Product Description:

The EA170-35300 Limit switch is made for limited angular movement in systems that need to reliably detect rotation. The limit switch is made by Danaher, which can be used in industrial control systems that need to be accurate mechanically and stable thermally.

The travel of the EA170-35300 limit switch is 6°30′, and the reset travel is 4°. The limit switch has a short-travel design. It is recommended that the limit switch travel 7°, with a maximum of 36°. The switch can work in temperatures ranging from 0°C to 90°C and can withstand short periods of exposure to temperatures as high as 175°C. The switch is capable of handling both AC and DC voltages. It can also handle 5 A at 120V DC and 1.5 A at 250V DC. The switch is rated for a power factor of 75% to 100%, which means it can handle current well. The EA170 limit switch has high-temperature oils and parts that keep their mechanical integrity even when the temperature changes. The switch can also stand up to chemical spray, which makes it stable in places where chemicals are used. The frame is designed to be resistant to vibration and earthquakes so that it will last for a long time.

The EA170-35300 switch has a mounting configuration called MTG-D2400XSTJ that makes it possible to place it securely in small spaces. The switch can handle 20 A at 120V AC, 15 A at 250V AC, and 10 A at 480V AC. The LS-CCW-ST-HI-T+150C-L MTG-D2400XSTJ model is designed to work with short travel and has precision-engineered parts to make it work well under strict conditions. It is designed to keep working well even after a lot of mechanical cycling.

Frequently Asked Questions about EA170-35300:

Q: How does EA170-35300 achieve chemical spray resistance?

A: It uses sealed components and resistant materials that prevent corrosion and maintain mechanical integrity during chemical spray exposure in controlled setups.

Q: Why does EA170-35300 require 32 in-lbs to trip?

A: The required torque ensures accurate mechanical engagement that prevents false actuation under minor loads or ambient vibrations.

Q: Do EA170-35300 electrical ratings support 480V AC?

A: Yes, it handles up to 10 A at 480V AC that enables reliable performance in higher voltage control systems.

Q: How does EA170-35300 handle vibration resistance?

A: The switch includes reinforced structural elements that reduce sensitivity to vibration and maintain stable contact integrity under cyclic loading.

Q: Why is EA170-35300 configured for 7° recommended travel?

A: 7° ensures accurate switching without overextending internal mechanisms and helps achieve optimal performance across repeated actuations.


Internal Product Review

  • ‘‘The EA170-35300 limit switch delivers a consistent mechanical response with its 7° recommended travel and 32 in-lbs torque to trip. Danaher’s configuration supports 175°C short-term thermal endurance and chemical spray resistance. The LS-CCW-ST-HI-T+150C-L model is optimized for vibration tolerance and controlled angular actuation.’’
