Output circuits include Z□VT, Z□OT, and Z□LT.
Supply voltage is consistent at 4.5 to 5.5V across models.
Maximum supply current varies from 60mA to 90mA.
Signal types include A, B, Z and their differential counterparts.
Rise/fall time ranges from 10ns to 100ns.
Frequency capabilities range from 220kHz to 1.5MHz.
Output voltage levels are 2.4V minimum for high and 0.4V maximum for low.
Maximum output current is 5mA.

Mechanical Specifications

Hollow diameter options are 2, 3, and 4 mm.
Housing material is ABS+PC.
Maximum RPM is 6000, calculated as Frequency * 60 / Resolution.

Environmental Specifications

Operating and storage temperature range is -20 to +85℃.
Operating humidity is up to 85% RH, non-condensing.
Shock resistance is 490 m/s², tested in three directions twice.
Vibration resistance is 1.2mm at 10~55KHz for 30 minutes in three directions.
Protection level is IP 40.

Connection Details

Signal types include A, B, Z with UL2464, AWG26, 5pin + Shield, and A+, A-, B+, B-, Z+, Z- with UL2464, AWG30, 8pin + Shield.
Compatible headers are Molex 532610671 and JST SM09B-SRSS-TB.

Output Waveform
The output waveform is specified for shaft rotation in a counter-clockwise direction, with A leading B.

Output Circuit
Options include voltage output and line driver (AM26C31), as well as open collector configurations.

Ordering Information
Details on ordering include specifications for line driver, voltage output, open collector, TTL, and hollow diameter options.

Cable Introduction
Cable lengths vary depending on the output type, with options of 305mm and 500mm for voltage output/open collector, and 150mm, 305mm, and 500mm for line drivers.

Setting Dimension
Includes axial assembly tolerance, radial assembly tolerance, and concentric angle tolerance.
