Hongyan Technology EC11H 7CE20P1ZY20 5-Pin Vertical Rotary Encoder with Switch

The Hongyan Technology EC11H encoder is rated for 5 Volts DC with a maximum current rating of 10mA. This makes it directly compatible with standard 5V microcontroller logic levels found on platforms like Arduino Uno, making interfacing straightforward without the need for additional level-shifting circuitry.

The 5 pins typically consist of three pins for the rotary encoder (Common, Channel A, Channel B) and two pins for the integrated push-button switch. The common pin is usually connected to ground, while Channels A and B are connected to digital input pins with pull-up resistors. The switch pins are connected in series between a digital input (with pull-up) and ground. Always consult the specific datasheet for the exact pinout of the EC11H variant.

This encoder is designed for a mechanical and electrical lifespan of 50,000 operating cycles. This rating applies to both the rotational detents and the actuation of the integrated push-button switch, ensuring reliable performance for the typical lifespan of consumer electronics and industrial control interfaces.

While the encoder has a dustproof and waterproof design, its specific IP rating is customizable per customer requirements and is not specified as a standard. For reliable operation in harsh environments, the wide operating temperature range of -35°C to +85°C is a key benefit, but additional external sealing or an enclosure may be necessary for prolonged exposure to liquids or contaminants.
