EM14A0D-B28-L008S Description

Short technical summary and product information.

The Bourns EM14A0D-B28-L008S is a 14 mm rotary optical encoder designed for human-machine interface (HMI) applications. It provides a 2-bit quadrature code output with a resolution of 8 pulses per revolution (PPR).

 

This encoder operates with a supply voltage of 5.0 VDC ± 0.25 VDC and has a maximum supply current of 26 mA. It features HCMOS, CMOS, and TTL compatibility, ensuring broad integration possibilities. The device includes a built-in push switch and has a rotational life of at least 1 million cycles.

 

Designed for panel mounting, the EM14A0D-B28-L008S has a slotted shaft type with a diameter of 6.35mm. Its compact package size and vertical orientation make it suitable for space-constrained designs. The operating temperature range is from -40°C to 70°C, and it has an IP54 rating for environmental protection.

 

Key electrical characteristics include a maximum output voltage low of 800 mV and a minimum output voltage high of 4.0 VDC. The rise/fall time is typically 200 ns. The encoder's insulation resistance is a minimum of 1,000 megohms at 500 VDC.
