Single-position limit switch PEM1G42Z A37-A93Z

Robust Circuit Protection in Demanding Industrial Environments

This single-position limit switch is designed for reliable position detection in automation and machinery. Its metal housing, protected by a powder-coated finish, effectively shields the interior from corrosion and mechanical damage, which is crucial in production environments. The IP67 protection rating ensures the device is not only dust-tight but also resistant to temporary immersion in water, allowing installation in areas exposed to moisture or direct washing.

Precise Control and Safe Disconnection

A key feature of this model is the forced opening function, which ensures safe and rapid circuit interruption even in the event of mechanism jamming. This allows installers to rely on high reliability during emergency situations. The device is equipped with a roller lever that facilitates activation upon contact with moving machine parts. The "momentary contact" switching function enables precise recording of passage through the limit point.

Inside, the configuration includes 1 normally open (NO) contact and 1 normally closed (NC) contact, providing flexibility in control circuit design. The rated operating current (Ie) is adapted to various voltages and load types:

• For alternating current circuits (AC-15): up to 3 A at 125 V or 1.5 A at 230 V.
• For direct current circuits (DC-13): up to 1.1 A at 24 V or 0.22 A at 125 V.

This characteristic makes the switch suitable for controlling low-power motors as well as signal circuits and safety systems requiring rapid disconnection.

Installation and Operating Conditions

The device is ready for quick connection thanks to the factory-installed connection cable, eliminating the need for additional wiring inside the distribution box, which accelerates installation work. The housing dimensions (width 31.5 mm, height 29.5 mm, and sensor length 92 mm) allow installation even in tight machine spaces.

The device operates stably across a wide ambient temperature range: from -25 °C to +70 °C. This makes it suitable for use in unheated warehouse halls during winter as well as near heat sources in summer. The absence of electronic output functions or communication interfaces means this is a classic electromechanical solution—simple, durable, and easy to diagnose for service technicians.
