XCSD3919N12 Telemecanique Sensors Safety Switches

Telemecanique XCSD3919N12 is a safety limit switch with rotary movement and snap action. It is part of the XCSD sub-range and features a rated impulse voltage (Uimp) of 4 kV. The switch is constructed with a steel roller, and both the head and body are made of Zamak. It offers a 1/2" NPT cable entry connection type and provides a degree of protection rated at IP66 and IP67. This model is designed for mechanical durability of up to 10,000,000 operations at no load and has 3 poles, including 1 Normally Open (NO) auxiliary contact and 2 Normally Closed (NC) auxiliary contacts. The rated insulation voltage (Ui) is 400 V for UL and 300 V, with a control circuit rated current of 1.5 A at 240Vac (AC-15), 100mA / 0.1 A at 250Vdc (DC-13), 1.5 A at 240Vac (B300), and 100mA / 0.1 A at 250Vdc (R300). It operates within a temperature range of -25°C to 70°C, has an electrical durability (with load) of 5,000,000 operations at 240Vac/250Vdc, and requires an operating torque of 0.1 N.m.
