Single-position limit switch PEM1G15X A37-A86X

Robust protection for control circuits in harsh conditions

This single-position limit switch, designated as PEM1G15X, is a solution designed for reliable position detection in industrial automation. Its metal housing, protected by a powder-coated finish, resists mechanical damage and corrosion, which is crucial in production environments. Thanks to its IP67 protection rating, the device can operate in areas exposed to dust and temporary immersion in water, eliminating the need for additional enclosures.

Precise construction and mounting functionality

A key structural element is the perpendicular roller actuator, which enables smooth, inertia-free detection of obstacles. This roller facilitates angled mounting and reduces the force required to activate the sensor, which is essential for the automation of production lines. The device features compact dimensions: a width of 31.5 mm, a height of 16 mm, and a sensor length of 70 mm, allowing installation even in tight machine spaces.

The device features positive opening action, meaning that the normally open (NO) contact opens mechanically even if the normally closed (NC) contact welds shut. This is a fundamental safety feature for installations, guaranteeing physical interruption of the control circuit in the event of a mechanical failure. The absence of a visual status indicator does not affect functionality, as the circuit status can be easily checked using a multimeter or by observing the PLC controller's response.

Application and electrical parameters

This limit switch is equipped with a connection cable, which speeds up installation and eliminates the need to purchase separate connectors. It features one normally open (NO) contact and one normally closed (NC) contact, providing flexibility in designing electrical schematics—it can be used for both starting and stopping processes. The delayed contact switching function allows for the elimination of short-term mechanical vibrations when the roller strikes an obstacle.

Selecting the device for a specific control system requires consideration of voltage and current type. In alternating current circuits (AC-15) at 230 V, the device handles a current up to 1.5 A, while at a lower voltage of 125 V, this capacity increases to 3 A. Conversely, for direct current circuits (DC-13), the characteristics differ: at a standard control voltage of 24 V, a current up to 1.1 A is possible, whereas at a higher voltage of 230 V, the maximum current drops to 0.1 A. This distribution of parameters makes the limit switch suitable for both controlling network contactors and directly connecting PLC inputs or high-voltage DC coils.

The device operates stably within a wide ambient temperature range from -25 °C to +70 °C, making it suitable not only for production halls but also for outdoor applications or in unheated warehouses. The lack of a communication interface and safety functions means this is a classic actuator intended for simple logic circuits, not for safety systems of PL or SIL categories—for such applications, dedicated safety switches with dual positive-opening contacts should be selected.
