Product Overview

The SICK i110RP safety switch is a reliable, robust safety device designed for use in industrial environments where safe mechanical protection is essential. It features a slow-action switching element to ensure precise and safe response during actuation events. Constructed with a zinc diecast housing, the i110RP offers high durability and resistance to environmental factors. With an IP66 enclosure rating, it provides excellent protection against dust and water ingress. The switch is designed for individual wiring only, without support for series connections, ensuring safe and independent operation in critical safety circuits. Its rated operating current supports both 24 V DC and 240 V AC applications, making it suitable for a wide range of industrial automation tasks where reliable safety switching is required.

Key Features and Technology

The i110RP employs a slow-action switching element to ensure safe and stable operation during mechanical actuation events. This technology minimizes false triggering and ensures consistent performance under dynamic conditions. The switch operates with a minimum switching voltage of 5 V DC and requires only 5 mA at that voltage for actuation, ensuring low power consumption while maintaining sensitivity. It is designed with diagnostics for individual wiring, enabling reliable detection of faults in the circuit. The device supports safe operation within defined electrical limits, including a rated insulation voltage of 250 V and an impulse withstand voltage of 2,500 V. Its T6 short-circuit protection ensures robustness against transient overcurrent events, enhancing safety in high-vibration or high-stress environments.

Technical Characteristics

The SICK i110RP has a rated operating current of 3 A at 240 V AC and 2 A at 24 V DC. It operates with a switching voltage of ≥5 V DC and a switching current of 5 mA (at 5 V DC). The device is rated for an insulation voltage (U_i) of 250 V and an impulse withstand voltage (U_imp) of 2,500 V. It features a maximum actuation frequency of ≤3,600 times per hour. The housing is made from zinc diecast material and has dimensions of 40 mm × 204 mm × 56 mm with a net unit weight of 0.898 kg. Connection is achieved via a cable gland with one M20 thread, supporting conductor cross sections up to 1.5 mm². The device is certified for operation in harsh environments due to its IP66 enclosure rating and wide ambient temperature range.

Configuration and Integration

The i110RP is designed for individual wiring only and does not support safe series connection. Each switch must be wired independently, with diagnostics enabled per device to ensure reliable safety circuit integrity. Connection is made via a cable gland with one M20 thread, accommodating conductors up to 1.5 mm² cross-section. The device operates within standard industrial power supply conditions (24 V DC or 240 V AC), and its switching principle ensures safe response during actuation events. Integration requires careful attention to wiring standards and proper grounding for optimal performance. No additional components or external circuitry are required beyond the basic connection setup, simplifying installation while maintaining compliance with safety regulations.

Operating Environment

The i110RP is designed for operation in ambient temperatures ranging from –25 °C to +80 °C. It can be stored within the same temperature range, ensuring stability during both active use and long-term storage. The IP66 enclosure rating provides full protection against dust ingress and water jets from any direction, making it suitable for outdoor or high-humidity environments. The device is built to withstand mechanical stress and environmental exposure without degradation in performance. It is not rated for use in explosive atmospheres or hazardous areas unless specifically approved under applicable safety standards. Its robust construction ensures consistent operation across a wide range of industrial conditions.

Industrial Applications

The SICK i110RP safety switch is ideal for applications requiring reliable mechanical safety protection, such as machine guarding, door interlocks, and emergency stop systems. It can be used in automated production lines where safe shutdowns are required upon physical contact or movement. Its slow-action switching element ensures precise response to actuation events, reducing the risk of unintended operation. The device’s compatibility with both 24 V DC and 240 V AC power supplies allows flexibility across different industrial systems. Due to its IP66 rating and wide temperature range, it is well-suited for use in outdoor or high-dust environments such as material handling equipment, packaging lines, and conveyors where environmental exposure is significant.
