SM2X1120 Lovato front mount auxiliary contact 2no

Why Choose the SM2X1120?

Designed for seamless signalling expansion, the Lovato SM2X1120 add-on auxiliary contact delivers two normally open contacts in a convenient front-mount form. Compatible with SM2R and SM3R devices, this accessory integrates cleanly into control assemblies. With a 250 V rated insulation voltage and 4 kV impulse withstand, it provides robust performance for industrial control applications while keeping installation simple and reliable.

Built for longevity and compliance, the SM2X series module achieves 100000 mechanical cycles and operates from -20 to +70 °C, up to 3000 m altitude. A light 20 g profile and 1 to 1 Nm terminal tightening torque aid quick, secure fitment. Conformity with IEC/EN 60947-1 and 60947-5-1, plus UL508 and CSA C22.2 n° 14, supports dependable, audited installations.
