Product Description:

The Dynapar Encoder HS35R1200P379 is used to provide high-performance and precise signal output in demanding motion control applications. Manufactured by Danaher, this encoder delivers an output of 1200 pulses per revolution (PPR). This high-resolution output allows accurate motion feedback in various control systems.

This encoder is designed with a differential ABZ output along with a 7272 line driver to accept a wide voltage range of 5 to 26 VDC input. The output voltage of this encoder is also the same to allow flexible integration without any additional converters or regulators. This dynapar encoder has a bore size of 25 mm and is engineered to suit standard shaft diameters in industrial machinery. The material of the shaft is 6061-T6 aluminum, which possesses high strength, light weight, and corrosion resistance. The maximum allowable shaft speed of this encoder is up to 6000 RPM to make it applicable for applications with high-speed rotation. The enclosure rating of this encoder is IP67, and it changes to IP64 when the shaft speed is higher than 5000 RPM. This IP rating offers protection against dust and splashing water, while at the same time guaranteeing performance integrity.

The HS35R1200P379 dynapar encoder incorporates a slotted tether fixing mechanism for secure installation. This fixing also allows the shaft to rotate freely, hence minimizing the tendency to mechanical slippage or misalignment. The default width of the index signal for this encoder is set to 180° to create a wide signal window for precise referencing. The electrical connectivity of HS35R1200P379 dynapar encoder uses a 10-pin bayonet connector, which includes a mating connector for immediate plug-and-play installation. This connectivity reduces installation time while eliminating any chances of wire detachment under high vibration.

Frequently Asked Questions about HS35R1200P379:

Q: Why does the HS35R1200P379 encoder include a 180° index pulse width?

A: The wide 180° index allows more flexible signal timing, enabling accurate referencing in positioning and homing operations.

Q: How does the slotted tether in HS35R1200P379 help minimize mechanical wear?

A: It holds the encoder securely while allowing slight axial movement, reducing stress from shaft misalignment and lowering mechanical wear.

Q: How does the 10-pin bayonet connector improve the usability of the HS35R1200P379 encoder?

A: It allows quick plug-and-play installation with secure locking, ensuring stable connections even in high-vibration environments.

Q: Does the encoder HS35R1200P379 support quadrature decoding?

A: Yes, with its differential ABZ output, it supports quadrature decoding, which is essential for direction sensing and resolution enhancement.

Q: What happens to the enclosure rating of HS35R1200P379 at speeds over 5000 RPM?

A: It drops from IP67 to IP64 due to increased shaft pressure and reduced sealing effectiveness at higher rotational speeds.


Internal Product Review

  • ‘‘The HS35R1200P379 Dynapar Encoder stands out with its IP67-rated sealing, 10-pin bayonet connector, and wide 180° index window. The slotted tether prevents shaft misalignment during high-speed rotation. With a voltage range of 5–26 VDC, it's perfect for rugged automation setups needing consistent feedback.’’
