Safety Interlock Switch with Solenoid Lock

The Banner SI-LS42DMG is a safety interlock switch designed for machine guarding applications. It features a solenoid lock and spring unlock mechanism with one normally closed and one normally open contact for actuator monitoring. The switch operates on 24 V ac/dc and provides an IP67 rating for harsh environments. Its thermoplastic housing measures 170 x 43 x 45 mm.

Suitable for Category 4 Safety Systems

This switch suits safety circuits requiring PL e and SIL CL 3 ratings with a B10d value of 2 million operations. It is not for applications needing auxiliary outputs or cascade capability with ISD devices. Buyers who need a non-locking guard switch or a different coding level should look elsewhere. The 1500 N extraction force suits robust guarding requirements.

Solenoid Locking with 24 V Operation

The defining specification is the power-lock, spring-unlock mechanism operating at 24 V ac/dc with 4.4 VA power consumption. This determines how the guard locks when energised and releases on power loss. The wiring chamber connection and 1 NC/1 NO contact pairs for both safety and monitoring complete the critical interface.

Questions about this item

Which size interlock switch fits a 170 x 43 x 45 mm mounting envelope?

The SI-LS42DMG body measures exactly 170 x 43 x 45 mm, matching that footprint.

What does the 24 V ac/dc rating mean for daily operation?

The switch runs on 24 V ac/dc, drawing 4.4 VA steady and 12 VA for 0.2 s at power-up.

How does the IP67 rating limit where the switch can be installed?

IP67 protects against dust ingress and temporary immersion, so the unit suits wet, dirty machine zones.
