Built to Last: Materials & Construction
The E-Series is engineered for demanding environments:
Housing Options: SUS304 stainless steel, brass with nickel plating, or anodized aluminum alloy
Key Material: Polycarbonate + SUS316 stainless steel
Base Material: Modified nylon PA66 for high heat and impact resistance
Contact Material: Silver tin oxide alloy – excellent anti-welding and anti-erosion properties
Pin Style: Switch pins (3.5×0.5mm) + LED pins (2.8×0.5mm)
✅ These materials ensure corrosion resistance, mechanical strength, and stable electrical contact over thousands of operations.
Flexible Operating Modes & Switch Combinations
The E-Series supports:
Work Forms: Self-locking or self-resetting (momentary) – field-selectable
Switch Combinations: 1 Normally Open (NO) + 1 Normally Closed (NC)
LED Polarity Options:
Single color (non-polarity)
Two colors (non-polarity)
Three colors – Common Anode (COM+) or Common Cathode (COM-)
LED Lighting – Customizable & Visible
Available LED voltages include:
AC/DC: 3.3V, 6V, 9V, 12V, 24V, 36V, 48V, 110V, 220V
Current Range: 2mA ~ 20mA
Colors: Red, Green, Blue, Yellow, Orange, White, Purple, Pink, and multi-color options (e.g., RG, RB, RGB, RGY)
💡 Multi-color LEDs can be customized to indicate different machine states (standby, running, error).
Electrical Safety & Compliance
Insulation Resistance: ≥100 MΩ @ 500 VDC / 1 min
Dielectric Strength (Pins to Housing): 2500 VAC @ 20 mA / 1 min
Contact Configuration: 1NO1NC allows flexible integration into safety circuits.
