SM2X1220 Lovato side mount auxiliary contact 2no

Why Choose the SM2X1220?

The Lovato SM2X1220 is an add-on auxiliary contact accessory designed for side mounting on SM2R... and SM3R... devices. This 2NO module extends signalling and control without altering your main device functionality. With a rated insulation voltage of 690 V and 4 kV impulse withstand, the SM2X designation delivers robust performance in industrial control applications, backed by Lovato engineering and compliance to key international standards.

Built for reliability, it offers 100000 mechanical life cycles and operates from -20 to +70 °C, with storage from -50 to +80 °C and use up to 3000 m altitude. Terminal tightening torque is 1 to 1 Nm, and the compact 40 g build aids panel layouts. Conforms to IEC/EN 60947-1 and 60947-5-1, plus UL508 and CSA C22.2 n° 14.
