Namco EA170-12100 Snap Lock Limit Switch

Namco EA170-12100 Snap-Lock Limit Switch is a rugged, double-pole, double-throw (DPDT) limit switch with a rotary Snap-Lock actuator designed for harsh industrial environments and machine tools. The unit provides two normally open and two normally closed contacts (2NO/2NC) and is configured for CCW operation on this variant, aligning with Namco’s EA170 Snap-Lock lineup. The Snap-Lock architecture keeps the electrical and mechanical sides in separate enclosures, delivering quick make/break action and secure latching in either open or closed position, while the enclosure family meets NEMA 1, 4, and 13 ratings for dust, splash, and oil exposure. Namco’s EA170 series is offered in standard, wide, and long mounting configurations with CW, CCW rotation options; EA170-12100 corresponds to CCW rotation with a standard rotary actuator. Electrical ratings cover a range of AC and DC voltages: for AC, 125 VAC up to 20 A, 250 VAC up to 15 A, and 480 VAC up to 10 A; for DC, 125 VDC up to 5 A and 250 VDC up to 1.5 A, with 600 VDC listed at 5 A in some datasheets. Typical applications include machine tools, conveyors, and safety interlock circuits where a robust, fail-safe limit switch is required in standard industrial environments. This specific EA170-12100 is the CCW-rotating variant suitable for standard mounting within Namco’s Snap-Lock EA170 family.
