Telemecanique XCSZP1 Coded Magnet for XCSDMP
The Telemecanique XCSZP1 is a coded magnet designed for use with XCSDMP safety interlocks. It serves as a replacement magnet for non-contact switch actuation and features two elongated and two circular mounting holes—0.17 inches (4.5 mm) to accommodate precise alignment. This magnet is intended to complement safety interlock systems by ensuring accurate actuation without physical contact wear, helping extend interlock life in demanding industrial environments.
POWERTEC 120V, 18A Magnetic Switch for Router Table
The POWERTEC 71969 magnetic switch is a safety upgrade designed for tool benches, router tables, and drill stands. It includes an emergency stop button and is UL-listed (UL508, UL61058-1) for motor loads up to 18 amps. This model emphasizes preventing unintended tool restarts after outages, a critical feature in busy workshops where exposure to moving parts presents a risk to operators.
POWERTEC 120V, 18A Magnetic Switch with 5.5 Ft Cord
This POWERTEC model adds a 5.6-foot cord for versatile mounting on benches and stands. It preserves safety with an emergency stop button and ensures tools cannot restart after a power disruption. UL-listed for motor loads, it suits a range of power tools including table saws, drill presses, and band saws, aligning with common workshop safety standards.
XCSDMC5902 Coded Magnetic Switch
EMGQQ’s XCSDMC5902 coded magnetic switch offers a 1 NC + 1 NO configuration with staggered mounting for XCSDMC safety interlocks. The product is designed to integrate with coded interlock systems that require non-contact actuation, reducing wear and enabling safer maintenance cycles in continuous operation environments.
SCHMERSAL BNS33-11Z-2M Coded Safety Actuator
The Schmersal BNS33-11Z-2M is a 100 V coded actuator with a non-contact magnetic actuation approach. Though framed for more industrial interlock systems, its coded design reduces false triggering and supports higher safety reliability in environments where safeguarding personnel from machine contact is essential.
ZENGZHIC Magnetic Safety Switch for Treadmills
The ZENGZHIC universal magnetic safety switch is marketed for treadmills but demonstrates the versatility of coded magnetic safety devices. It features a compact circular design, one-meter lead wire, a 0.7-inch magnet diameter, and a 1.1-inch outer plastic diameter. These attributes support secure actuation and straightforward installation across various fitness and light-industrial applications.
Buying Guide: Key Purchase Considerations
- Actuation Type and Coding: Choose a magnet or actuator with coding to minimize accidental engagement and to pair correctly with your interlock system (NC/NO configurations, staggered mounting, and non-contact actuation).
- Electrical Ratings: Verify voltage and current ratings align with your equipment (120 V, 18 A is common for shop tools). Ensure UL or equivalent approvals for safety and compliance.
- Mounting and Hardware: Review the mounting hole dimensions and screw types. Elongated, counter-bored, or standard holes affect alignment ease and durability in vibration-prone environments.
- Environmental Durability: If the setup is exposed to dust, moisture, or temperature changes, look for waterproof or ruggedized designs and materials suitable for workshops or industrial floors.
- Safety Features: Prioritize devices with emergency stop capabilities, non-restart after outages, and protection against overloads to reduce operator risk during tool operation.
- Interlock Compatibility: Confirm compatibility with your existing safety interlock family (XCSDP, XCSDMC, or SCHMERSAL lines) to ensure reliable, repeatable actuation and safe lockout behavior.
- Wiring Options: Consider cord length and plug configurations. Longer cords provide flexible mounting but may require additional strain relief and wiring planning.
- Maintenance and Replacement: Favor coded magnetic switches that minimize wear from mechanical contacts and provide predictable replacement cycles.
In summary, selecting a coded magnetic safety switch hinges on compatibility with your interlock system, the required electrical specifications, mounting flexibility, and the environment where it operates. The options listed here cover a range of workshop and industrial needs, from router table safety to heavy-duty interlock assemblies, offering reliable solutions for reducing startup hazards and safeguarding operators.
