Schmersal Solenoid Interlock Switch MZM 100 Series Power to Lock 24V DC 1A 2 PNP Contacts MZM 100 ST2-SD2PREM-A

Schmersal MZM 100 ST2-SD2PREM-A is a solenoid interlock switch designed with power to lock functionality, operating at 24V DC and rated for a 1 amp contact current. This switch provides enhanced safety by securely locking guard doors, preventing accidental exposure to dangerous moving parts in industrial machinery.

The device features 2 PNP safety contacts and utilizes a coded actuator type to ensure precise safety monitoring. Its housing is constructed from glass fibre-reinforced thermoplastic, offering excellent resistance to heat and impact stresses commonly found in industrial environments.

It complies with internationally recognized standards including IEC 61508, EN ISO 13849-1, CE, and cULus, while also conforming to EN 60947-5-1, BG, and IEC 60947-5-3 certifications. The IP65 and IP67 ingress protection ratings guarantee dust-tight construction and resistance to immersion in up to 1 meter of water for 30 minutes, making it suitable for demanding industrial settings.

The switch achieves a maximum reaction time of 150 milliseconds, enabling rapid detection and response to safety events. It has a robust mechanical lifespan exceeding one million switching cycles, assuring reliability over extended service periods.

The MZM 100 ST2-SD2PREM-A tolerates initial misalignment of ±5 mm vertically and ±3 mm horizontally between the actuator and the switch, facilitating easier installation even on less precise guard doors.

With compact dimensions measuring 179 mm width, 40 mm length, and 40 mm depth, this industrial safety device is well-suited for integration into various machinery. It is manufactured in Germany, confirming high-quality engineering and production standards.

Key industrial applications include semiconductor manufacturing lines, bottling plants, conveyor systems, and textile industry equipment where safeguarding personnel from hazardous machinery operation is essential.

The switch operates on a 24V DC supply voltage with a contact current rating of 1 amp. Glass fibre-reinforced thermoplastic housing for durability and resistance to heat and impact. IP65 and IP67 rated for dust and water ingress protection.

Certified to IEC 61508, EN ISO 13849-1, CE, and cULus standards. Maximum reaction time of 150 ms for rapid safety signal response. Robust mechanical lifespan exceeding one million cycles. Allows door misalignment tolerance of ±5 mm vertically and ±3 mm horizontally.

Compact size of 179 mm width by 40 mm length by 40 mm depth. Does not include actuator; compatible actuator (RS Stock No. 880-1909) must be ordered separately. Explore the full range of Schmersal Safety Interlock Switches on EnvMart to find perfect solutions for your industrial safety requirements.
