanical speeds. Resolution is fixed at 100 PPR, providing 3.6-degree increments per pulse before any additional counting through quadrature decoding. This resolution balances data throughput with processing requirements in moderate-speed motion-control loops.

A fixing hole with a diameter of 1/2 in accepts a standard fastener to hold the tether clamp during dynamic operation. A built-in pull-up network with a resistance of 2.2 kΩ biases the output channel, eliminating the need for external resistors when the encoder interfaces with compatible TTL or CMOS inputs. The rotating assembly tolerates continuous operation at speeds up to 3600 rpm. Running torque is limited to 4.5 oz-in, while starting torque is limited to 5.0 oz-in, helping reduce back-drive forces on small motors. Connection is provided through a 6-pin plug, and a mating connector is supplied for integration with the host system. The complete encoder weighs no more than 16 oz, reducing the overhung load placed on the host shaft.
