Technology Analysis

IP67 Water & Dust-Resistance Technology

IP (Ingress Protection) is the universal ingress-protection standard. In IP67, the first digit “6” is the highest dustproof rating, providing complete dust-ingress prevention; the second digit “7” means it can be immersed in 1 m of water for short periods (30 minutes) without being affected.

LDER achieves IP67 ingress protection through measures such as dual-layer silicone sealing rings, ultrasonic welding, ePTFE waterproof breathable membranes, and connector-end potting sealing — ensuring normal operation in rain, high-pressure wash-down, and long-term stable operation in dusty mine environments.

Rating	Dustproof	Waterproof	Applicable Scenarios
IP54	Protected against light dust	Splash-proof	Indoor light-dust environments
IP65	Fully dustproof	Protected against low-pressure water jets	Outdoor general environments
IP67	Fully dustproof	Protected against short-term immersion	Harsh industrial / outdoor environments (LDER standard)
IP68	Fully dustproof	Protected against continuous submersion	Underwater operating equipment

470 MHz Wireless-Communication Technology

LDER remote controls operate in the 470 MHz band, which is China’s open Industrial / Scientific / Medical (ISM) band and does not require a wireless radio license. 470 MHz is in the low UHF range, with a wavelength of about 64 cm; it has strong diffraction and can penetrate 1–2 layers of metal plates or reinforced-concrete walls. Measured open-area range is ≥200 m.

Environment	Actual Measured Range	Description
Open area (no obstructions)	≥200 m	Standard test range in open ground
Ordinary workshop (with steel beams)	120–180 m	Steel-beam structure causes partial obstruction
Densely structured factory (multi-layer structure)	80–120 m	Multiple walls / equipment block the signal
Mine / tunnel	50–100 m	Enclosed space — complex multipath

Dual-Speed Control Principle

Dual-speed control means each motion direction provides fast (high speed) & slow (low speed). The operator presses the button to the first position for low-speed operation; continuing to press to the second position switches to high-speed operation. A typical operating procedure is: lift into position using high speed to bring the load quickly above the target area, then switch back to slow speed for precise lowering into place.

Comparison Item	SK Single-Speed Series	DK Dual-Speed Series
Output per Button	1 signal set (open / close)	2 signal sets (fast / slow)
Suited Motors	Single-speed motors	Dual-speed motors
Control Precision	Average	High (two-speed switching)
Typical Applications	Simple start / stop (hoists, winches)	Precise positioning (cranes, overhead cranes)
Price Range	CNY 268–CNY 728	CNY 818–CNY 978

Safety-Protection Mechanisms

Emergency-Stop ButtonLarge red mushroom-head button — one button disconnects all motion outputs; response time <100 ms
Key SwitchPrevents unauthorized operation — each operator is assigned one key
Signal-Loss ProtectionIf the transmitter & receiver lose link for 1 second, the system auto-stops the machine
Overload ProtectionBuilt-in overcurrent protection in the receiver — auto-disconnects in a short-circuit
Interlock ProtectionForward / reverse operations are interlocked to prevent conflicting commands on the same output
Rolling-Code TechnologyEach communication uses a different code, preventing signal replication and replay attacks
Auto Frequency HoppingWhen co-channel interference is detected, the system automatically switches communication channels

Frequently Asked Questions

How do I choose an LDER remote control?

Selection is in two steps: 1. Choose the button count — count how many operations your equipment requires; 2–3 choose 6 buttons, 4–5 choose 8 buttons, 6–7 choose 10 buttons (most common), 8+ choose 12 buttons. 2. Choose the series — if you only need “open / close” control, choose SK single-speed; if you need “fast / slow” two-speed speed control, choose DK dual-speed. If unsure, the LD-10DK is the first choice for 90% of scenarios.

Why is the LD-10DK called the “Golden Configuration”?

The LD-10DK is a 10-button dual-speed model. The 10-button layout enables coverage of the vast majority of crane equipment control requirements (lift / lower / large-vehicle forward & reverse / small-vehicle forward & reverse + auxiliary functions), while the dual-speed function lets operators switch between high-speed operation and low-speed precise positioning. Considering function coverage, operation convenience and value, the LD-10DK is the first choice for industrial users.

What voltages does the LDER remote control support?

The SK single-speed series supports AC/DC 24 V–500 V ultra-wide voltage, covering all industrial power supplies. The DK dual-speed series supports 36 V / 220 V / 380 V three options selectable — specify the voltage at purchase.

How far is the remote-control range? Is the signal susceptible to interference?

The actual measured range in open areas is ≥200 m. The product uses the 470 MHz band + unique code + rolling-code technology for strong anti-interference. Each remote control is factory-loaded with a unique code, so when multiple devices operate together on the same site, they do not interfere with each other. If the transmitter loses contact with the receiver, the receiver performs an emergency auto-stop within 1 second.

Can it be used in the rain?

Yes. LDER’s full lineup reaches IP67 waterproof rating — using it in the rain is no problem, and even short-term submersion does not affect function. However, we recommend drying and wiping after use to keep the product clean.

How long is the warranty? What does “Old-for-New” mean?

2-year warranty from the date of purchase. Non-human damage within the warranty scope is eligible for free replacement. The “2-Year Old-for-New” service means: if a product develops a non-human fault within the warranty period, it can be directly replaced with a brand-new product — no repair wait needed. Products past the warranty period can also enjoy the Old-for-New service (price difference must be paid).

What do “1 Receiver + 1 Transmitter”, “2 Receivers + 1 Transmitter” mean?

“Receiver” refers to the receiver device; “Transmitter” refers to the remote control (radio device). 1 Receiver + 1 Transmitter = Standard Kit (1 transmitter + 1 receiver); 2 Receivers + 1 Transmitter = 2 receivers + 1 transmitter, suited to controlling one piece of equipment from two locations; 1 Receiver + 2 Transmitters = 1 receiver + 2 transmitters, suited to shared use across multiple shifts or dedicated-equipment use.
