By:SourceFactoriesAs production lines add automated cells and collaborative robotics, demand for fail-safe edge sensing has never been higher. Sourcing managers often struggle to find safety relays that reliably interface with pressure-sensitive mats and edge sensors…
Company Profile
Qinghe County Kaitian Safety Protection Technology Co., Ltd. is a China-based supplier listed within the Electrical & Electronics category. The company's product range includes edge switches, impact switches, and safety mats, positioning it as a focused provider of machine safeguarding components. The KT-SR31A safety relay is part of this portfolio, designed specifically for edge sensor and mat sensor integration. Buyers seeking full company audit details, certifications, or factory capabilities should contact the supplier directly through the platform.
Applications
Safety relays serve as the monitoring backbone for protective devices such as pressure-sensitive mats and edge sensors. The KT-SR31A model accepts DC input and is rated for a minimum load of 10 mA at 5 V, making it suitable for low-power signaling from edge sensor mats. In automated production environments, such relays evaluate the state of connected safety devices and help maintain controlled stop functions when a mat is actuated.
Application Scenarios
Electrical & electronics assembly lines benefit from safeguarding robotic cells where edge mats detect operator intrusion and trigger a safety stop. Material handling systems such as AGVs and conveyors equipped with edge sensors require compact relay modules that fit into tight control cabinets. Machinery retrofits upgrading older machines with modern sensing edges often demand a relay that can interface with existing DC control circuits without extensive rewiring. These scenarios reflect common buyer needs in the relay and contactor category, though specific application validation remains the responsibility of the integrator.
Product Description
Model KT-SR31A is an electronic safety relay with protective characteristics. Key specifications and corresponding buyer advantages are outlined below:
- 22.5 mm width: Saves cabinet space, enabling high-density control panel layouts.
- DC electricity type: Aligns with low-voltage safety circuits common in edge and mat sensors.
- Minimum load 10 mA / 5 V: Monitors small signal currents from pressure-sensitive devices without nuisance tripping.
- Dimensions 114.5 mm × 100.5 mm × 22.5 mm: Predictable footprint for panel planning.
- Carton packing: Standard export packaging suitable for distribution.
The listed unit price is US$75.00, though volume pricing and customization may affect final cost.
OEM & Customization
The supplier indicates that specifications can be customized. Buyers can request adjustments to connector styles, labeling, or packing configurations to match regional distribution requirements. Production capacity is reported at 500,000 units, suggesting availability for both sample orders and larger procurement programs. Detailed customization parameters and minimum order quantities should be confirmed with the sales team.
