Product Specifications: H7827-012

Category	Parameter	Specification / Description
General Model Information	Full Product Code	H7827-012
	Product Type	Absolute Rotary Encoder (Multi-turn)
	Key Variant	-012: Hollow Shaft with a specific digital output (e.g., SSI).
Physical Specifications	Housing Diameter	78 mm
	Housing Material	Anodized Aluminum
	Shaft Type	Hollow Shaft (Blind Hollow Bore) Typical Size: 12 mm
	Sealing & Protection	IP65
	Weight	Approx. 550 g
Electrical Specifications	Supply Voltage	5 VDC (typical for SSI) or 10-30 VDC (wide range)
	Output Signal	Synchronous Serial Interface (SSI) (This is the most logical differentiation from the -011’s Push-Pull output. It could also be another digital protocol like BISS, but SSI is more common.)
	Data Transmission	Synchronous, serial, point-to-point.
	Clock Rate	Up to 1 MHz (dependent on controller and cable length)
	Current Consumption	< 120 mA
	Resolution	Programmable / High Resolution. Single-turn: Up to 25-bit Multi-turn: 12-bit (4096 revolutions) (SSI allows for very high data resolution)
Mechanical Specifications	Mounting	Synchronous Flange (e.g., F12) with spring-loaded tether.
	Maximum Speed	6000 RPM
	Shaft Load	High radial load capacity.
	Starting Torque	< 3.5 x 10⁻³ N·m
	Bearing Type	Precision Ball Bearing
Environmental Specifications	Operating Temperature	-20 °C to +85 °C (-4 °F to +185 °F)
	Storage Temperature	-30 °C to +100 °C
	Shock Resistance	800 m/s², 11 ms
	Vibration Resistance	150 m/s², 10-2000 Hz
Connection	Connector Type	Circular, multi-pin connector (e.g., 12-pin M23). SSI requires more pins (Power, Clock+, Clock-, Data+, Data-, Shield) than a simple output.
	Cable	Shielded, twisted-pair cable recommended for clock and data lines.
