Product Description:
The EA170-35100 Limit Switch part of the Snaplock Limit Switches series is engineered for high reliability industrial automation applications. Danaher manufactured this module and it is for critical control and safety systems.
The EA170-35100 limit switch die-cast zinc housing combined with a stainless steel top cover and fasteners enhances the switch's durability and corrosion resistance, making it suitable for harsh environments that include those with chemical exposure. It is included with open conduit entrance (302) and a 9 pin connector (402) which provides flexibility in wiring configurations. The EA170 Series Snap Lock limit switch operates using a double pole, double throw (DPDT) rocker type action which means it can control two independent circuits and provide both normally open (NO) and normally closed (NC) contacts. It is seismic and vibration resistant which means it can withstand strong shocks and mechanical disturbances and it is also designed to resist chemical sprays and harsh environments. This model actuator pre travel is 10° for standard versions and 6.5° for short travel versions and its maximum travel is approximately 37° which indicates the extent of movement before mechanical limits are reached.
The EA170-35100 limit switch supports 125 VDC at 5 A and 250 VDC at 1.5 A which makes it capable of handling moderate DC loads in control circuits. This module comes with butt contacts which are made of silver alloy and gold plated and ensures electrical resistance and high reliability crucial for consistent performance over long periods. With a mass of only 3.5 lbs it is sturdy and heavy duty which suggests it is built for rugged industrial applications rather than lightweight or delicate setups.
Frequently Asked Questions about EA170-35100:
Q: How does the DPDT rocker-type action in the EA170-35100 Limit Switch improve circuit control?
A: The DPDT rocker-type action allows the switch to control two independent circuits simultaneously. This ensures redundant or dual-functionality operations, enhancing safety and reliability.
Q: Why is gold-plating used on the EA170-35100 Limit Switch’s silver alloy contacts?
A: Gold plating minimizes oxidation and resistance buildup, ensuring reliable electrical performance. This enhances the contact life span and maintains low resistance for critical control applications.
Q: How does the seismic and vibration resistance of the EA170-35100 Limit Switch benefit industrial applications?
A: It ensures the switch remains operational under extreme conditions, preventing malfunction due to external forces. This makes it ideal for nuclear, automation, and heavy machinery applications.
Q: What advantage does the EA170-35100 Limit Switch’s stainless steel top cover provide over other materials?
A: The stainless steel top cover enhances durability and resists chemical corrosion. This allows the switch to function in environments exposed to harsh chemicals or extreme weather conditions.
Q: How does the adjustable lever in the EA170-35100 Limit Switch contribute to flexibility in automation systems?
A: The lever can be adjusted in 7°30’ increments, allowing precise actuation settings. This ensures optimal placement and function in complex industrial automation setups.
